LTCC_filter

The Design of 2.4GHz LTCC Band-Pass Filters withEnhanced Stop-Band CharacteristicsLeung Wing Yan KittySept.15,2001IntroductionNowadays,the development of CAD tools in assisting circuit design is of great importance for increasingly complex structures.In this application notes,the design of a 2.4GHz Band-pass filters implemented by the Low Temperature Co-Fired Ceramic (LTCC)technology is introduced.To facilitate this LTCC design,an electronic design automation (EDA)tool,Advanced Design System (ADS),developed by Agilent Eesof is applied here.TheoryRealization of the transfer functions of passive band-pass filters in practice is a challenging work.The transfer characteristic should offer a sufficient attenuation in the stop-band,while providing a flat pass-band with small insertion loss.One of the options to enhance the stop-band characteristic is by the insertion of transmission zero.Fig.1illustrates the structure for the realization of transmission zeros such that:By introducing such characteristic into a standard band-pass filter prototype,the stop-band characteristic of the filter can be improved.Fig.2depicts a second-order Butterworth filter after the introduction of the characteristic shown in Fig. 1.Based on the design specifications,all the circuit elements in the filter can be evaluated explicitly by the design equations.For verification,the schematic as well as the physical layout of this filter are simulated by ADS ,which are illustrated in the following sections.ADS Application NotesMicrowave Laboratory,Department of Electronic EngineeringThe Chinese University of Hong Kong LC jB Fig.1Structure for the Realization of Transmission Zerosankresonant t C -L the of suceptance the is B where for 0z ωω==B z ωis the frequency at which the transmission zero locatedSchematic Simulation1.S-parameter SimulatorVarious simulators are available in ADS for specific purposes.For filter designs,S-parameter simulator is usually applied.By selecting this simulator,circuit characteristics,such as S-parameters,group delay and linear noise can be obtained.Y-and Z-parameters can also be found by the transformation from the s-parameters.Before simulation,some parameters have to be pre-defined (Fig.3),including the range of frequency under consideration (Start and Stop )and the number of points to be simulated (Num.of pts ).2.Drawing of SchematicThe components can be either inserted from thecomponent library window or from thecomponent palette appearing on the left-handedside of the schematic window (Fig.4).The s-parameter ports and the simulation setup boxare the essential elements for the s-parametersimulation.Fig.4illustrates a circuit ready forsimulation.3.Schematic SimulationOnce the circuit simulation is started,a simulationwindow showing the simulation time and runningstatus appears on the screen (Fig.5).Thegenerated data is stored in a Dataset ,which can bedisplayed in the Data Display Window .In ADS ,it ispossible to display the data in various formats,suchas linear plot,polar plot and smith chart.For clearillustration,markers can be inserted to the plots.Toundergo further computation on the data,mathematical equations can be inputted as well.Fig.6illustrated the simulated frequency responsesof the filter (Fig.4)with markers inserted at theresonant point (2.4GHz)V sourceZFig.2A Band-Pass Filter Structure with Improved Stop-Band CharacteristicFig.3Parameter Setting for S-parameter SimulationFig.4Schematic Window in ADSFig.5Simulation Window in ADSLayout Simulation1.MomentumAfter the schematic simulation,the schematic can be transformed into layout.For examples,capacitors can be realized by simple parallel plates or multi-layer structures.On the other hand,inductors can be realized in the forms of spiral or rectangular strip.Since the LTCC band-pass filter going to be designed is of multi-layer structure with passive components embedded inside,Momentum provided in ADS can be applied here for layout simulation.Momentum is an electromagnetic simulator for simulations on passive and planar circuits.2.Drawing of Physical LayoutThere are three ways to prepare a physical layout in Momentum :1)Convert from a schematic,2)Draw directly in the Layout Window and 3)Import from another design system.In Momentum ,various common file formats,such as DXF and GDSll can be imported.The finalized layout is shown in the Layout Window (Fig.7).As illustrated in the figure,different colours refer to the conductive materials in different layers.Before layout simulation,all the material properties in the layout have to be pre-defined.The settings for the substrate and metallization layers are illustrated,respectively,in Fig.8and Fig.9.Fig.6Data Display Window in ADSFig.7Finalized Layout in the Layout WindowFig.8Definition for the Substrate Layer Characteristicyout SimulationSimilar to the schematicsimulation describedpreviously,a frequencyplan has to be set beforethe simulation starts (Fig.10).The main parameters inthe plan include the sweeptype ,start and stopfrequency as well as thesample points limit underconsideration.After invokingthe simulator,a SimulationWindow (similar to Fig.5)showing the simulationprogress and the errormessages (if any)during thesimulation is invoked.The simulated data is stored in a Dataset ,which can be displayed in the Data Display window (similar to Fig.6).Note that a 3D view (Fig.11)of the physical layout at different angle and scale can be attained as well.Fig.9Definition for the Metallization Layer CharacteristicFig.10Frequency Plan for Layout SimulationConclusionTo facilitate LTCC circuit design,various types of CAD tools are required.ADS is one of the options.One of the important features in ADS is related to the feasibility in the linkages to many third-party softwares,which is considered to be a convenience for the circuitdesigners.Fig.113D View for the Finalized Layout。

混凝土材料实验室报告(英文版) Laboratory Report

Laboratory ReportIntroductionThis laboratory report is about concrete materials and some natures of concrete.Concrete is the basic engineering material used in most of the civil engineering structures. Its popularity as basic building material in construction is because of, its economy of use, good durability and ease with which it can be manufactured at site. The ability to mould it into any shape and size, because of its plasticity in green stage and its subsequent hardening to achieve strength, is particularly useful.Concrete like other engineering materials needs to be designed for properties like strength, durability, workability and cohesion. Concrete mix design is the science of deciding relative proportions of ingredients of concrete, to achieve the desired properties in the most economical way.With advent of high-rise buildings and pre-stressed concrete, use of higher grades of concrete is becoming more common. Even the revised IS 456-2000 advocates use of higher grade of concrete for more severe conditions of exposure, for durability considerations. With advent of new generation admixtures, it is possible to achieve higher grades of concretewith high workability levels economically. Use of mineral admixtures like fly ash, slag, meta kaolin and silica fume have revolution the concrete technology by increasing strength and durability of concrete by many folds. Mix design of concrete is becoming more relevant in the above-mentioned scenarioHowever, it should be borne in mind that mix design when adopted at site should be implemented with proper understanding and with necessary precautions. Concrete mix design manual is an attempt to increase the awareness among the users, about concrete mix design. It is made with intention of serving as ready reckoner for personnel, implementing mix design at site.Sieve analysis testObjective:1. Fineness modulus and grading curves of sand through the test , and master sand particle size of the extent and the particles with the relationship between master the basis for the judgment of the sand quality is good or bad , the selection of raw materials to prepare for the mixing of concrete2. The main purpose of the sieve analysis is to determine the Particle Size Distribution (PSD) of the sand. PSD is also known as Grain Size Distribution (GSD). This test is performed to determine the percentage of different grain sizes contained within a soil. The mechanical or sieve analysis is performed to determine the distribution of the coarser, larger-sized particles, and the hydrometer method is used to determine the distribution of the finer particles3.Exercises sieve analysis operation4. Familiar with the experimental equipmentApparatus:1.balance and scale:This is what we use in determine the weight of sand, cement, aggregate and water. So that we know the exact amount of quantity we use in order to be accurate in our test, also the balance (also balance scale, beam balance and laboratory balance was the first mass measuring instrument invented. In its traditional form, it consists of a pivoted horizontal lever of equal length arms, called the beam, with a weighing pan, also called scale, scale pan, or bason (obsolete[), suspended from each arm (which is the origin of the originally plural term "scales" for a weighing instrument). The unknown mass is placed in one pan, and standard masses are added to the other pan until the beam is as close to equilibrium as possible. In precision balances, a slider mass is moved along a graduated scale. The slider position gives a fine correction to the mass value. Although a balance technically compares weights, not masses, the weight of an object is proportional to its mass, and the standard weights used with balances are usually labeled in mass units2. Sieves with standard size of 10mm, 5mm, 2.36mm, 1.18mm, 600μm, 300μm & 150μm.Sieve is one important tool to be work as a filter. Each sieve has certain specifications of the hole The use of large pieces of objects to stay inside , small pieces out through the hole. So that can distinction different size of sands, aggregates and so on.3. Mechanical Sieve Shaker:Shaker to work is the use of complex rotation vibration generated by the oscillator excitation. Oscillator rotating hammer to the screen surface flat whirling vibration, rotating hammer to produce the conical rotary vibration sieve surface, the effect of the combined effects of the screen surface complex rotation vibration. Vibration locus is a complex space curved. The curve in the horizontal projection of a circle, an oval in the vertical plane of projection. Adjustment, rotary hammer excitation force can change the amplitude. To adjust the phase angle of under the hammer space, you can change the trajectory of the screen surface shape of the curveand change the trajectory of the screen surface materialThis is a Mechanical Sieve Shaker3.OvenThe ovenshell is generally thin steel plate , the surface paint , studio quality structural steel production . Shell and filled aluminum silicate fiber between the studio . The bottom of the heater installation , and can also be placed at the top or sides . The temperature control instrumentation with digital display smart table , PID regulation : Configure 999.99 hours time controller and the alarm device is connected . The operation of theoven is simple , fast and effective. Oven use Stainless steel heat pipe powered fever, after a high efficiency centrifugal fans use the air flow heat pipe heat to the studio internal.In the laboratory we use oven to dry the sample to a constant temperature ( 105 ± 5 ) ° C, to Make the experiment data more precise.Procedures:1)Weight about 500g of fine aggregate.2)Dry the samples to constant weight in the furnace at a temperature of 105˚ ± 5˚C.3)Measure the total mass of the example of dry aggregate.4)Pour the sample of dry aggregate into the combination of pore size from top tobottom sieve.5)Covered the top, placed on the Mechanical Sieve Shaker and keep shakingsieve for 5 minutes.6)Remove the set of sieves, weight the sample in each sieve7)Calculation and evaluationConcrete mix designObjective:Concrete is the second largest material consumed by human brings after food and water as per WHO. It is obtained by mixing cement, fine aggregate, coarse aggregate, water and other admixtures in required proportions. The mixture when placed in forms and allowed to cure becomes hard like stone. The hardening is caused by chemical action between water and the cement clue to which concrete grows stronger with age.The strength, durability and other characteristics of concrete depend upon the proportions of its ingredients, proportion of the mix, the method of compaction and other controls during placing, compaction and curing.Design of concrete mixes involves determination of the given constituents namely, cement, water, coarse aggregate and fine aggregate with admixtures if any.Factors to be considered in concrete mix design:1. Grade of Concrete:This gives the characteristic strength requirements of concrete. Depending upon the level of quality control available at the site. The concrete mix has to be designed for a target mean strength which is higher than the characteristic strength.2. Water-Cement RatioThe controlling factor for most of the desirable properties of concrete-things like strength, durability, shrinkage potential and permeability-is what’s know as the water-cement ratio. It really is as simple as it sounds. Just take the weight of water in a cubic yard and divide it by the weight of cement. Durable concrete mixes usuallyneed a water-cement ratio of .50 or less . So, to translate, that would mean a mix with 500 lbs of cement shouldn’t have more than 250 pounds of water or about 30 gallons.So, one of the first things we have to decide one when designing a mix is the water-cement ratio. Mixes with lower water-cement ratios produce higher quality concrete and they will usually be better for the finisher in terms of set times, bleeding and other important characteristics, provided the mix also has sufficient workability for easy placement and consolidation. For specification work, this water-cement ratio is usually determined by the service requirements or conditions for the concrete placement, and it is the first of many decisions that require the mix designer to balance a myriad of sometimes conflicting needsWater-Cement Ratio3. Cement and Other PowdersIt is very common for today's mixes to have more than one type of 'powder' included - in addition to Portland cement many mixes will fly ash or perhaps clag cement. Some mixes might have all three 'powders'. For purpose of water-cement ratio you total up all the powders and divide that weight by the weight of water in the mix.The trend for the future seems to be toward greater use of other powders. While there are several reasons for this, including better performance, two big reasons are the move toward building materials that are considered 'green' and reduction of costs. The use of oher powders gives the mix designer more tools on the quest to formulate mixes that meet varying performance requirements.Both fly ash and slag produce mixes that are denser and often stronger than plain cement mixes, and mixes utilizing more than one powder are often more finisher-friendly in terms of placement and finishing characteristic. Of course, such mixes behave differently than plain cement mixes and generally have slower set times, especially in cold weather. Once again, the mix designer has to balance these factors as he or she moves through the mix design process.Another trend that seems to be emerging is a move back to mixes with higher cementitious contents. There was a period of time when 'performance mix design' meant the cheapest possible mix that would meet the strength requirements for the job, often at the expense of other importantmix characteristics such as durability or ease of placement. These lean mixes are rarely a bargain for anyone, so don't be talked into saving a few cents and then having to deal with a mix that won't perform well for you or for the owner. In many cases the best performance enhancer you can build into a mix is to add some more powder. And remember, when you add some more powder you can also add additional water without compromising the water-cement ratio so this will often lead to a more workable mix that is easier to place and finish.4. AggregateAnother major factor that influences mixes is the type and amount of aggregate - sand and stone - that are included in the mix. The guiding principle of mix design is to pack as much aggregate into the mix as possible to make the mixes economical and to reduce the required paste volume (Paste is defined as the cement and other powders plus the water). The less paste (within reason) that a mix has, the less shrinkage potential it has (shrinkage is what causes most cracks in concrete) and the lower its overall cost.Especially important for mix workability is how the various size pieces of aggregate in both rock and sand are distributed. A well-graded aggregate will have a well-distributed range of particle sizes from large to small without having an overabundance of any one particle size. Well-graded aggregates usually have lower water demands and produce more workable mixes than aggregates that are more gap-graded. Gap-graded aggregates may have its of one size particle and very few of another and this usually leads to mixes that are difficult to place and finish even if a lot of water is added.Sometimes mix design problems are best solved by change the aggregates in the mix, by modifying the ratio of coarse aggregate to fine aggregate used in the mix, or by changing the size of coarse aggregate used in the mix. Local supply conditions and availability will determine how far you can go with these kinds of changes, but sometimes small changes can yield big results.5.AdmixturesAdmixtures are often the mix designer's best friend and they allow modern mix designs to be tailored to meet a large number of exacting performance demands while still maintaining high quality concrete. There are lots of different admixtures, but they generally fail into four categoriesDesign Procedure:(a)Arrive at the target mean strength from the characteristic strength required.(b)Choose the water cement ratio for target mean strength.(c)Arrive at the water content for the workability required(d)Calculate the cement content.(e)Choose the relative proportion of the fine and coarse aggregate.(f)Determine the mix proportion as given in Figure 3.12 (attached as appendix) toproduce concrete of 0.015m3.(g)Mix cement, fine and course aggregate in a mixer for 1 minute.(h)Add in water and mix approximately for another 1 minute.(i)When the mix is ready, proceed with the workability tests before casting it intocubes.Slump TestObjective:1. The slump test is to measure the workability of fresh concrete (Workability of concrete is a standard of construction operation and close-grained performance, is a comprehensive performance which includes mobility, cohesiveness and water retention).1. The slump of concrete is used to determine the actual construction of a standard concrete workability good or bad , the greater the slump , indicating that the better the workabilityApparatus:1. Slump cone:A mould consisting of the frustum of a cone which use for slump test2. Mixing rod:Standard 600mm long, 16mm diameter steel rod to mix concrete inside theslump cone3. Measuring scale4. ShovelProcedures:1)First with a damp cloth to wipe the wet slump cone and extinguishers, shovels, mixing rod, and other appliances. Slump cone is a cylinder the Catchy diameter of 100mm, the exit diameter 200mm, height 300mm, which have a horn –like shape.2)In accordance with mixture ratio to weight the different materials and stir them evenly3)Place the cone on a smooth, flat and clean surface.4)Fixed pedal, divide the fresh concrete into three layers load slump cone, The height of each layer is about One-third of the height of the slump cone. Pound 25 times from the edge to the center on each layer. The pound should be evenly distributed at the interface, shall not impact. When pounding the edge concrete in slump cone, the mixing rod can be slightly tilted. When pounding the bottom layer concrete, the mixing rod Should be run through the entire depth. When pounding other two layers, Should be inserted through this layer and insert the lower about 20mm ~ 30mm.5)After filling the slump cone, With steamed bread knife to cut excess mixing mixture, and smooth out the top of cylinder, remove the fresh concrete around thebottom of slump cone. Then immediately filed the slump cone.Finish filing procedure in 5-10seconds. Don’t make concrete effected by horizontal and torsion power. Complete t he whole process from start loading fresh concrete to filing the slump cone should be in 150 seconds.6)Put the slump cone near the pyramidal concrete specimen.Put a ruler on the top of slump cone and make it flat toward the pyramidal concrete specimen. Use another ruler to measure out the distance between the top of the pyramidal concrete specimen and the flat ruler we put just now. This data is the slump. Accurate to one millimeter. When one side of the concrete specimens landslides or side of the shear failure, another measure should be re- sampled . If the second still happens, the workability of the concrete is not good, should be recorded. Height of the slump cone(300mm) minus the height of the slump of concrete after the highest point , also known as the slump.7)When the slump of the concrete mixture is greater than 220mm , the just ruler measuring concrete extension of the final maximum and minimum diameters , under the conditions of the difference of the two diameter less than 50mm , the arithmetic product average to collapse and expansion of value, otherwise the test is invalid . SLUMP FLOW TEST precise value of 1mm, the results for rounding to the nearest 5mm.Compaction Factor TestObjective:To study and measure the workability of fresh concrete. Compaction coefficient refers to the roadbed compaction of dry density and actually reached by the compaction experiment get sample of the ratio of the maximum dry density K. The roadbed compaction quality to the degree of compaction K (%) said. Compaction coefficient gets closer to 1, show that the higher the compaction quality requirements. There is maximum dry density corresponding moisture content is the best water content, not least water contentApparatus:1. Two conical hoppers and a cylinder:2. Weighing machineProcedure:1. Ensure the apparatus and associated equipment are clean before test and free from hardened concrete and superfluous water.2. Weigh the bottom cylinder to nearest 10gm , put it back on the stand and cover it up with a pair of floats.3. Gently fill the upper hopper with the sampled concrete to the level of the rim with use of a scoop.4. Immediately open the trap door of the upper hopper and allow the sampled concrete to fall into the middle hopper.5. Remove the floats on top of the bottom cylinder and open the trap door of the middle hopper allowing the sampled concrete to fall into the bottom cylinder.6. Remove the surplus concrete above the top of the bottom cylinder by holding a float in each hand and move towards each other to cut off the concrete across the top of cylinder.7. Wipe clean the outside of cylinder of concrete and weigh to nearest 10gm.8. Subtract the weight of empty cylinder from the weight of cylinder plus concrete to obtain the weight of partially compacted concrete.9. Remove the concrete from the cylinder and refill with sampled concrete in layers.10. Compact each layer thoroughly with the standard Compacting Bar to achieve full compaction.11. Float off the surplus concrete to top of cylinder and wipe it clean.12. Weigh the cylinder to nearest 10gm and subtract the weight of empty cylinder from the weight of cylinder plus concrete to obtain the weight of fully compacted concrete.13. The compacting factor (CF) = ( weight of partially compacted concrete ) divided by ( weight of fully compacted concrete ) .Compressive strength testIntroductionThe concrete compressive strength is in the role of external forces, able to withstand the pressure per unit area, also refers to the ability to resist pressure destruction. When the limit of compressive strength is reached, materials are crushed. Concrete can be made to have high compressive strength, e.g. many concrete structures have compressive strengths in excess of 50 MPa, whereas a material such as soft sandstone may have a compressive strength as low as 5 or 10MPa.Compressive strength is often measured on a universal testing machine; these range from very small table top systems to ones with over 53 MN capacity.[1] Measurements of compressive strength are affected by the specific test method and conditions of measurement. Compressive strengths are usually reported in relationship to a specific technical standard.When a specimen of material is loaded in such a way that it extends it is said to be in tension. On the other hand if the material compresses and shortens it is said to be in compression.On an atomic level, the molecules or atoms are forced apart when in tension whereas in compression they are forced together. Since atoms in solids always try to find an equilibrium position, and distance between other atoms, forces arise throughout the entire material which oppose both tension or compression. The phenomena prevailing on an atomic level are therefore similar. On a macroscopic scale, these aspects are also reflected in the fact that the properties of most common materials in tension and compression are quite similar.The major difference between the two types of loading is the strain which would have opposite signs for tension (positive—it gets longer) and compression(negative—it gets shorter).Another major difference is tension tends to pull small sideways deflections back into alignment, while compression tends to amplify such deflection into buckling.By definition, the compressive strength of a material is that value of uniaxial compressive stress reached when the material fails completely. The compressive strength is usually obtained experimentally by means of a compressive test.Objective:A compression test determines behavior of materials under crushing loads. The specimen is compressed and deformation at various loads is recorded. Compressive stress and strain are calculated and plotted as a stress-strain diagram which is used to determine elastic limit,proportional limit, yield point,yield strength and, for some materials, compressive strength.Apparatus:1. compression-testing machine:This machine Applicable to all types of industrial paper tubes, chemical fiber paper tube -boxes and other types of container flat crush strength and deformation detection. With other related accessories, paper and cardboard ring crush strength,edge crush strength of corrugated board, corrugated board flat crush resistance ofcorrugated board adhesive strength testing.2.Concrete cube (from previous concrete mix design)3. Accuracy of one millimeter of the rulerProcedure:1. Take out the concrete cube (the cube form previous concrete mix design), this cube should be conservation to the required age by the standard curing conditions. Should do test as soon as possible to avoid the errors caused by changes in humidity.2. First check the size and shape, relative both sides should be parallel. Surface deviation of tilt should not be more than 0.5mm. Expenditure and edge length, accurate to lmm.

Spreadsheet Design, Verification and Validation, Use and

Spreadsheet Design, Verification and Validation, Use and Storage of Single-User Workbook Files in the US FDALaboratoriesPart IIbyDennis Cantellops, San Juan DistrictIntroductionTwo Laboratory Information Bulletins (LIBs)* covering the design, testing, verification and validation of spreadsheets have been prepared. Part I covers the general principles of spreadsheet application to be employed by several users (multi-users). This document (Part II) covers the spreadsheets to be used by single-users. It includes the use and storage of single-user spreadsheet files, the design aspects of spreadsheets and the verification and validation documentation for reporting in a regulatory environment. The discussion pertains to applications of the Microsoft Excel spreadsheet program.Due to the variability and complexity of sample analyses in FDA laboratories, analytical spreadsheet applications are often modified or created in actual time, as an analyst performs the analytical procedure.This paper relates to a single-user spreadsheet which is intended to be used by a single analyst, its creator, at one specific point in time for one time use depending of the type (single-user template or module). The single user spreadsheet can take various forms, but in general it is a single workbook file which is relatively simple because it is based on uncomplicated formula construction and does not contain macros, color-coding, cells protection or instruction worksheets. These features are not needed when the spreadsheet is intended for personal use, since the developer knows how to identify the raw data, cell locations of formulas, data-entry cells and cell addresses.The single user spreadsheet usually follows one of two basic options:A)A single-user workbook file can be created from a pre-developed single user template,which can contain approved and protected FDA forms (e.g. forms 431, 431a, and nutrition sample transfer form) and worksheet examples to aid the analyst in undertaking the sample analysis with the spreadsheet. The single user template is installed in a shared network location for use by the analysts. After the single user template is opened, it is saved as a single-user workbook file in a designated folder on a personal drive forpersonal use. The individual analyst can perform data entries and modifications to handle raw and secondary data. This single-user workbook file will increase in file size because the analyst will add the additional data including formula construction and additional formatting to complete the sample analyses.B)Another way to implement the single-user workbook file is to develop it from an emptyworkbook i.e. the analyst opens an empty workbook with unpopulated worksheets (or opens a previously used version from the local drive for use in the development of the necessary worksheets). For this article we shall refer to this process as using a single user module. During the creation and data population (data-entry) stages of the single-user workbook files, the analyst uses the same formatting practices as if it was a hand-written worksheet. The creator should perform in-process verification of any formulas by manual calculations during the developmental stage of the workbook file. These verifications should be documented and the evidence of correct operation should be attached with the future workbook results, either in paper form or as a separate worksheet if the verification is performed electronically using one of the referenced auditing tools. After completion, but prior to data use or approval, a second analyst verifies the calculations and data integrity of the printed sample worksheet using the visible data and the formulas displayed by the auditing tools. Therefore, the degree of the verification depends on the module complexity.In either of the two options mentioned, whether the single user workbook is created from a single user template or a single user module, the workbook file must not be transferred between the analysts. This is explained on section under “Managing Single-User Workbook Files”, page 14. In addition, a copy of the completed, verified and printed sample worksheet shall be maintained for documentation in the laboratory for future worksheet audits against the saved single user workbook file.The Power Pak Utility-PUP v5.0 (1) mentioned in Part I (2), or the ABB Spreadsheet Specification and Reporting Tool (3), can be used to audit the single-user workbook file templates during the testing and verification stages. It is important that effective and appropriate principles and procedures be applied to all stages of producing analytical spreadsheets. At the design stage, such principles include design standards, clarity of formulas, documentation, and user-friendliness. Furthermore, when the basic principles of software engineering techniques are applied to the construction of spreadsheet models, many errors are reduced or eliminated. Notes:1.Excel documents are called workbook files. Each workbook is made up of individual spreadsheets calledworksheets and sheets containing charts called chart sheets.2.In summary “spreadsheet” is only really used as a generic term whereas “single-user template”, is the readonly template, “single-user module” is the empty file ready for development and “single-user workbook”, is a saved analyst file (it can be created from either the template or a module).Below there is a table describing the differences between the Single-User Template1, Single-User Modules2, Single-User Workbooks3, and Multi-User application.Table 1 – Differences between analytical spreadsheets (Single-User Template1, Single-User Modules2, Single-User Workbooks3, and Multi-User)Spreadsheet AttributesSingle 1UserTemplateSingle 2UserModuleSingle 3UserWorkbookMulti-userCreated from empty spreadsheet 3Designed for use by one analyst 333Can be opened by more than one analyst 333 Can be populated by more than one analyst 3 May contain complex formulas 3 May contain macros 33 May contain color coded data-entry 333 Should protect cells, whenever possible 333 May contain instruction worksheets 333 May contain protected forms (e.g., 431 and 431a) 333 During population, formulas checked by calculator 3Second analyst verifies raw data entry 33 Second analyst verifies calculations integrity 3Electronic workbook file is saved 33 Contains unprotected worksheets 333May insert worksheets 333Needs validation documentation 33 Needs in-process verification of formulas during thepopulation stage3Should verify data-entry 33 Notes:1)The Single User Template1 and the Single User Module2 only exist prior to use. Once they are opened andsaved, they become a Single User Workbook3. The differences between single and multi-user spreadsheets are summarized in Table 1 above.2)For single-user workbook files standard formulas (such as “Round” and statistical functions) need to beverified for accuracy by the creator and by the reviewer (second check analyst). For multi-user workbook file applications the standard formulas (such as “Round” and statistical functions) need to be verified for accuracy by the developer during the testing and validation of the application. After the validation the reviewer only needs to verify data-entry entered by the end user.Analytical Spreadsheets and Hand-Written Worksheets; a ComparisonWhen only hand-written paper worksheets (e.g. FDA forms 431, 431a and calculation of results worksheets) are used, a hand electronic calculator is used to calculate sample results. Microsoft Excel single user workbook files can be created in a similar manner, as a simple reporting method, which includes an integrated calculator. For example, when using Excel to implement a simple calculation, the formula is entered into a cell, which will display the formula result. When using the paper or electronic process, the creator should perform in-process verification of formulas using an electronic calculator (hand electronic calculator or Windows Accessory calculator).Single-user workbook templates should be kept very simple. For example, they may involve the FDA form 431 and its general continuation form 431a for describing the sample. The template may also include other worksheets to aid the analyst in the population of raw data forms (fill-in-the-blank form) and development of secondary data forms (calculations and results) including the option to insert worksheets to create personal formatting capabilities. The equation editor (Microsoft Equation v3.0) can be used to describe the formulas in the analytical procedure. We can visualize the spreadsheet worksheet as an integrated electronic calculator in the background of the worksheet.In normal use, calculations are performed in the background of the spreadsheet, due to formulas inserted in the cells and the Excel formulas will reference other cells in the workbook to display the correct result. To aid the user (and the verifier) in the visualization and traceability of such formulas standard, Excel tools can give visual presentation (draws lines to the respective relative active cells) of the relationships between the cells that provide values to the formulas or the cells that depend on the formulas. Similar commands in the Auditing toolbar can locate the cells that provide data to the formula in the active cell and find the cells that depend on the value in the active cell.It is important to mention that both systems (paper hand-written worksheets and analytical spreadsheets) are developed in a similar manner according to the FDA Laboratory Manual of Quality Policies for ORA Regulatory Laboratories, the Good Laboratory Practices Manual in conjunction with any FDA worksheet-training module. The analytical spreadsheet construction mimics the paper hand-written worksheet. Labels (sample number, method reference, description of formulas) and formulas are located in comparable places to where they are situated on the paper hand-written worksheets. Therefore, when viewed on screen or printed the analytical spreadsheet should look similar to the paper hand-written worksheet.Types of Single-User Workbook FilesThere are several ways to implement single-user workbooks:a.Exclusive use Single-user Template. The analyst opens a read-only template file(usually saved as an XLT file), which may include protected forms (e.g. FDA 431 andFDA 431a continuation sheet) and other forms verified by the creator of the single-user template and approved by the management for sample documentation. This read-only template file should be installed in a shared or network drive. Also, this templateis likely to contain unprotected forms to aid the analyst in the population and/ordevelopment of the analytical worksheets. Analysts can create raw data worksheets(fill-in-the-blank forms) and secondary data worksheets (calculation and results) for aparticular analysis such as a USP drug assays or for a vitamin determination. Thissingle-user template can vary in complexity depending on the number of testsrequired for completion of sample analysis. Once in use, this template would be savedwith a unique name and would become a single-user workbook.b.Portion of work (single-user module). The analyst creates a module for a specific typeof analysis. Creation may begin from a blank workbook, or from a workbook alreadypopulated with data from another source. Examples of single-user modules includeworkbook files with data on content uniformity for a drug or the calculations requiredfor various assays. Also, a single-user module can consist of one or a combination ofthe following:1)Raw data and secondary data worksheets including supporting documentation(system suitability results, instrument parameters, HPLC/GC chromatograms).2)Secondary data only combined with other forms (for example Microsoft Word orExcel fill-in-the-blanks forms). Once in use, this module would be saved with aunique name and would become a single-user workbook.c.Fill-in-the-blank form (with no formulas). In this case, the analyst creates a workbookfor a specific analysis: a fill-in-the-blank form with no formulas being used within theworkbook. Usually these forms are used to enter hand-written raw data such asstandard and sample weights, sample dilution factors and their aliquots and dilutions.The creator may use the workbook to simply create table headings and formatting.d.Fill-in-the-blank form with formulas. In this case, the analyst creates a workbook fora specific analysis: a fill-in-the-blank form with formulas being used in the populationof tables or associated worksheets. Usually these forms with formulas utilize the rawdata (standard and sample weights, sample dilution factors and their aliquots anddilutions) which were hand-written on the fill-in-the-blank form with no formulas andthen this form with formulas automatically calculates the results using standard Excelfunctions such as SUM, AVERAGE, STDEV etc.An example familiar to FDA staff of an “Exclusive use Single-user Template”is the spreadsheet which includes forms FDA 431 and 431a, along with other forms used to aid the analyst to create or modify raw data and secondary data worksheets for specific assays. Single-user modules are also widely used in FDA laboratories and include a combination of one or more of Microsoft Office Programs such as Word, fill-in-the-blanks forms, Excel analytical applications and Excel fill-in-the-blanks forms.Good Laboratory Practice (GLP) RegulationsThe use of spreadsheets by FDA regulated establishments to judge the quality of a product is covered by cGMPs (4), GLP (5), regulations and ISO 17025 accreditation. The following are some of the requirements established by GLP regulations:•Configuration Management.•Written Standard Operating Procedures (SOPs).•Completeness of Data.•Raw Data.•Security.•Training.Note: For more detail on the requirement definitions, see Part I (2) of this series.Quality Standards and Guidelines (See ISO/IEC 17025 Guideline)The “General Requirements for the Competence of Testing and Calibration Laboratories”, (International Organization for Standardization ISO 17025) (6). Sections 4.3 Document Control, 4.12 Control of Records, and 5.10 Reporting the Results include several paragraphs on the manipulation of quality and technical records and the use of computers. For details, see Part I (2).General Spreadsheet Design (Single-user and Multi-User Spreadsheets)Spreadsheet structure is fundamentally similar to a computer program (7). Formula construction in a spreadsheet is essentially a form of computer programming. Therefore, it is important to apply basic software engineering techniques and quality assurance principles in the construction and use of spreadsheets. For spreadsheets this means the following:•Following a structured and documented approach to design, develop, and specify the spreadsheet.•Apply security principles to access the workbooks and data and the environment in which they are housed.•Thoroughly test the spreadsheet applications: considering correct cell inputs-outputs, correct cell and worksheets links, user defined formulas.•Fully document the above process using a comprehensive validation approach•Use the spreadsheets in a controlled and consistent manner, operated and maintained by trained individuals, with appropriate procedures.•Apply the principles of change control when spreadsheets are updated (multi-user applications and single-user template)Despite the controls needed to validate a spreadsheet it is important to remember the goal of the spreadsheet and the flexibility the analysts may require in its routine use. A spreadsheet isusually a set of worksheets and macro sheets designed to evaluate and organize data or to solve a particular problem (8). Such a solution should meet two design objectives:•Guaranteed correctness. If you cannot guarantee that your solution always yields the right answers, it is not effective and is dangerous. Design your solution to make errorsimmediately apparent.•Adaptability. Most likely, the task you want your solution to perform will change with time. Design the solution so that it is flexible and can be easily modified.Note: For more detail on “General Spreadsheet Design”, see Part I (2).Safety Design Procedures (Single and Multi-User Spreadsheets)The following are safety features for developing an analytical spreadsheet (9):•Separate primary (raw data) from secondary data. Identify and separate all raw data (Fig. 3) and secondary data (Fig. 4) from the analytical procedure. Provide aseparate sheet for the raw data. All the calculations, results, and graphs should be inthe Secondary Sheets 2, 3, etc. If needed, add sheets with Insert Æ Worksheet. Protectthe secondary sheets (see below). For very small or simple spreadsheets theseparation can be done using clearly headed tables for raw data and secondary data.•Use drop-down-lists whenever possible. This feature restricts the user to valid entries, when they are known beforehand. It is created by the sequence: Data ÆValidation ÆChoose “Setting”TabÆin “Allow”choose “List”Æin “Source”.Give the cell range where the allowed choices will be written. A message will beactivated when the cell is addressed. For setting up the message, select Data ÆValidation Æ choose Input Message Æand enter short instructions in the windowTitle. Optionally,choose: Error Alert and write the correction instructions in thewindow: Error Message. For example, in single-user the drop-down-list can be usedfor titles in front of the continuation sheet (431a). Example of titles are; Raw Data forAssay, Assay Calculation and Results, Content Uniformity Raw Data, ContentUniformity Calculations and Results, Dissolution Test Raw Data, Dissolution TestCalculations and Results, etc.. The continuation sheet (431a) is printed with the titlefor each analysis performed and in the back of the continuation sheet the raw-data orthe secondary data worksheet is printed.•Introduce the units in all appropriate cells. This feature allows creation of new number formats. For example, the units (e.g. mg/mL) used in the analytical methodscan be added by selecting from the Excel main menu bar: Format Æ Format Cells ÆChoose “Number”ÆChoose Category “Custom”Æ: Type: General. In the windowwhere General is typed, type the entry: “mg/mL” just after General and click OK.•Format numbers. Use the Round function and specify the number of decimal places to which the value should be rounded-off. For example, a formula to calculate an average with two decimal places would be:=ROUND(AVERAGE(Range), 2)Never round to less than a total of five places (including decimal places). For example, it is permissible to round the average to 87.333 but not to 87.33. This criterion is used for rounding-off the values of intermediate calculations. The weights and chromatographic peak areas should be reported with all their digits. The final results should be rounded to the least significant digit (LSD), using the appropriate official guidance. For example, the USP 28 / NF 23 page 4 provides the following rules:9Establish the position of the LSD.9If the digit to the right of the LSD is less than 5, eliminate all remaining digits after the LSD.9If the next digit is larger than or equal to 5, increase the LSD by one and eliminate all the digits beyond the LSD.The calculations always must be done with an excess of digits over the significant ones. Rounding off should be done only on the final results, intermediate data steps should be left without rounding and Excel should then be allowed to managed the calculation to its maximum available decimal places (this is generally far more accurate than hand calculators). Excel will not automatically round-off. The Round function should be included in the formula verification where rounding is performed.When considering the impact of rounding on calculations, always remain pragmatic and refer back to the assay accuracy and a comparison to a paper based method. Often calculators and manual calculation will give a different result to one performed by Excel as calculators can not handle as many significant figures as Excel can.•Calculations. In the calculation and results worksheet (secondary data, attachment B3), each result should be based on the results of the previous calculation so that the calculations progresses through the worksheet from top to bottom.•Statistics. Use the following Excel formulas when necessary (use Excel 2002 Office Assistant for Excel 2002 formula definitions):9Equations for calculating trendlinesThe equation for the straight line: y = mx + bwhere:m is the slopeb is the interceptOnce the slope and intercept are known, if one of the dependent variables is known, a value for the other dependent variable x’ or y’ can be calculated through the formulas: mb)(y x'−=b mx y'+=ExampleUse: =(Sample Response - INTERCEPT)/SLOPE.This formula gives the sample concentration as found by regression.9 Equation for calculating the interceptUse: =INTERCEPT(Response range of cells, Concentration range of cells). For example, INTERCEPT(A1:A6, B1:B6).9 Equation for calculating the slopeUse: =SLOPE(Response range of cells, Concentration range of cells). For example, SLOPE(A1:A6, B1:B6).9 Equation for calculating the correlation coefficientUse: =CORREL(Concentration range of cells, Response range of cells). This is the correlation coefficient. For example, CORREL(A1:A6, B1:B6).9 Equation for calculating the averageUse: =AVERAGE(Range of cells). For example, AVERAGE(A1:A6).9 Equation for calculating the standard deviationUse: =STDEV(Range of cells).For example, STDEV(A1:A6).For the % RSD: =(STDEV/AVERAGE)*100.Note: For more detail on “Safety Design Procedures”, see Part I (2) of this series.Design and Verification/Validation of Analyst Single-user Templates and WorkbooksThe design (follow above sections “General Spreadsheet Design and Safety Design Procedures”) of the single-user workbook must be performed by an analyst experienced in the used ofanalytical spreadsheets. For example, FDA forms 431 and 431a are developed and followed by any other forms that a particular laboratory section may need. The forms or worksheets to be included in this workbook file are selected by the creators (or analysts) and management of the particular laboratory section. Second, after compilation, the protected and read-only workbook file is installed as a template (XLT) in a shared or network drive with controlled access. In addition, this workbook file is flexible, allowing the analyst to create raw data (fill-in-the-blank forms) and secondary data (calculation and results) worksheets for a particular analysis such as a drug or vitamin assay. Also, the worksheet examples that are included in the template can be modified as per analyst needs.Therefore, when the analyst opens this protected and read-only single-user template from the shared or network drive the analyst must save the template in a designated protected folder in their private network drive directory with the sample number and abbreviated product name. From this stage on, the analyst will personalize this single-user workbook with new sample description data in the FDA forms (431, 431a) including new data from the analytical method in the subsequent worksheets.Protect cells when developing a form or formulas that should not change. Unprotect data-entry cells and color code for easy identification. Apply protection as follows: By default, Excel has all cells locked. First, unlock all data-entry cells in each worksheet by using the Format Æ Cells ÆProtection tab and remove both checkmarks. Next, apply protection to each of the other worksheets in the workbook file by selecting from the Excel main menu bar: Tools Æ Protection Æ Protect Sheet and, optionally, entering a password. This protects the secondary calculated data from unintentional changes.The verification or validation of the single-user template is performed according to the complexity of the workbook file. This may involve following the advice in this article or for more complex spreadsheets consider the Validation for Multi-User Applications in Part I (2). Follow the instructions below:•If the template contains only protected forms and example worksheets, perform 100% verification.•If the template contains protected formulas, validation should be performed (see multi-user validation procedure, Part I) and appropriate documentation produced. The workbook template can include examples of unprotected analytical worksheets that demonstrate the use of Excel formulas and functions.Figure 1a we can observe an analyst spreadsheet flow chart displaying the sequence of events as the worksheets are developed. Figure 1b displays a brief description of the differences between the single-user template and the single-user module. Figures 2, 3, and 4 show examples of the analyst spreadsheet (single-user) which include the “Analyst Worksheet” form FDA 431 (Fig. 2) and the raw data worksheet for an assay of Baclofen tablets (Fig. 3). Also, Figure 2 (FDA form 431) item “10. Summary of Analysis” under “Notes:” includes the software name and version (Microsoft Excel 2002) along with any upgrades or add-ins used to create the workbook file. Figure 4 shows a secondary data worksheet (calculation and results), which summarizes the rawDFS/ORALaboratory Information BulletinNo. 4349 Software Verification Page 11 of 25data for the calculations and results. Figure 5 shows an Analyst Spreadsheet / Worksheet Review which is used by the check analyst to review the completed printed worksheets. How to Use the Single-User Template The analyst will open a single-user template previously verified or validated. FDA forms 431 and 431a used for sample description along with other necessary forms to describe the sample are completed. The analyst will identify the first method to be used for the sample analysis along with the raw data and secondary data from the analytical procedure. If the template does not include the forms for raw data and secondary data (calculations and results) the analyst proceeds to create them following the formatting properties identified in the template. Then save the file template to create a single-user workbook in a designated protected folder located in a network drive for personal use, with the sample number and abbreviated product name. The analyst workbook files should flow logically with raw data first followed by the secondary data (calculation and results) plus system suitability results if a liquid or gas chromatographic assay was performed. All steps should be followed in a chronological order. A logical progression diminishes confusion when a second analyst is checking the workbook file. Verification of data integrity, raw data and calculation of results (secondary data) are in-process activities performed concurrently with the spreadsheet population. With single-user workbook files, it is seldom necessary to apply color-coding or cell protection. Specific instructions might be useful for seldom-used worksheets. On single-user templates, official FDA forms are protected and data-entry cells are color coded along with any specific raw data and secondary data worksheets for a particular analysis. Therefore, when analysts use a template with protected FDA forms and containing protected worksheets for any previously identified sample analysis (for example assay or dissolution test), and if other analyses are need to be included in the workbook file, the creation of additional raw data and secondary data worksheets do not need to apply color-coding or cell protection because the creator knows where the formulas and dataentry cells are located. Manually verify the calculations and results reported on the spreadsheet. This in-process verification must initially be done by the spreadsheet creator, then by the check analyst who verifies the calculations and sample integrity. The spreadsheet creator should consider the impact of rounding in the manual calculation, and attempt to minimize the chance of minor numerical discrepancies due to manual calculation rounding. After completion, any unused worksheet examples and dummy data included in the template should be deleted, maintaining only the data necessary for regulatory purposes. Design and Verification of Single-user Modules Single-user modules are the most commonly used form of spreadsheet in FDA laboratories. Analysts should follow the guidance given above in “General Spreadsheet Design and Safety Design Procedures”for the design of the single-user modules. This type of workbook file is。

本章的目的是介绍与实验设计(Experimental Designs)相关的研究方法,我们会先重复实验设计的定义,然后简介实验设计要注意的几个重点,及针对实验设计的常用的统计分析工具,最后我们会讨论几个实验设计的研究例子。

实验设计的定义及要注意的重点在第三章中,我们曾指出实验(Experiment)和准实验(Quasi-Experiment)设计的定义:「真的实验,要符合两个条件。

第一个是可控制我们要研究的原因(即X;自变项;Independent variable),或称为实验的情景(Experimental conditions),例如我们在研究某一新报酬制度(X)对员工生产力(Y;即依变项;Dependent variable)的影响时,如果我们可以设计新的报酬制度及保留原来的报酬制度以作比较,这便是可控制要研究的原因。

第二个是能随机分派实验的对象(Random assignment),在管理学的研究中,研究对象一般是个人,小组或整个机构。

用同一个例子,即某一新报酬制度(X)对员工生产力(Y)的影响,我们的研究对象便是员工(个人),如果我们可以把员工完全随机地分派到新旧两个报酬制度之中,然后观察﹑测量及比较他们的生产力,这样才是真正的实验。

」「不过,在进行研究中,我们不一定能随机分派实验的对象,例如虽然我们可以设计新的报酬制度来与旧的比较,企业不一定容许我们把他的员工随机分派。

这种祗有控制实验情景,而没有随机分派实验对象的研究设计,我们称为准实验(Quasi-Experiment),它提供了X与Y的共变及X先Y后的次序,但却不能完全排除其它也可能影响Y的因素,因此,在准实验的设计中,我们很多时会尽量考虑或甚至是测量了其它可能影响Y的因素(例如在进行研究前员工的生产力及他们的聪明才智),以逻辑推理或统计分析的方法来排除这些因素的可能性。

☆重要研究成果
◆1897年,约瑟夫· 汤姆孙研究阴极射线时发现电子。 ◆1935年,詹姆斯· 查德威克发现中子。
汤姆逊和卢瑟福最早证实了空气被X射线游离。从游离现象推导 出游离辐射 (放射线),也就是由原子释出能量范围广大的电磁波和粒 子辐射。汤姆逊最负盛名的贡献是探讨阴极射线的性质,也就是电子 的性质。他借着电场以偏转阴极射线;在过去是用磁场使它子偏转。 他终于证实电子为带负电的粒子。接着他又测定电子的质量,约为氢 原子核的二千分之一。在当时它子是被视为最小的粒子。 电子是属于次原子级的粒子,汤姆逊是证明次原子级粒子存在的 第一位,从此打开了次原子级的门户。后来汤姆逊证实电子和物质相 互作用的结果会产生X射线,而X射线和物质相互作用的结果却会产 生电子。 第一个原子模型也要归功于汤姆逊,也就是闻名的「葡萄干布丁 模型」。他绘出原子为一球形,充满了正电荷,同时也有相同数目的 负电荷(电子)。汤姆逊因在电子和气体导电两方面的卓越成就,获得 1906年度的诺贝尔物理奖。

在现代物理学的发展中,实验室 的建设具有重要的意义。以英国物理 学家和化学家H.卡文迪什(Henry Cavendish)(左图)命名的卡文迪什 实验室(Cavendish Laboratory)相当 于英国剑桥大学(University of Cambridge)的物理系。
国际著名的理论凝聚态物理学家爱德华兹 (Samuel Frederick Edwards,1928-),19831995年担任卡文迪什实验室第八任主任。他1949年毕 业于英国剑桥大学,获硕士学位,后赴美留学,1951 年获得哈佛大学博士学位。1953年到普林斯顿高级研 究院工作,次年回国,在伯明罕大学任教,19581972年在曼彻斯大学物理系任理论物理教授。1972年 到卡文迪什实验室任教授。1992-1995年任剑桥大学 副校长。 爱德华兹早期从事电动力学和量子场论研究,后 将量子场论的概念和方法应用到固体物理和化学物理 的各种问题上,包括液态金属、涡流、高分子物理及 非有序磁性系统。最新研究领域包括粉末材料及玻璃 的流动、拉胀性、神经网络的信息传递等。他在理论 高分子物理方面的成就尤为突出,其标志便是国际公 认的爱德华兹哈密顿量的问世。他发表论文250余篇, 专著2部以及若干有关科学技术的政策性论著布拉格(William Lawrence Bragg)继任实验室第五任主任。W.L. 布拉格与其父W.H.布拉格(William Henry Bragg)因在X线衍射分析晶体结构方面的成就共 获1915年度的诺贝尔物理奖。 在二次世界大战的时候,实验室的主攻方向 由主要从事原子物理和核物理基础研究转向对雷 达、核武器的军事研究。二战结束以后,鉴于从 科学研究和对于国家安全的重要性出发,英国政 府觉得核物理研究不应该在大学的一个实验室里 进行,就专门成立了一个国家实验室。所以从事 核物理研究的科学家就转移到国家实验室去了, 钱也转移过去了。这样,实验室不仅经费短缺, 研究方向也失去了。

在试验时,只考虑一个对目标影响最大的因素, 其它因素尽量保持不变,则称为单因素试验。把 这个因子如何划分为若干个水平称为处理设计。
1.质量性差异的单因子处理设计:这种单因子是不可 分割的,只能按它固有的单位进行处理设计。 2.数量性差异的单因子处理设计:这种单因子可以采 用不同的方法分割成不同的等级,每个等级即为一个处 理。分割常用的方法:

Therefore, all health and safety hazards must be identified and carefully evaluated so that protective measures can be incorporated into the design. The basic laboratory design features listed in this section illustrate some of the basic health and safety elements to include in all new and remodeled laboratories at Stanford. The subsections of Section 1.0 provide specific guidance on additional critical features of a general laboratory (e.g., fume hoods, hazardous materials storage, and compressed gases.) (Keep in mind, however, that no matter how well designed a laboratory is, improper usage of its facilities will always defeat the engineered safety features.)C.Architectural Considerations!Walls/Doors/Security1. The laboratory shall be completely separated from outside areas (i.e., must be boundby four walls).California Radiation Control Regulations, Title 17State of California, Department of Health Services, Radiologic Health Branch,Guide for the Preparation of Applications for Medical Programs (RH 2010 4/90)Having enclosed laboratories will help contain spills, keep unauthorized personnel fromentering areas where hazardous operations are performed, etc. These regulations applyspecifically to laboratories containing radioactive materials; however, Stanford UniversityEH&S interprets this to include all laboratories (e.g., general chemistry and electronics).2. The laboratory shall have means of securing hazardous and radioactive materials(i.e., lockable doors).CDC Select AgentsCalifornia Radiation Control Regulations, Title 17State of California, Department of Health Services, Radiologic Health Branch,Guide for the Preparation of Applications for Medical Programs (RH 2010 4/90)Having secured hazardous materials storage will keep unauthorized personnel from gainingaccess to them. These regulations apply specifically to laboratories containing radioactivematerials and CDC Select Agents; however, Stanford University EH&S interprets this toinclude all laboratories (e.g., general chemistry and electronics).3. Doors in H-occupancy laboratories shall have doors which swing in the direction ofegress. Doors serving B-occupancy shall swing in the direction of egress if theoccupant load is 50 or more. Where possible, all B-occupancy lab doors shouldswing out.1997 California Building CodeVersion 1.1/ 10-00Doors which swing in the direction of egress will facilitate occupant departures fromlaboratories during emergencies.!Windows4.If the laboratory has windows that open, they must be fitted with insect screens.CDC-NIH Biosafety in Microbiological and Biomedical Laboratories (BSL 2, D.5)Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines) App. G-II-B-4-eInsects, particularly flies, are known to be a potential carrier of disease. To keep insects outof the lab, the doors must be closed while an experiment is in progress, and windows shallbe screened if they are capable of being opened. These references apply specifically tolaboratories containing biological materials; however, Stanford University EH&S interpretsthis to include all laboratories (e.g., general chemistry and electronics).!Flooring5. The floor must be non-pervious, one piece, and with covings to the wall. This can beachieved by use of glue, heat welded vinyl flooring, epoxy coated concrete slab, etc.NBS Handbook 92IAEA, Safe Handling of RadionuclidesGuide for the Preparation of Applications for Medical Programs (RH 2010 4/90)Floors should be coved up walls and cabinets to ensure spills cannot penetrate underneathfloors/cabinets. Tiles and wooden planks are not appropriate because liquids can seepthrough the small gaps between them. These references apply specifically to laboratoriescontaining biological and radioactive materials; however, Stanford University EH&Sinterprets this to include all laboratories (e.g., general chemistry, electronics, etc.).6.Floors in storage areas for corrosive liquids shall be of liquid tight construction.CCR, Title 24, Part 9, Sections 8003.1.7.2, 8003.14.1.2!Sinks7. Each laboratory must contain a sink for handwashing.CDC-NIH Biosafety in Microbiological and Biomedical Laboratories (BSL 2, D.1)Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines) App. G-II-B-4-dNBS Handbook 92IAEA, Safe Handling of RadionuclidesExposure to hazardous materials and/or pathogenic organisms can occur by hand-to-mouthtransmission. It is extremely important that hands are washed prior to leaving the laboratory.For this very reason, the sink should be located close to the egress. These references applyspecifically to laboratories containing biological and radioactive materials; however, StanfordUniversity EH&S interprets this to include all laboratories (e.g., general chemistry andelectronics).Version 1.1/ 10-00boratory sinks shall have lips that protect sink drains from spills.P.A. Ordinance. 16.09.032(b)(13)Sink lips or berms should be >= 0.25 inches and designed to completely separate the labbench or fume hood work area from the sink drain.!Chemical/Waste Storage9.Chemical storage shelves shall not be placed above laboratory sinks.P.A. Ordinance, 16.09.09110.Sufficient space or facilities (e.g., storage cabinets with partitions) shall beprovided so that incompatible chemicals can be physically separated. This will bebased on the chemical inventory and use projection provided by the PrincipalInvestigator to the project and EH&S. If the project scope cannot provide sufficientstorage the user must develop a written management control plan to include aspart of their local Chemical Hygiene Plan.CCR, Title 24, Part 9, Section 8001.9.8Materials which in combination with other substances may cause a fire or explosion, ormay liberate a flammable or poisonous gas, must be kept separate. Recommend thatsolvent storage not be located under the laboratory fume hood, as this is a location wherefires are most likely to occur in laboratories.11.Adequate space must be provided for the storage of waste materials.Good Practice per Stanford University EH&SAll labs should be designed to conveniently and safely accommodate the temporarystorage of biological, radiological, and chemical wastes based on laboratory useprojections. Wastes are generally stored in the lab in which they are generated, not incentralized accumulation areas.!Furniture Design and Location/Exit Paths12.All furniture must be sturdy. All work surfaces (e.g., bench tops and counters) mustbe impervious to the chemicals used.NBS Handbook 92IAEA, Safe Handling of RadionuclidesGuide for the Preparation of Applications for Medical Programs (RH 2010 4/90)CDC-NIH Biosafety in Microbiological and Biomedical Laboratories (BSL 2, D.3)Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines) App. G-II-B-4-bFor example, many microbiological manipulations involve concurrent use of chemicalsolvents such as formaldehyde, phenol, and ethanol as well as corrosives. The lab benchVersion 1.1/ 10-00must be resistant to the chemical actions of these substances and disinfectants. Woodenbench tops are not appropriate because an unfinished wood surface can absorb liquids.Also, wood burns rapidly in the event of a fire. Fiberglass is inappropriate since it candegrade when strong disinfectants are applied. Fiberglass also releases toxic smoke whenburned. These references apply specifically to laboratories containing biological andradioactive materials; however, Stanford University EH&S interprets this to include alllaboratories (e.g., general chemistry and electronics).13.The lab shall have a minimum aisle clearance of at least 24 inches. Main aisles usedfor emergency egress must have a clearance width of at least 36 inches.CCR Title 8, 3272(b)NFPA 45, Standard on Fire Protection for LaboratoriesClear aisles and exits are necessary to facilitate departure in the event of an emergency. Inpractice, lab aisles must be designed wider than 24” so that even with the presence of labstools and other miscellaneous items, a clearance of 24” is always maintained.b benches and other furniture must be placed a minimum of 36 inches from anexit.Good Practice per Stanford University EH&SLab benches must not impede emergency access to an exit. This is also applicable toplacement of other furniture and appliances such as chairs, stools, refrigerators, etc.b desks should be located near exit ways and in the path of fresh make up air.Good practice per Stanford University EH&SWill ensure that in the event of an emergency, employees working in “clean” areas (i.e.,their desk) do not have to pass through more hazardous areas to exit the laboratory.!Earthquake Restraints16. All equipment requiring anchoring shall be anchored, supported and braced to thebuilding structure in accordance with CCR Title 24, Part 2, Table 16A-O. Forexample, any equipment, including but not limited to, appliances and shelving thatare 60 inches or higher and have the potential for falling over during anearthquake, shall be permanently braced or anchored to the wall and/or floor.CCR, Title 24, Part 2, Table 16A-OThis practice keeps these items from falling in the event of an earthquake and assuresthat safety while exiting is not compromised.17. Must provide seismic lips ( 2”) on all laboratory bench shelving.Version 1.1/ 10-00Good Practice per Stanford University EH&SInstallation of seismic lips on shelving areas will prevent stored items from falling during aseismic event.18. Cabinets must be equipped with positive locking door latches.FEMA, Reducing the Risks of Nonstructural Earthquake DamageExamples include barrel bolts, safety hasps, and child-proof locks. These latches will notallow the cabinet door to open unless the locking mechanism is triggered. Magnetic orpinch-grip catches are not considered “positive locking” and hence should not be used.!Cleanability19. The laboratory must be designed so that it can be easily cleaned. Walls should bepainted with washable, hard non-porous paints.CDC-NIH Biosafety in Microbiological and Biomedical Laboratories, (BSL 2, D.2)Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines) App. G-II-B-4-aNBS Handbook 92IAEA, Safe Handling of RadionuclidesWooden and wood finish walls or floors are not appropriate because they can absorbhazardous and/or potentially infectious material, particularly liquids, makingdecontamination/remediation virtually impossible. These references apply specifically tolaboratories containing biological and radioactive materials; however, Stanford UniversityEH&S interprets this to include all laboratories (e.g., general chemistry and electronics).20. Spaces between benches, cabinets, and equipment must be accessible for cleaning.CDC-NIH Biosafety in Microbiological and Biomedical Laboratories (BSL 2, D.4)Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines) App. G-II-B-4-cLaboratory furniture must have smooth, non-porous surfaces so as to resist the absorptionof liquids and the harsh effects of disinfectants. Furniture must not be positioned in such amanner that makes it difficult to clean spilled liquids or conduct routine maintenance. Forexample, positioning a Class II biosafety cabinet in a limited concave space might not allowthe biosafety cabinet certifier to remove panels of the cabinet when recertifying the unit.These references apply specifically to laboratories containing biological and radioactivematerials; however, Stanford University EH&S interprets this to include all laboratories (e.g.,general chemistry and electronics).!Breakrooms21. The design of the laboratory building must incorporate adequate additional facilitiesfor food storage/consumption and personal hygiene tasks.California Radioactive Material License, 0676-43Version 1.1/ 10-00State of California, Department of Health Services, Radiologic Health Branch – DOHS 2010Stanford University Radiation Safety ManualPer 8 CCR 3368(b), 5193(d)(2), the storage and consumption of food, application ofcosmetics or lip balm, or handling of contact lens in areas they may be contaminated by anytoxic material or bloodborne pathogen is prohibited.D. General Ventilation Considerations (see also Section 1.1 for fume hood considerations)22. The room should have mechanically generated supply air and exhaust air.Good Practice per Stanford University EH&SThe air balance of the room cannot be adjusted unless there is mechanically generatedsupply and exhaust air.23. Mechanical climate control should be provided.Good Practice per Stanford University EH&S•Per ASHRAE 55-1992, comfortable temperature range are defined as follows: Winter: 69-76 °F (at 35% RH); Summer: 73-79 °F (at 60% RH)•Electrical appliances often exhaust heat into a room (e.g., REVCO freezer, incubator, and autoclave). Failure to take this effect into consideration may result in an artificiallywarm working environment. Windows must not be opened for a cooling effect since theroom air balance will be altered. A cool room must not be heated with a portable heaterthat may be a fire hazard.24.Cabinetry or other structures or equipment must not block or reduce effectiveness ofsupply or exhaust air.Good Practice per Stanford University EH&SMany supply diffusers and room exhaust room openings are located along laboratory walls.Storage of boxes near these openings may obstruct the circulation of air and supply orexhaust air functioning.25. General laboratories must have a minimum of 6-air changes/hour.Design and Construction of Inside Storage Rooms, General Industry Standard 29 CFR 1910.106, page 144, OSHA2206, Nov. 7, 1987 (OSHA, 1987).OSHA requires a minimum of 6 AC/HR in chemical storage rooms. Since most laboratoriesstore some quantities of chemicals, this regulation applies. OSHA has cited universitychemical storerooms for inadequate ventilation under this regulation.Version 1.1/ 10-0026. Laboratories must be maintained under negative pressure in relation to the corridoror other less hazardous areas. Clean rooms requiring positive pressure should haveentry vestibules provided with door-closing mechanisms so that both doors are notopen at the same time. Consult with SU Fire Marshal for design details.ANSI/AIHA Z9.5 – 1992, 4.11.4-4.11.5As a general rule, airflow should be from areas of low hazard, unless the laboratory is usedas a clean or sterile room.27.Air exhausted from the general laboratory space (as distinguished from exhausthoods) must not be recirculated unless one of the criteria listed in ANSI/AIHA Z9.5-1992, 4:10.2 are met. Exhaust air from hoods is never recirculated.ANSI/AIHA Z9.5-1992There is the potential for the recirculated air from general laboratory to contain aircontaminants generated from bench top research operations, etc.ConsiderationsE. Mechanical!Electrical28.Shall provide GFI protection to electrical receptacles above counter tops andwithin 6 feet of sinks. Receptacles that are not readily accessible or receptacles forappliances occupying dedicated space, which are cord-and-plug connected inaccordance with NEC Section 400-7A(6-8), are exempted.NFPA 70, Chapter 2, 210-829. The lab should be fitted with an adequate number of electrical outlets, which canaccommodate electrical current requirements of the equipment used within.Good Practice per Stanford UniversityThe lab may have several pieces of equipment, which require large amounts of electricalcurrent. Such items include freezers, biosafety cabinets, centrifuges, and incubators. Theroom design must take into consideration concerns such as electrical demand prior tooccupancy to avoid a potential power failure.30. Circuit breakers should be located outside the lab.Good Practice per Stanford University EH&SIn the event of an emergency, the laboratory may be unsafe to enter. Hence, the circuitbreakers for key electrical appliances should be located outside the lab.Version 1.1/ 10-00!Plumbing31.Valves for gas lines should be located outside the lab.Good Practice per Stanford University EH&SIn the event of an emergency, the laboratory may be unsafe to enter. Hence, the valves forgas and vacuum lines should be located outside the lab.32. Flexible connections should be used for connecting gas and other plumbed utilitiesto any freestanding device, including but not limited to biosafety cabinets,incubators, and liquid nitrogen freezers. Flexible connections should be appropriatefor the pressure requirements and should be constructed of material compatible withthe transport gas. A shutoff valve should be located within sight of the connectionand clearly marked.Good Practice per Stanford University EH&SSeismic activity may cause gas and other utility connections to break off. A flexibleconnection will minimize this potential considerably.33.Sink drains traps shall be transparent (e.g., made of glass) and easy to inspect orhave drain plugs to facilitate mercury spill control.P.A. Ordinance, 16.09.032(b)(14)If mercury-containing products or compounds will not be used, an exemption may berequested in writing to; Stanford University Environmental Quality Manager, StanfordUtilities Department, Mail Code 7270.34. Lab waste water lines shall be separate from domestic sewage, and a samplingpoints shall be installed in an easily accessible location outside the building.P.A. Ordinance, 16.09.060The sampling point shall be installed at a location where all building lab wastes aredischarged, before the lab waste line connects to the domestic waste line. The samplingpoint shall be designed so that it is perpendicular to the lab waste line, has a minimum 4inch diameter, has a cleanout screw on cap and is protected by a christie box. Thesampling point should not be located in an area where water from irrigation or flow fromstormwater runoff can accumulate.Version 1.1/ 10-00。
