标题:垂直轴偏差测定法一、目的本方法旨在规定液压气动用纤维增强橡胶软管和软管组合件(以下简称软管)垂直轴偏差的测定方法。

通过本方法,可以准确地评估软管的垂直轴偏差,以确保其在使用过程中的性能和安全性。

二、原理垂直轴偏差是指软管在自由悬挂状态下,其轴线与铅垂线之间的偏离程度。

本方法通过测量软管轴线与铅垂线之间的角度偏差来确定垂直轴偏差。

三、试验设备1. 测量尺:用于测量软管长度和直径。

2. 铅锤:用于确定铅垂线。

3. 角度计:用于测量软管轴线与铅垂线之间的角度偏差。

4. 支架:用于固定软管并保持其稳定。

四、试验步骤1. 在无风、无振动的环境下进行试验。

2. 将软管自由悬挂于支架上,确保软管不承受任何外部压力或拉力。

3. 使用铅锤确定铅垂线,并使用测量尺测量软管的长度和直径。

4. 使用角度计测量软管轴线与铅垂线之间的角度偏差。

每30°测量一次,共测量4次,以获得平均值。

5. 根据测量结果计算垂直轴偏差。

如需了解计算方法,请参考附录A。

五、结果分析根据试验数据,分析垂直轴偏差对软管性能和使用寿命的影响。

一般情况下,垂直轴偏差过大可能导致软管在使用过程中出现疲劳、磨损或破裂等问题。

为确保软管的安全性和可靠性,建议对垂直轴偏差进行严格控制。

六、结论本方法提供了测定液压气动用纤维增强橡胶软管和软管组合件垂直轴偏差的方法。

通过本方法,可以有效地评估软管的制造质量和使用性能,为保证其在安全可靠的环境下使用提供依据。

在未来的研究和应用中,可进一步探讨垂直轴偏差与其他性能指标之间的关系,以及优化软管制造工艺的方法,以提高产品质量和性能。

橡胶、塑料软管和软管组合件尺寸测量方法橡胶软管、塑料软管和软管组合件在工业生产中被广泛应用,它们的尺寸测量是非常重要的。

下面将介绍一种常见的橡胶软管、塑料软管和软管组合件尺寸测量方法。

首先,我们需要准备以下工具和设备:卷尺、外径卡尺、内径卡尺、千分尺、游标卡尺等。

1. 外径测量:将橡胶软管、塑料软管或软管组合件固定在平整的工作台上,使用卷尺或外径卡尺对软管的外径进行测量。

将卷尺或外径卡尺的一端对准软管的端部,并轻轻压缩软管使其紧贴刻度线,读取并记录外径的值。

2. 内径测量:使用内径卡尺或千分尺对软管的内径进行测量。

将内径卡尺的两只卡尺片插入软管的两端,轻轻扩张卡尺片使其贴紧软管内壁,并读取并记录内径的值。

如果使用千分尺,可以通过游标卡尺的刻度值来测量内径。

3. 长度测量:使用卷尺对软管的长度进行测量。

将卷尺的起点对准软管的一端,沿软管表面滑动卷尺直到另一端,读取并记录长度的值。

需要注意的是,测量前应确保软管表面没有明显的凹陷或损坏,以免影响尺寸测量结果。

此外,为了提高测量的准确性,可以进行多次测量并取平均值。

还可以使用更精密的测量设备,如显微镜、影像测量仪等来进一步提高测量的精度。

总之,以上介绍了一种常见的橡胶软管、塑料软管和软管组合件尺寸测量方法。

在实际操作中,还可以根据具体情况选择适合的工具和设备,以确保尺寸测量的准确性和可靠性。

橡胶软管、塑料软管和软管组合件在各行各业都有广泛的应用,例如汽车工业、化工行业、建筑业、制造业等。

为确保这些软管和组合件的质量和功能,尺寸的准确测量是至关重要的。

除了之前介绍的外径、内径和长度的测量,还有一些其他重要的尺寸需要测量和检查。

例如,壁厚是指软管的壁面厚度,是衡量软管强度和耐压能力的重要参数。

壁厚的测量可以通过测量软管的外径和内径,然后计算得出。

此外,软管的变径部分也需要进行测量,以确认其尺寸符合设计要求。

在进行尺寸测量之前,需要先进行软管的准备工作。

首先,将软管在室温下放置一段时间,使其达到环境的温度均衡。

A typical arrangement is shown in Figure A.1. The traversing arrangement shall be designed to ensure thata)the mid-point of the traversed length is coincident with the mid-point of the assembled hose and mandrel;b)the axes of the abrading tool and hose are mutually perpendicular at the mid-point;c)the plane of travel is parallel to the longitudinal axis of the test piece.Key1 abrading tool2 mandrel3 hose test pieceFigure A.1 — Typical test apparatusThis method requires a recording device, to record the number of cycles completed, and capable of being pre-set to terminate the test after completion of the specified number of cycles.This method requires means of applying a vertical force F, as specified in this product standard, to the abrading tool at the point of contact with the test piece.This method requires a mandrel, 150 mm long, on to which the test piece will fit tightly. It is essential that the mandrel is a tight fit in the test piece to prevent distortion of the test piece under the action of the reciprocating abrading tool. For accurate determinations, it is recommended that the mandrel is made of lightweight materials and is of hollow section, so that it is capable of supporting the abrading load but its mass is kept to an absolute minimum. If a solid mandrel is used, this shall be removed prior to weighing the test piece, taking care to avoid loss of material from the hose lining.A.2 MethodThis method uses an abrading tool manufactured from tool steel, heat-treated to give a minimum hardness of HV 890.The principal dimensions shall be as shown in Figure A.2. It is essential that the specified profile and surface finish are maintained, and that any extraneous material on the surface of the abrading tool is cleaned off before testing is started.Dimensions in millimetres1)The roughness grade N5 in accordance with EN ISO 1302 corresponds to a roughness value Ra of 0,4 μm.Figure A.2 — Abrading toolA.3 Test piecesEach test piece shall be a sample of hose of length 150 mm ± 0,5 mm. A minimum of three test pieces shall be tested.NOTE Selection of test pieces is permitted to ensure that there are no surface irregularities greater than 0,5 mm and that they are free from surface contamination.A.4 Condition of test piecesNo test shall be carried out within 24 h of manufacture. For evaluations which are intended to be comparable, the test shall, as far as possible, be carried out after the same time interval after manufacture. Before testing,test pieces shall be conditioned for at least 3 h at the standard temperature and humidity of 23 °C ± 2 °C and (50 ± 5) % relative humidity or 27 °C ± 2 °C and (65 ± 5) % relative humidity, in accordance with ISO 23529; this 3 h period may be part of the 24 h interval after manufacture.A.5 ProcedureWeigh each test piece on or off the mandrel and record the mass (m1). Mount the assembled test piece and mandrel in the apparatus, ensuring that the test piece is restrained from axial and/or rotational movement. Place the abrading tool in contact with the test piece, apply the vertical static force F as specified in this product standard, and start the machine. Continue until the specified number of cycles has been completed, then remove the test assembly from the apparatus and reweigh the test piece, either on or off the mandrel, as for the initial weighing. It is important to remove any loose particles of cover compound prior to weighing. Record the mass (m2) and the number of cycles completed.For guidance in preparing requirements in product standards, the static force should be 50 N or 100 N, the latter being selected where higher abrasion resistance if the cover is expected. If it becomes evident during the test that wear has taken place to an extent that the reinforcement is exposed, stop the test, remove the test assembly from the apparatus and reweigh. Record the mass and the number of cycles completed. All weighings shall be carried out to an accuracy of ± 0,01 g.A.6 Expression of resultsThe loss of mass Δm, in grams, is given by the formula:Δm = m1 – m2wherem1 is the mass, in grams, of the test piece before testing;m2 is the mass, in grams, of the test piece after testing.A.7 Test reportThe test report shall include the following information:a) a reference to this European Standard;b) a full description of the hose tested;c)the temperature at which the test was carried out;d)the number of cycles specified;e)the number of cycles completed on each test piece;f)the vertical static force F applied;g)the mass of each test piece before the test;h)the mass of each test piece after completion of the specified number of cycles or after discontinuation ofthe test;i)the loss of mass from each test piece;j)the average loss in mass of the three (or more) test pieces;k)any observations on the nature of wear, particularly any evidence of exposure of reinforcement; l)the date of the test.Annex B(normative)Type and routine testing of production hosesAnnex C(informative) Production acceptance testing。

TestforHOSE MADE FROM ELASTOMERIC MATERIALSMETHOD 7A.RESISTANCE OF HOSE LINING AND COVER TO LIQUIDS1SCOPE.This method determines the effect of specified liquid(s)on the lining and cover components of hose.2PRINCIPLE.Test pieces of lining and cover are immersed for a given time in the liquid after which the changes in volume and hardness are determined.3MATERIALS AND APPARATUS.(i)Liquids as specified—a fresh portion for each test.(ii)Vessels,inert to the liquids specified,of suitable size and shape to contain the test pieces and capable of being sealed to prevent the escape of the liquid.(iii)Such apparatus as is required or specified for determining volume and hardness.(See AS 1180.9A.)4TEST PIECES.Prepare three rectangular test pieces of lining and of cover 50×25mm as follows:(i)Carefully remove from the hose sample the cover and lining,using,if necessary,very small amounts of a suitable solvent.Where solvent is used dry up to 36h.(ii)Buff the test specimen only to the extent necessary to obtain smooth faces or toreduce to amaximumthicknessof1.6mm.The thickness of test specimen shallbe uniform to within ±0.13mm while that of specimens prepared from the samesample shall be of the same thickness within ±0.25mm.(iii)From the test specimens of lining and cover cut the three test pieces of each to the required dimensions with one stroke using a suitable die.N OTE :Should it be impossible to obtain test pieces having a buffed thickness of 0.80mm or greater,the manufacturer may be obliged to furnish a sample of the cured elastomer taken from the same quality of rubber from which the hose was made and having a cure equivalent to that to which the hose was subjected.5CONDITIONING OF TEST SPECIMEN AND PIECES.Conditioning shall beat 20±2°C and 65+10per cent relative humidity for at least 4h.as e d b y U N I V E R S I T Y O F W O L L O N G O N G o n 20 M a y 2007AS 1180.7A—November 197226PROCEDURE.6.1For Test Materials Immiscible or Non-Reactive with Water.(i)Determine the hardness of the test pieces by the test of AS 1180.9A and obtain the mean values for both the lining and the cover.(ii)Weigh each test specimen or piece to the nearest milligram in air (W ),and then in distilled water (W 2),ensuring removal of all air bubbles.Bubbles can be eliminated by adding a trace of surface-active agent, e.g.detergent,to the water.(iii)Dry each test specimen or piece by blotting with filter paper or a textile fabric that does not deposit lint.(iv)Place thethree specimensorpieces separatedin the container and add test material (at least 15times the volume of the test specimens or pieces)with anexcess such as to keep them totally immersed.N OTES :1.Place only test specimens or pieces from the same vulcanizote in any one container.2.If necessary provide a means for holding the test specimens or pieces completely below the surface.(v)Allow to stand at a temperature of 20±2°C for the specified time and remove the pieces.(vi)Remove the specimens or pieces and remove the test material from each.N OTES :1.If the immersion liquid is appreciably volatile at room temperature the maximum time for transference of each test specimen or piece after removal should be 30seconds.2.The method of removing the surplus will vary with the nature of the material.With mobile liquids such as iso-octane and benzene,remove and quickly wipe the test specimen or piece with a filter paper or piece of textile which does not deposit lint.Some difficulty may be experienced in completely removing viscous,non-volatile oils by this method and it may be necessary to dip the test piece quickly in a suitable volatile liquid such as acetone which does not deposit lint.(vii)Repeat step (i).(viii)Transfer each test specimen or piece to a tared,stoppered weighing bottle and determine its weight in air to the nearest milligram (W 3).Remove from the bottle and immediately determine its weight (W 4)in distilled water at20±2°C.6.2For Test Materials Miscible (or Reactive)with Water.Follow the procedure in 6.1above with the following amendments:(i)If the test material is not too viscous or volatile conduct weighings W 2and W 4in the test material instead of in water and use these weighings to determine ∆V bys e d b y U N I V E R S I T Y O F W O L L O N G O N G o n 20 M a y 20073AS 1180.7A—November 1972formula (1)in Clause

calculate ∆V by formula (2)in Clause 7.7CALCULATIONS.Calculate the change in volume ∆V using the appropriate formula below: (1)∆V (W 3−W 4)−(W 1−W 2)W 1−W 2 (2)∆V (W 3−W 1)d (W 1−W 2)whereW 1=the initial weight of the test specimen or piece in airW 2=the initial weight of the test specimen or piece in waterW 3=the weight of the test specimen or piece in air after immersionW 4=the weight of the test specimen or piece in water after immersiond =the density of the test material,in g/ml,at 20±2°CN OTE :Formula (2)may be only approximate if the immersion liquid is a mixture,because the density of the absorbed liquid may differ from that of the bulk.Also the density of any material extract from the rubber may differ from that of the immersion liquid.Percentage change in volume =∆V

Report any sign of damage to refluxed test pieces and the per centages of change in respect of both the tensile strength and the elongation properties.Accessed by UNIVERSITY OF WOLLONGONG on 20 May 2007This test method was approved on behalf of the Council of the Standards Association of Australia on 12 September 1972. This method was issued in draft form for public review as Doc. 1751.1AS 1180.7F—November 1972STANDARDS ASSOCIATION OF AUSTRALIA Australian Standard Methods of Test for HOSE MADE FROM ELASTOMERIC MATERIALS METHOD 7F. RESISTANCE OF HOSE LINING AND COVER TO OZONE1 SCOPE. This test is an artificial accelerated test which gives an indication of the resistance to cracking of the rubber components of hose to outdoor weathering by exposing them to ozone. Absence of certain factors in outdoor weather such as sunshine and rainfall limit the correlation. The method is derived from ASTM D1149—Test for Ozone Cracking of Vulcanized Rubber. 2 PRINCIPLE. The rubber components of the hose are placed under tensile strain in a chamber containing an ozone-air atmosphere under such controlled conditions as concentration and temperature and subsequently are assessed for cracking. 3 APPARATUS. 3.1 Ozone Test Chamber. Requirements for an acceptable ozone test chamber are sufficient air-ozone throughput rate, sufficient internal circulation, and sufficient internal volume. A secondary requirement is that of controlling the temperature within acceptable limits. An acceptable ozone test chamber can be custom-made in a particular laboratory, or one of the commercial manufactured chambers. The ozone test chambers shall conform to the following requirements: (i) The test chamber shall be constructed of a material with minimal reaction to ozone. (ii) The volume of the chamber shall be at least 140 litres and capable of holding the apparatus for mounting the test specimens. (iii) The air-ozone replacement rate or throughput rate must be of a magnitude such that no appreciable reduction in ozone concentration results from the introduction of test specimens. This minimum replacement rate will vary with the ozone concentration, temperature, number of test specimens introduced, and their reaction with ozone. For many chambers operating under normal conditions (approximately 50 parts per 100 000 000), an air-ozone replacement rate of a three-fourths change per minute is an acceptable and adequate value. For thoroughAccessed by UNIVERSITY OF WOLLONGONG on 20 May 2007bAS 1180.7F—November 19722and accurate work, especially under unusual conditions, the minimum or safe replacement rate should be determined.NOTE: Upward concentration adjustments can compensate for a reduction in ozone concentration when specimens are introduced.(iv) A means of providing adequate internal circulation shall be provided. The airozone velocity in the chamber shall be at least 600 mm/s. Where it is doubtful that such velocities exist, the installation of an ordinary 1700 rev/min electric motor and fan blade of approximately 150 mm diameter and 20 to 30 degrees pitch will produce such air velocities. The motor itself shall not be in the chamber. An extension shaft shall be used with an appropriate seal. (v) A means of controlling the temperature of the chamber from ambient to 70°C shall be provided. The temperature regulation should be capable of maintaining the test temperature within ± 1°C. (vi) It is often advantageous to have glass window or front door as part of the chamber. 3.2 Mounting for Test Specimens or Pieces. Mountings for test specimens or pieces shall be as shown in Figs 1 and 2. 3.3 Ozone Generator. A means for generating and controlling an ozone-air stream shall be provided. The generating source shall be located outside the chamber and fed with filtered air drawn directly from the laboratory or from a compressed air supply. The air-ozone stream shall be introduced into the chamber in such a manner that stratification of ozone is prevented.N OTE: The mercury vapour lamp is the most common source for generating ozone. With such a lamp the ozone concentration can be easily controlled by means of a variable transformer. This will transform the voltage fed to the primary of the transformer to that required by the mercury lamp.Accessed by UNIVERSITY OF WOLLONGONG on 20 May 20073.4 Apparatus for Determining Ozone Concentration. 3.4.1 General. Apparatus for measuring the concentration of ozone in the test chamber shall be provided. A satisfactory method is absorption of the ozone in a buffered potassium iodide solution followed by titration of the released iodine with a standard solution of sodium thiosulphate. One of three alternative absorption devices shall be provided, two of which are spray-jet devices and the third a counter-current absorption column. The end point of the titration may be determined by the microammeter method or by the null indicator method described herein. The air sample is drawn directly from the ozone chamber. Special precautions to draw air from various levels of the chamber are not necessary, since adequate circulation will be maintained if the preceding chamber specifications are met. Glass lines only should be used to convey the air-ozone stream to the absorbing device. Plasticized plastics are to be avoided, except as short connecting pieces for joining glass tubing.3AS 1180.7F—November 1972Fig. 1. MOUNTING FOR TEST SPECIMENS—PLAN VIEWFig. 2. MOUNTING FOR TEST SPECIMENS—SIDE ELEVATIONAccessed by UNIVERSITY OF WOLLONGONG on 20 May 20073.4.2 Absorption of ozone. (i) The spray-jet device is shown in Fig. 3. The glass tube, A, is approximately 90 mm in diameter and 100 mm long terminating at B in a short length capillary tubing with a base of 1.0 to 2.0 mm. Concentric within A is a smaller glass tube, C (Fig. 3 (a) is an enlarged view of this part). The end of C is first carefully heated in a blowpipe flame until the bore is reduced in size so as just to admit a wire or drill 0.75 mm in diameter. At this thickened end two flats are ground off on a sheet of fine alumina abrasive paper as at D in Fig. 3 (b). When in position in tube A, end D fits snugly against the hole in capillary B. A rubber tubing connection at E holds the two tubes in position. F is a trap about 50 mm in diameter and 100 mm long, and G is an enlargement in the exit tube about 38 mmAS 1180.7F—November 19724in diameter, containing glass wool to trap spray passing F. F is connected to the side of tube A. H is a 1-litre three-neck Woulff bottle or round-bottom chemically resistant flask in which A and F are secured by standard-taper ground joints, A occupying the centre opening with B protruding just below the neck and J reaching to within 13 mm of the bottom of the bottle. The third opening serves to introduce and remove the reagent. A is connected through plasticized polyvinyl chloride tubing and glass tubing to rotameter graduated from 0 to 1000 litres of air per hour. The entrance to the rotameter is connected with glass tubing to the sampling tube, and the exit of F is connected to a vacuum line. When properly regulated and a vacuum applied at F, most of the reagent enters F, furnishing a head of reagent at B, where the entering air resolves it into a fine mist which fills the entire bottle. The absorption flask shall be mounted in a light-tight box to protect it from light during the time a run is being made.Fig. 3. OZONE ABSORBING DEVICE (SPRAY-JET)Accessed by UNIVERSITY OF WOLLONGONG on 20 May 2007(ii) Modified spray-jet device. A modification of the spray-jet method is in current use on some commercial ozone chambers. This involves absorbing the ozone in a buffered potassium iodide solution which contains a measured amount of5AS 1180.7F—November 1972standard sodium thiosulphate solution. The time for the sodium thiosulphate to be consumed by reaction with iodine is measured. This has the advantage over the unmodified spray-jet method, in that no iodine is volatilized, and no empirical factor is therefore necessary to correct for this loss. To use this modified method, it is necessary to alter slightly the equipment shown in Fig. 3. A round-bottom flask with a bottom drain cock shall be used with four necks or outlets. Two of these are used as depicted in Fig. 3, to house the spray-jet and the upper reservoir return tube, and the other two contain a pair of platinum electrodes and a burette for adding sodium thiosulphate solution. The modified apparatus is shown in Fig. 4.Fig. 4. MODIFIED SPRAY-JET APPARATUSAccessed by UNIVERSITY OF WOLLONGONG on 20 May 2007(iii) Counter-current absorption column. This device absorbs the ozone from the air-ozone stream by providing a large surface area for gas-liquid contact. A buffered solution of potassium iodide percolates down through the column, and this counter-current flow (solution down—air stream up) removes the ozone from the air-ozone stream. Fig. 5 is a diagram for the counter-current column. Such aAS 1180.7F—November 19726column can be fabricated by a qualified glass blower. The column is filled with clean 3 mm glass helices. These must be packed down tightly for efficient operation. Glass beads, 6 mm may be used at the bottom of the column below the inlet to prevent fragments of the helices from entering the stopcock. None of the dimensions on the drawing are critical, but the lower part of the column should be not less than 200 mm. It has been found unnecessary to shield this columnAccessed by UNIVERSITY OF WOLLONGONG on 20 May 2007Fig. 5. COUNTER-CURRENT OZONE ABSORPTION COLUMN7AS 1180.7F—November 1972from artificial lighting. It is not recommended that it be used in direct outdoor light. The advantages of this column over the spray-jet device are (a) the mechanical operation is simpler since no tedious spray adjustments are required, (b) there is no volatilization of iodine since it is carried promptly into the collection flask, and (c) no pressure drop occurs in the analysis apparatus train. Such a pressure drop will cause faulty ozone concentration measurements if a small undetected leak develops. 3.5 Titration Apparatus. Two methods are described for the titration differing only in the means used to determine the end point. The solution and washings from the ozone absorption device may be titrated in a 250 ml wide-mouth flask or a beaker of equal size. A microburette shall be used to deliver the titrant and the solution stirred with an air or magnetic stirrer. (i) Microammeter method. A microammeter of 0-20 range. A heavy duty dry cell of 1 1/2 V. One 1000 ohm and one 30 000 ohm resistor. Two platinum electrodes approximately 2.5 mm in diameter and 25 mm in length, embedded in glass tubing. Connect the resistors in series across the 11/ 2 V battery and apply the potential across the 1 000 ohm resistor to the electrodes. The microammeter is connected in series, with proper consideration for polarity, with the electrodes in this secondary circuit.NOTE: It is possible to use a microammeter with a 0-50 range instead of 0-20, but with a loss of sensitivity.(ii) Null indicator method. A special null meter can be employed that utilizes a onetransistor amplification stage and represents a ten-fold increase in end-point sensitivity. This null meter may be used with any ozone absorption device. The initial reading is taken for the buffered potassium iodide solution with a potential of 100 mV applied to the electrodes. This potential shall be automatically applied by the circuitry in the null meter. 4 REAGENTS. 4.1 Reagents Used for Determination of Ozone Concentration. (i) Reagent grade chemicals and distilled water shall be used in all tests. (ii) Buffer solution. Prepare a 0.025M solution of anhydrous disodium hydrogen phosphate (Na 2HPO4) and a 0.025M solution of anhydrous potassium dihydrogen phosphate (KH 2PO4). To prepare the buffer solution having a pH of 6.7 to 7.1, add 1.5 vol. of 0.025M Na 2HPO4 solution to 1 vol. of 0.025M KH 2PO4 solution. Shake thoroughly. (iii) Potassium iodide (KI). (iv) Sodium thiosulphate solution (0.020N). Prepare a 0.020N sodium thiosulphateAccessed by UNIVERSITY OF WOLLONGONG on 20 May 2007AS 1180.7F—November 19728(Na 2S 2O 3)solution.This may be standardized by using a standard 0.0200N potassium bromate (KBrO 3)solution to oxidize an excess quantity of potassium iodide (KI)in acid solution.Titrate the liberated iodine immediately with the Na 2S 2O 3solution.The titration equipment for the Microammeter Method (Clause 3.5(i))may be used to determine the end point in this titration.Store the prepared 0.020N Na 2S 2O 3solution in a cool dark place.(v)Sodium thiosulphate solution (0.0020N).Prepare 0.0020N Na 2S 2O 3solution foruse in the ozone analysis by diluting the 0.020N solution 10to 1,using a 10-ml pipette and 100-ml volumetric flask.Redeterminations of the normality of the 0.020N N 2S 2O 3solution should be carried out weekly.4.2Determination of Ozone Concentration.4.2.1Absorption of ozone.(i)With spray-jet absorber.Dissolve 15g of KI in 75ml of buffer solution.Addthis to the absorber flask,adjust the jet to produce a fine mist,and turn on the vacuum.Adjust the flow rate to 250to 310litres per hour.Allow the absorption to continue for a specified time.(ii)Modified spray-jet absorber.A sufficient quantity of buffer solution containing15g of potassium iodide is added so that a pool of solution fully immerses the electrodes.The air-ozone stream is drawn through the apparatus.(iii)Counter-current absorption column (see Fig.5).Prepare 150ml of the buffersolution,containing 15g of KI and use part of this to flood and wet the column.Drain the solution out of the column and return to the reservoir R.Keep stopcock 4closed during this operation.N OTES :1.Do not use any type of stopcock grease on the column.The efficient operation of the columndepends upon good contact between the air stream and fully wetted glass helices.If grease is used,the helices will gradually become coated,and efficient air-liquid contact will be lost.Since the column does not cause a sharp pressure drop in the line or analysis train,leaks can be easily prevented by water lubrication of the glass joints of caps I and II when the clamps are used.2.Do not allow any solution or water to enter the inlet tube.If it does enter,dry the tube interiorwith a stream of compressed air before starting any test.Keeping stopcock 4tightly closed will prevent any water from entering the tube.Lubricate ground-glass joints I and II with water and fit both caps in e clamp on joint I.Close stopcock 1and open stopcock 2.Adjust stopcock 5so that approximately 20drops per minute (d.p.m.)of solution are flowing into the column from R.Open stopcock 3,apply the vacuum,open stopcock 4,and start the clock.Adjust the flow rate to 310litres per hour.As e d b y U N I V E R S I T Y O F W O L L O N G O N G o n 20 M a y 2007。
