74HC245详细中文资料

74HC245详细中文资料74HC245是一款高速CMOS器件，74HC2 45引脚兼容低功耗肖特基TTL（LSTTL）系列。

74HC245译码器可接受3位二进制加权地址输入（A0, A1和A2），并当使能时，提供8个互斥的低有效输出（Y0至Y7）。

74HC245特有3个使能输入端：两个低有效（E1和E2）和一个高有效（E3）。

除非E1和E2置低且E3置高，否则74HC138将保持所有输出为高。

利用这种复合使能特性，仅需4片7 4HC245芯片和1个反相器，即可轻松实现并行扩展，组合成为一个1-32（5线到32线）译码器。

任选一个低有效使能输入端作为数据输入，而把其余的使能输入端作为选通端，则74HC245亦可充当一个8输出多路分配器，未使用的使能输入端必须保持绑定在各自合适的高有效或低有效状态。

74HC245与74HC 238逻辑功能一致，只不过74HC138为反相输出。

功能CD74HC245 ，CD74HC238和CD74HCT245， CD74HCT238是高速硅栅CMO S解码器，适合内存地址解码或数据路由应用。

74HC245作用原理于高性能的存贮译码或要求传输延迟时间短的数据传输系统,在高性能存贮器系统中,用这种译码器可以提高译码系统的效率。

将快速赋能电路用于高速存贮器时,译码器的延迟时间和存贮器的赋能时间通常小于存贮器的典型存取时间,这就是说由肖特基钳位的系统译码器所引起的有效系统延迟可以忽略不计。

HC138 按照三位二进制输入码和赋能输入条件,从8 个输出端中译出一个低电平输出。

两个低电平有效的赋能输入端和一个高电平有效的赋能输入端减少了扩展所需要的外接门或倒相器,扩展成24 线译码器不需外接门;扩展成32 线译码器,只需要接一个外接倒相器。

在解调器应用中,赋能输入端可用作数据输入端。

特性复合使能输入，轻松实现扩展兼容JEDEC标准no.7A 存储器芯片译码选择的理想选择低有效互斥输出 ESD保护 HBM EIA/JESD22-A114-C超过2000 V MM EIA/JESD22-A115-A超过200 V 温度范围 -40～+85 ℃ -40～+125 ℃多路分配功能74HC245是一款高速CMOS器件，74HC245引脚兼容低功耗肖特基T TL（LSTTL）系列。

Compared to standard 2 Watt packages, space savings of 80% and 77% respectively are achieved by these RTS & RTD 2 Watts SMD-Miniature DC/DC Converters. They have been specifically designed for applications where board space is at a premium since these 2 Watt converters have only a slightly larger foot print than conventional 1 Watt converters. With efficiencies up to 85%, external cooling is not needed, as the full output power is available over the operating temperature range -40°C to +85°C. All converters have an I/O-Isolation of 1kVDC, or optionally 3kV, making them suitable for many applications.

ASTM D 2240-2005

Designation:D2240–05Standard Test Method forRubber Property—Durometer Hardness1This standard is issued under theﬁxed designation D2240;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1This test method covers twelve types of rubber hardness measurement devices known as durometers:Types A,B,C,D, DO,E,M,O,OO,OOO,OOO-S,and R.The procedure for determining indentation hardness of substances classiﬁed as thermoplastic elastomers,vulcanized(thermoset)rubber,elas-tomeric materials,cellular materials,gel-like materials,and some plastics is also described.1.2This test method is not equivalent to other indentation hardness methods and instrument types,speciﬁcally those described in Test Method D1415.1.3This test method is not applicable to the testing of coated fabrics.1.4All materials,instruments,or equipment used for the determination of mass,force,or dimension shall have trace-ability to the National Institute for Standards and Technology, or other internationally recognized organizations parallel in nature.1.5The values stated in SI units are to be regarded as standard.The values given in parentheses are for information only.Many of the stated dimensions in SI are direct conver-sions from the U.S.Customary System to accommodate the instrumentation,practices,and procedures that existed prior to the Metric Conversion Act of1975.1.6This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1ASTM Standards:2D374Test Methods for Thickness of Solid Electrical Insu-lationD618Practice for Conditioning Plastics for TestingD785Test Method for

Requirements for the Com-petence of Testing and Calibration Laboratories3.Summary of Test Method3.1This test method permits hardness measurements based on either initial indentation or indentation after a speciﬁed period of time,or both.Durometers with maximum reading indicators used to determine maximum hardness values of a material may yield lower hardness when the maximum indi-cator is used.3.2The procedures for Type M,or micro hardness durom-eters,accommodate specimens that are,by their dimensions or conﬁguration,ordinarily unable to have their durometer hard-ness determined by the other durometer types described.Type M durometers are intended for the testing of specimens having a thickness or cross-sectional diameter of1.25mm(0.050in.) or greater,although specimens of lesser dimensions may be successfully accommodated under the conditions speciﬁed in Section6,and have a Type M durometer hardness range between20and90.Those specimens which have a durometer hardness range other than speciﬁed shall use another suitable procedure for determining durometer hardness.4.Signiﬁcance and Use4.1This test method is based on the penetration of a speciﬁc type of indentor when forced into the material under speciﬁed conditions.The indentation hardness is inversely related to the penetration and is dependent on the elastic modulus and viscoelastic behavior of the material.The geometry of the1This test method is under the jurisdiction of ASTM Committee D11on Rubber and is the direct responsibility of Subcommittee D11.10on Physical Testing.Current edition approved Aug.15,2005.Published September2005.Originally approved st previous edition approved in2004as D2240–04e1.2For referenced ASTM standards,visit the ASTM website,,or contact ASTM Customer

the applied force inﬂuence the measurements such that no simple relationship exists between the measure-ments obtained with one type of durometer and those obtained with another type of durometer or other instruments used for measuring hardness .This test method is an empirical test intended primarily for control purposes.No simple relationship exists between indentation hardness determined by this test method and any fundamental property of the material tested.For speciﬁcation purposes,it is recommended that Test Method D 785be used for materials other than those described in 1.1.5.Apparatus5.1Hardness Measuring Apparatus,or Durometer,and an Operating Stand ,Type 1,Type 2,or Type 3(see 5.1.2)consisting of the following components:5.1.1Durometer :5.1.1.1Presser Foot ,the conﬁguration and the total area of a durometer presser foot may produce varying results when there are signiﬁcant differences between them.It is recom-mended that when comparing durometer hardness determina-tions of the same type (see 4.1),that the comparisons be between durometers of similar presser foot conﬁgurations and total area,and that the presser foot conﬁguration and size be noted in the Hardness Measurement Report (see 10.2.4and 5.1.1.3).5.1.1.2Presser Foot ,Types A,B,C,D,DO,E,O,OO,OOO,and OOO-S,with an oriﬁce (to allow for the protrusion of the indentor)having a diameter as

attained,however,this effect is greater on durometers of lesser total mainspring loads;for example,the effect of a maximum indicating pointer on Type D durometer determinations will be less than those determinations achieved using a Type A durometer.Analog style durometers may be equipped with maximum indicating pointers.The effect of a maximum indicating pointer shall be noted at the time of calibration in the calibration report (see 10.1.5),and when reporting hardness determinations (see 10.2.4).Analog Type M,OO,OOO,and Type OOO-S durometers shall not be equipped with maximum indicating pointers.5.1.1.12Digital electronic durometers may be equipped with electronic maximum indicators that shall not affect the indicated reading or determinations attained by more than one half of the spring calibration tolerance stated in Table 1.5.1.1.13Calibrated Spring ,for applying force to the inden-tor,in accordance with Fig.1(a through g)and capable of applying the forces as speciﬁed in Table 1.5.1.2Operating Stand (Fig.2):5.1.2.1Type 1,Type 2,and Type 3shall be capable of supporting the durometer presser foot surface parallel to the specimen support table (Fig.3)throughout the travel of each.The durometer presser foot to specimen support table parallel-ism shall be veriﬁed each time the test specimen support table is adjusted to accommodate specimens of varying dimensions.This may be accomplished by applying the durometer presser foot to the point of contact with the specimen support table and making adjustments by way of the durometer mounting assem-bly or as speciﬁed by the manufacturer.5.1.2.2Operating Stand,Type 1(specimen to indentor type),shall be capable of applying the specimen to the indentor in a manner that minimizes shock.5.1.2.3Operating Stand,Type 2(indentor to specimen type),shall be capable of controlling the rate of descent of the indentor to the specimen at a maximum of 3.20mm/s(0.125FIG.1(e)Type OOO

specimen type),hydraulic dampening,pneumatic dampening,or electro-mechanical (required for the operation of Type M durometers)shall be capable of controlling the rate of descent of the indentor to the specimen at a maximum of 3.2mm/s (0.125in./s)and applying a force sufficient to overcome the calibrated spring force as shown in Table 1.Manual application,Type 1or Type 2operating stands are not acceptable for Type M durometer operation.5.1.2.5The entire instrument should be plumb and level,and resting on a surface that will minimize vibration.Operating the instrument under adverse conditions will negatively affect the determinations attained.5.1.2.6Specimen Support Table ,(Fig.3)integral to the operating stand,and having a solid ﬂat surface.The specimen support platform may have oriﬁces designed to accept various inserts or support ﬁxtures (Fig.3)to provide for the support of irregularly conﬁgured specimens.When inserts are used to support test specimens,care must be taken to align the indentor to the center of the insert,or the point at which the indentor is to contact the specimen.Care should be exercised to assure thatthe indentor does not abruptly contact the specimen support table as damage to the indentor may result.6.Test Specimen6.1The test specimen,herein referred to as “specimen”or “test specimen”interchangeably,shall be at least 6.0mm (0.24in.)in thickness unless it is known that results equivalent to the 6.0-mm (0.24-in.)values are obtained with a thinner specimen.6.1.1A specimen may be composed of plied pieces to obtain the necessary thickness,but determinations made on such specimens may not agree with those made on solid specimens,as the surfaces of the plied specimens may not be in complete contact.The lateral dimensions of the specimen shall be sufficient to permit measurements at least 12.0mm (0.48in.)from any edge,unless it is known that identical results are obtained when measurements are made at a lesser distance from an edge.6.1.2The surfaces of the specimen shall be ﬂat and parallel over an area to permit the presser foot to contact the specimen over an area having a radius of at least 6.0mm (0.24in.)from the indentor point.The specimen shall be suitably supported to provide for positioning and stability.A suitablehardnessFIG.1(g)Type E Indentor (continued)TABLE 1Durometer Spring Force Calibration AAll

obtained with a thinner specimen.6.2.1A Type M specimen that is not of a conﬁguration described in 6.2.2may be composed of plied pieces toobtainFIG.2Durometer OperatingStandFIG.3Small Specimen SupportTablethe necessary thickness,but determinations made on such specimens may not agree with those made on solid specimens because the surfaces of the plied specimens may not be in complete contact.The lateral dimensions of the specimen should be sufficient to permit measurements at least 2.50mm (0.10in.)from any edge unless it is known that identical results are obtained when measurements are made at lesser distance from an edge.A suitable hardness determination cannot be made on an uneven or rough point of contact with the indentor.6.2.2The Type M specimen,when conﬁgured as an o-ring,circular band,or other irregular shape shall be at least 1.25mm (0.05in.)in cross-sectional diameter,unless it is known that results equivalent to the 1.25-mm (0.05-in.)values are obtained with a thinner specimen.The specimen shall be suitably supported in a ﬁxture (Fig.3)to provide for positioning and stability.6.3The minimum requirement for the thickness of the specimen is dependent on the extent of penetration of the indentor into the specimen;for example,thinner specimens may be used for materials having higher hardness values.The minimum distance from the edge at which measurements may be made likewise decreases as the hardness increases.7.Calibration7.1Indentor Extension Adjustment Procedure :7.1.1Place precision ground dimensional blocks (Grade B or better)on the support table and beneath the durometer presser foot and indentor.Arrange the blocks so that the durometer presser foot contacts the larger block(s)and the indentor tip just contacts the smaller block (Fig.4).It is necessary to observe the arrangement of the blocks and the presser foot/indentor under a minimum of 203magniﬁcation to assure proper alignment.7.1.2Indentor extension and shape shall be in accordance with 5.1.1.5,5.1.1.6,or 5.1.1.7,respective to durometer type.See Fig.1(a through g).Examination of the indentor under 203magniﬁcation,503for Type M indentors,is required to examine the indentor condition.Misshapen or damaged inden-tors shall be replaced.7.1.3A combination of dimensional gage blocks shall be used to achieve a difference of 2.54+0.00/–0.0254mm (0.100+0.00/–0.001in.)between them.For Type OOO-S durometers,the gage block dimensions are 5.08+0.00/–0.0508mm (0.200+0.00/–0.002in.).For Type M durometers,the gage blockdimensions are 1.27+0.0/–0.0127mm (0.050+0.00/–0.0005in.)between them (Fig.4).7.1.4Carefully lower the durometer presser foot until it contacts the largest dimensional block(s),the indentor tip should just contact the smaller block,verifying full indentor extension.7.1.5Adjust the indentor extension to 2.5060.04mm (0.09860.002in.).For Type OOO-S durometers,adjust the indentor extension to 5.060.04mm (0.19860.002in.).For Type M durometers,adjust the indentor extension to 1.2560.02mm (0.04960.001in.),following the manufacturer’s recommended procedure.7.1.5.1When performing the procedures in 7.1,care should be used so as not to cause damage to the indentor tip.Fig.4depicts a suitable arrangement for gaging indentor extension.7.1.6Parallelism of the durometer presser foot to the support surface,and hence the dimensional gage blocks,at the time of instrument calibration,may be in accordance with Test Methods D 374,Machinist’s Micrometers,or otherwise ac-complished in accordance with the procedures speciﬁed by the manufacturer.7.2Indentor Display Adjustment :7.2.1After adjusting the indentor extension as indicated in 7.1,use a similar arrangement of dimensional gage blocks to verify the linear relationship between indentor travel and indicated display at two points:0and 100.Following the manufacturer’s recommendations,make adjustments so that:7.2.2The indicator displays a value equal to the indentor travel measured to within:–0.0+1.0durometer units measured at 0;60.50durometer units measured at 100;61durometer units at all other points delineated in 7.4.7.2.3Each durometer point indicated is equal to 0.025mm (0.001in.)of indentor travel,except for:7.2.3.1Type M Durometers,each indicated point is equal to 0.0125mm (0.0005in.)of indentor travel;7.2.3.2Type OOO-S Durometers,each indicated point is equal to 0.050mm (0.002in.)of indentor travel.7.2.4The indicator shall not display a value greater than 100or less than 0at the time of calibration.7.2.5Other means of determining indentor extension or indentor travel,such as optical or laser measurement methods,are acceptable.The instrumentation used shall have traceability as described in 1.4.7.2.6The durometer shall be supported in a suitable fashion when performing the procedures described in 7.1and 7.2.7.3Calibration Device :7.3.1The durometer spring shall be calibrated by support-ing the durometer in a calibrating device,see Fig.5,in a vertical position and applying a measurable force to the indentor tip.The force may be measured by means of a balance as depicted in Fig.5,or an electronic force cell.The calibrating device shall be capable of measuring applied force to within 0.5%of the maximum spring force necessary to achieve 100durometer units.7.3.2Care should be taken to ensure that the force is applied vertically to the indentor tip,as lateral force will cause errors in calibration.See 7.1.5.1and 7.1.6.FIG.4Detail of Indentor Extension and DisplayAdjustment7.4Spring Calibration —The durometer spring shall be calibrated at displayed readings of 10,20,30,40,50,60,70,80,and 90.The measured force (9.83mass in kilograms)shall be within the spring calibration tolerance speciﬁed in Table 1.Table 1identiﬁes the measured force applied to the indentor for the entire range of the instrument,although it is necessary only to verify the spring calibration at points listed herein.7.5Spring Calibration Procedure :7.5.1Ensure that the indentor extension has been adjusted in accordance with 7.1,and the linear relationship between indentor travel and display is as speciﬁed in 7.2.7.5.2Place the durometer in the calibration device as depicted in Fig.5.Apply the forces indicated in Table 1so that forces applied are aligned with the centerline of the indentor in a fashion that eliminates shock or vibration and adjust the durometer according to manufacturers’recommendations so that:7.5.3At the points enumerated in 7.4,the display shall indicate a value equal to 0.025mm (0.001in.)of indentor travel.For Type OOO-S durometers,the display shall indicate a value equal to 0.05mm (0.002in.)of indentor travel.For Type M durometers,the display shall indicate a value equal to 0.0125mm (0.0005in.)of indentor travel within the spring calibration tolerances speciﬁed in 7.6.7.6Spring calibration tolerances are 61.0durometer units for Types A,B,C,D,E,O,and DO,62.0durometer units for Types OO,OOO,and OOO-S,and 64.0durometer units for Type M,while not indicating below 0or above 100at the time of calibration (see Table 1).7.7Spring Force Combinations :7.7.1For Type A,B,E,and O durometers:Force,N =0.55+0.075HAWhere HA =hardness reading on Type A,B,E,and O durometers.7.7.2For Type C,D,and DO durometers:Force,N =0.4445HDWhere HD =hardness reading on Type C,D,and DO durometers.7.7.3For Type M durometers:Force,N =0.324+0.0044HMWhere HM =hardness reading on Type M durometers.7.7.4For Type OO and OOO durometers:Force,N =0.203+0.00908HOOWhere HOO =hardness reading on Type OO durometers.7.7.5For Type OOO-S durometers:Force,N =0.167+0.01765HOOO-SWhere HOOO-S =hardness reading on Type OOO-S durometers.7.8The rubber reference block(s)provided for verifying durometer operation and state of calibration are not to be relied upon as calibration standards.The calibration procedures outlined in Section 7are the only valid calibration procedures.7.8.1The use of metal reference blocks is no longer recommended (see Note 2).7.9Verifying the state of durometer calibration,during routine use ,may be accomplished by:7.9.1Verifying that the zero reading is no more than 1indicated point above zero,and not below zero (on durometers so equipped),when the durometer is positioned so that no external force is placed upon the indentor.7.9.2Verifying that the 100reading is no more than 100and no less than 99when the durometer is positioned on a ﬂat surface of a non-metallic material so that the presser foot is in complete contact,causing the indentor to be fully retracted.7.9.2.1It is important that when performing the veriﬁcation of 100,as described in 7.9.2,that extreme care be taken so as to not cause damage to the indentor.Veriﬁcation of the 100value is not recommended for durometers having a spring force greater than 10N (Types C,D,and DO).7.9.2.2When performing the veriﬁcation of 100,as de-scribed in 7.9.2,the non-metallic material shall be of a hardness value greater than 100of the type (scale)of the durometer being employed.Tempered glass of a thickness greater than 6.35mm (0.25in.)has been found satisfactory for this application.7.9.3Verifying the displayed reading at any other point using commercially available rubber reference blocks which are certiﬁed to a stated value of the type (scale)of the durometer being employed.The displayed value of the durom-eter should be within 62durometer points of the reference block’s stated value.7.9.4Veriﬁcation of the zero and 100readings of a durom-eter provide reasonable assurance that the linear relationship between the indicated display and the durometer mechanism remain valid.7.9.5Veriﬁcation of points between zero and 100provide reasonable assurance that the curvilinear relationship between the indicated display and the durometer mechanism remain valid.7.9.6This is not a calibration procedure,it is a means by which a user may routinely verify that the durometer may be functioning correctly.(See Note 2.)boratory Atmosphere and Test Specimen Conditioning8.1Tests shall be conducted in the standard laboratory atmosphere,as deﬁned in Practice D 618,Section 4.2.8.2The instrument shall be maintained in the standard laboratory atmosphere,as deﬁned in Practice D 618,Section 4.1,for 12h prior to performing atest.FIG.5Example of Durometer CalibrationApparatus8.3The specimen shall be conditioned in accordance with condition40/23exclusive of humidity control,as described in Practice D618,Section8.1,Procedure A and tested under the same conditions,exclusive of humidity control.8.4These procedures may be modiﬁed if agreed upon between laboratories or between supplier and user and are in accordance with alternative procedures identiﬁed in Practice D618.8.5No conclusive evaluation has been made on durometers at temperatures other than23.06 2.0°C(73.46 3.6°F). Conditioning at temperatures other than the above may show changes in calibration.Durometer use at temperatures other than the above should be decided locally(see Practice D1349).9.Procedure9.1Operating Stand Operation(Type3Operating Stand Required for Type M):9.1.1Care shall be exercised to minimize the exposure of the instrument to environmental conditions that are adverse to the performance of the instrument,or adversely affect test results.9.1.2Adjust the presser foot to support table parallelism as described in5.1.2.1.It is necessary to make this adjustment each time the support table is moved to accommodate speci-mens of varying dimensions.9.1.3Prior to conducting a test,adjust the vertical distance from the presser foot to the contact surface of the test specimen to25.462.5mm(1.0060.100in.),unless it is known that identical results are obtained with presser foot at a greater or lesser vertical distance from the test specimen contact surface, or if otherwise stipulated by the manufacturer.9.1.4Place the specimen on the specimen support table,ina manner that the contact point of the indentor is in accordance with Section6,unless it is known that identical results are obtained when measurements are made with the indentor at a lesser distance from the edge of the test specimen.9.1.5Actuate the release lever(Fig.2)of the operating stand or activate the electromechanical device,allowing the durometer to descend at a controlled rate and apply the presser foot to the specimen in accordance with5.1.2.In the case of “specimen to indentor”type operating stands,operate the lever or other mechanism to apply the specimen to the indentor in a manner that assures parallel contact of the specimen to the durometer presser foot without shock and with just sufficient force to overcome the calibrated spring force as shown in Table 1.9.1.6An operating stand that applies the mass at a con-trolled rate of descent,without shock is mandatory for Type M durometers.Hand-held application or the use of a Type1or Type2operating stand for the Type M durometer is not an acceptable practice,see5.1.2.4.9.1.7For any material covered in1.1,once the presser foot is in contact with the specimen,for example,when the initial indentor travel has ceased,the maximum indicated reading shall be recorded.The time interval of1s,between initial indentor travel cessation and the recording of the indicated reading,shall be considered standard.Other time intervals, when agreed upon among laboratories or between supplier and user,may be used and reported accordingly.The indicated hardness reading may change with time.9.1.7.1If the durometer is equipped with an electronic maximum indicator or timing device(refer to5.1.1.9)the indicated reading shall be recorded within160.3s of the cessation of indentor travel and reported(refer to10.2.9for reporting protocols),unless otherwise noted.9.1.7.2If the durometer is equipped with an analog type maximum indicator(refer to5.1.1.10),the maximum indicated reading may be recorded and shall be reported(refer to10.2.9), unless otherwise noted.9.1.7.3If the durometer is not equipped with the devices described in5.1.1.9or5.1.1.10,the indicated reading shall be recorded within1s as is possible and reported(refer to10.2.9), unless otherwise noted.9.1.8Makeﬁve determinations of hardness at different positions on the specimen at least6.0mm(0.24in.)apart,0.80 mm(0.030in.)apart for Type M;and calculate the arithmetic mean,or alternatively calculate the median.The means of calculating the determinations shall be reported according to 10.2.89.2Manual(Hand Held)Operation of Durometer:9.2.1Care shall be exercised to minimize the exposure of the instrument to environmental conditions that are adverse to the performance of the instrument,or adversely affect test results.9.2.2Place the specimen on aﬂat,hard,horizontal surface. Hold the durometer in a vertical position with the indentor tip at a distance from any edge of the specimen as described in Section6,unless it is known that identical results are obtained when measurements are made with the indentor at a lesser distance.9.2.3Apply the presser foot to the specimen,maintaining it in a vertical position keeping the presser foot parallel to the specimen,with aﬁrm smooth downward action that will avoid shock,rolling of the presser foot over the specimen,or the application of lateral force.Apply sufficient pressure to assure ﬁrm contact between the presser foot and the specimen.9.2.4For any material covered in1.1,after the presser foot is in contact with the specimen,the indicated reading shall be recorded within160.1s,or after any period of time agreed upon among laboratories or between supplier and user.If the durometer is equipped with a maximum indicator,the maxi-mum indicated reading shall be recorded within160.1s of the cessation of initial indentor travel.The indicated hardness reading may change with time.9.2.5Makeﬁve determinations of hardness at different positions on the specimen at least6.0mm(0.24in.)apart and calculate the arithmetic mean,or alternatively calculate the median.The means of calculating the determinations shall be reported according to10.2.8.9.3It is acknowledged that durometer readings below20or above90are not considered reliable.It is suggested that readings in these ranges not be recorded.9.4Manual operation(handheld)of a durometer will cause variations in the results attained.Improved repeatability may be obtained by using a mass,securely affixed to the durometer and centered on the axis of the indentor.Recommendedmasses。
