from negative to positive.4.Summary of Test Method4.1This test method includes test procedures using speci-men shapes as follows:4.2A razor-nicked crescent specimen(Die A),4.3A razor-nicked crescent specimen with tab ends(Die B), 4.4An unnicked90°angle specimen(Die C),and4.5A specimen described as a trouser tear piece,which is designated as Die T.4.6No correlation of results,one specimen versus another, obtained with any of these specimens is implied as an inherent characteristic of this test method.4.7Also included in this test method is Appendix X1,which describes a modified trouser tear specimen test designated as a constrained path tear test.Refer to Appendix X1for more details on this type of tear test which shows substantial promise for measuring a realistic tear strength that has been shown to be correlated with certain rubber product performance.5.Significance and Use5.1Conventional vulcanized rubbers and thermoplastic elastomers often fail in service applications due to the genera-tion and propagation of a special type of rupture called a tear. This test method measures the resistance to tearing action. 5.2Since tear strength may be affected to a large degree by stress-induced anisotropy(mechanicalfibering)of the rubber as well as by stress distribution,strain rate,and size of specimen,the results obtained in a tear strength test can only be regarded as a measure of the strength under the conditions of that particular test and not necessarily as having any direct relation to service value.The significance of tear testing must be determined on an individual application or product perfor-mance basis.5.3Injection molded thermoplastic elastomers are known to be anisotropic in properties.The tear strength measured in different directions can differ markedly.6.General Principles6.1The test consists of measuring the force required to completely rupture or tear the specified test piece,as a continuation of the cut or nick initially produced in the test piece or,in the case of Die C,completely across the width of the test piece.6.1.1The tearing force is applied by means of a tensile testing machine,operated without interruption at a constant rate of cross-head traverse until the test piece is completely torn.For Die A,B,and C samples,the maximum force achieved is used to calculate the tear strength.For Die T,the mean or median force is most commonly used but other ways of interpreting the data are given in Annex A1.7.Apparatus7.1Testing Machine—The testing machine shall,in gen-eral,conform to the requirements as specified in Test Methods D412.It shall be capable of registering the applied forces within2%of the total force range or capacity during the test while maintaining the specified constant rate of separation of the jaws of5065mm/min for the trouser test piece Die T and 500650mm/min for Die A,B,or C pieces.A low inertia machine having autographic recording of force is essential when using the trouser test,Die T.N OTE1—Inertia(pendulum)type dynamometers are apt to give results that differ one from another because of frictional and inertial effects.A low inertia(electronic or optical transducer)type dynamometer gives results that are free from these effects and is therefore to be preferred.7.2The test may be conducted at elevated temperatures using equipment specified in Test Methods D412.7.3Grips—The machine shall be provided with a type of grip,for example air-actuated grip,that tightens automatically as the tension increases and exerts a uniform pressure across the widened end of the test piece.Each grip shall incorporate a means for positioning so that the test specimens are inserted symmetrically and in axial alignment with the direction of the pull.The depth of insertion shall be such that the test specimen is adequately gripped,within the parallel portion,when testing Die A,B,or C test pieces.Trouser test pieces shall be inserted in the grip in accordance with Fig.1.7.4Specimen Cutting Dies—The specimens for tear resis-tance tests shall be cut out with one of the steel dies conforming to the dimensions shown in Fig.2,the cutting edges of which shall be kept sharp and free of all nicks to avoid leaving ragged edges on the specimens.It is important thatthe FIG.1Trouser Tear TestSpecimenapex of the 90°angle due (Die C)be sharpened to provide asharp corner.Good cutting edges can be obtained by carefulhoning.Care shall be taken that the cut edges are perpendicularto the other surfaces of the specimen and have a minimum ofconcavity.7.5Nick Cutter :7.5.1A sharp razor blade or a sharp knife free of raggededges shall be used for producing a cut or a nick in the Die Aand B specimens.The trouser test piece shall be cut to a depthof 4065mm in the direction indicated.(See Fig.1.)It is important that the last 1mm (approximately)of the cut is made with a razor blade or a sharp knife.7.5.2The essentials of a suitable apparatus for introducing the nick required for the nicked angle or crescent test piece are as follows:7.5.2.1Means shall be provided for clamping the test specimen firmly,especially in the region where the nick is to be introduced.The cutting tool,consisting of a razor blade or similar blade,shall be clamped in a plane perpendicular to the major axis of the test piece,and positioned so as tointroduceFIG.2Dies for Tear TestSpecimensthe nick in the appropriate place.The blade clamping device shall prevent lateral movement and shall befitted in guides to enable the blade to befixed and the test piece arranged to move in an analogous manner.Means shall be provided forfine adjustment of the depth of the nick.The adjustment for the position of the blade holder or the clamped test piece,or both, shall be determined for each blade by cutting one or two preliminary nicks and measuring these with the aid of a microscope.The blade shall be wetted with water or soap solution prior to nicking.7.5.3The slit or nick shall be0.5060.05mm(0.0206 0.002in.)in depth.7.5.4To check that the depth of the nick is within the specified limits,any suitable means may be used,for example, an optical projection apparatus.A convenient arrangement is a microscope giving at least103magnificationfitted with travelling stage suitably illuminated.The eyepiece isfitted with a graticule or crosswire by which to record the travel of the stage and test piece through a distance equal to the depth of the nick.The travel of the stage is calibrated with a stage micrometer.Alternatively,a travelling microscopy may be used.The apparatus shall have an accuracy of measurement of 0.025mm or better.7.5.5Die C and Die T test specimens are not nicked.8.Preparation of Sample8.1Except as may be otherwise specified in this test method,the requirements of Practices D3182and D3183shall be complied with and are made a part of this test method for conventional vulanizer rubber.8.2Thermoplastic elastomer test specimens are prepared from injectioned molded plaques prepared in accordance with procedures described in the specification standard for said thermoplastic elastomers.9.Test Specimens9.1The test specimens shall conform in shape according to Die T in Fig.1or to Die A,B,or C,as shown in Fig.2.N OTE2—Conventional vulcanized rubber and thermoplastic elastomers often exhibit an anisotropic mechanical strength effect that influences their physical properties.The effect may produce a pronounced difference in physical properties.9.2The milling or grain direction of conventional rubber shall be clearly marked on materials to be tested.The usual practice is to test with the grain running the long way of the specimen.Die A,B,and C data so obtained shall be recorded as tear resistance across the grain,and it is assumed that,unless otherwise specified,all Die A,B,and C test specimens are to be prepared in this manner.However,Die T trouser tear samples are also prepared with the mill grain running the long way in the specimen which means the tear is occurring with the grain rather than across it.Where grain effects are significant and are to be evaluated,an additional set of test specimens shall be cut with the grain running across the specimen.Results so obtained shall be recorded as tear strength with the grain for Die A,B,and C and across the grain for Die T trouser tear. N OTE3—Die B has been modified slightly from that described in Method D624–54to conform to that specified in ISO/34.Dies conform-ing to previous Die B configuration may be used.9.3Thermoplastic elastomers shall be tested with the tear direction either parallel or perpendicular to theflow direction of molten material in the injection molded plaque from which the test specimens are die cut.9.4The thickness of the specimen shall be measured in three places across the width of the specimen,near its center, with a micrometer conforming to the description as specified in Practice D3767and the median measurement used in the calculations.One of the measurements shall be at the apex of the slit or the90°angle,as applicable.The thickness of the test specimen should not fall outside the limits of1.3to3.2mm (0.05to0.13in.).It may be necessary to determine the tear strength offinished goods that give specimens outside the above thickness limits.These results may not correlate with results obtained on pieces of standard thickness.10.Number of Test Specimens10.1Three specimens per item shall be tested for tear strength.The value reported shall be the median of those observed.If any individual value deviates more than20% from this median,two additional specimens shall be tested,and the median of allfive specimens shall be reported.10.2Tear testing is inherently a highly variable measure-ment since it has many characteristics of fatigue testing that is known to give widely dispersed test results,frequently with a non-normal distribution.For referee tear testing,the user of this test method is urged to test at leastfive specimens. 11.Time Interval Between Vulcanization and Testing 11.1The minimum time period between vulcanization and testing shall be16h.11.2The maximum allowable time period between nicking and testing shall be24h.12.Conditioning Period for Test Specimens12.1The test pieces of specimens shall be protected from light during the interval between vulcanization and testing.12.2The specimens shall be conditioned,after any prepa-ration as necessary,at a standard laboratory temperature(see Practice D1349)for at least3h before they are cut or nicked. The specimens may be nicked,measured and tested immedi-ately but,if not tested immediately,they shall be kept at236 2°C or2762°C,as the case may be,until tested.If the preparation involves buffing,the interval between buffing and testing shall not exceed72h.The cut or nick shall be made after any aging treatment has been carried out.12.3If the test is to be carried out at a temperature other than a standard laboratory(room)temperature,the test pieces shall be conditioned for a period sufficient to reach temperature equilibrium at the test temperature,immediately prior to testing.This period shall be kept as short as possible in order to avoid aging the rubber.13.Test Temperature13.1Unless otherwise specified,the standard temperature for testing shall be2362°C(73.463.6°F).If the material is affected by moisture,the relative humidity shall be maintained at5065%and the specimen shall be conditioned for at least 24h prior to testing.When testing at some other temperatureisrequired,the temperature specified shall be one of those listed in Practice D1349,and the report shall include a statement of the temperature at which the test was made and the length of time that the specimen was conditioned.Specimens shall be conditioned at least3h when the test temperature is2362°C.14.Test Procedure14.1After conditioning as described in Sections11and12, immediately mount the test piece in the testing machine.Apply a steadily increasing traction force at a rate of separation of the grips of500650mm/min for Die A,B and C type specimens and5065mm/min for trouser test pieces until the test piece is completely ruptured.Record the maximum force for Die A, B and C test pieces.When using the trouser test specimen make a strip-chart or autographic recording of the force throughout the tearing process.(See Annex A1).15.Expression of Results15.1The tear strength T s is given,in kilonewtons per meter of thickness,by the formula:T s5Fd(1)where:F5the maximum force,N,in case of Dies A,B and C,and when using Die T,the mean or median(see Annex A1)force obtained from the recorder or autographic trace,N,calculated in accordance with the annex,andd5the thickness,of the test pieces,mm.15.2When anisotropic effects are evaluated,determine the median and the range of the values for each direction.Express the results to the nearest0.1kN/m.15.3Alternatively the tear strength may be expressed in lbf/in.N OTE4—To convert from lbf/inch to kN/m,multiply by0.175. 16.Report16.1Report the following information:16.1.1Results calculated in accordance with Section15, indicating which tear test specimen or die was used and a reference to this standard.In trouser tear strength testing, Method A or B should be specified,16.1.2All observed and recorded data on which the calcu-lations are based,16.1.3Date of test and date of vulcanization of rubber,if known,16.1.4Test temperature,16.1.5Type of testing machine used,and16.1.6The depth of the nick when using Die A or Die B.17.Precision and Bias417.1This precision and bias section has been prepared in accordance with Practice D4483.Refer to this practice for terminology and other statistical calculation details.17.2A Type1(interlaboratory)precision was evaluated in 1981and another in1988.Test repeatability and reproducibil-ity are short term;a period of a few days separates replicate test results.A test result is the median value,as specified by this method,obtained on three determination(s)or measurement(s).17.3In the1981test program,one material(one rubber compound)was tested in four laboratories on two separate days.In the1983test program,two materials(rubbers)were tested infive laboratories on two separate days.For both programs tests were conducted for Dies B and C.17.4The results of the precision calculations for repeatabil-ity and reproducibility are given in Table1and Table2. 17.5The precision of this test method may be expressed in the format of the following statements which use an appropri-ate value of r,R,(r)or(R),that is,that value to be used in decisions about test results(obtained with the test method). The appropriate value is that value of r or R associated with a mean level in the precision tables closest to the mean level under consideration at any given time,for any given material in routine testing operations.17.6Repeatability—The repeatability,r,of this test method has been established as the appropriate value tabulated in the precision tables.Two single test results,obtained under normal test procedures,that differ by more than this tabulated r(for any given level)must be considered as derived from different or non-identical sample populations.17.7Reproducibility—The reproducibility,R,of this test method has been established as the appropriate value tabulated in the precision tables.Two single test results obtained in two different laboratories,under normal test method procedures, that differ by more than the tabulated R(for any given level) must be considered to have come from different or non-identical sample populations.17.8Repeatability and reproducibility expressed as a per-centage of the mean level,(r)and(R),have equivalent application statements as above for r and R.For the(r)and (R)statements,the difference in the two single test results is expressed as a percentage of the arithmetic mean of the two test results.17.9Bias—In test method terminology,bias is the differ-ence between an average test value and the reference(or true) test property value.Reference values do not exist for this test method since the value(of the test property)is exclusively defined by the test method.Bias,therefore,cannot be deter-mined.17.10For Dies B and C,repeatability,(r),is not good(104The full details and test results of the interlaboratory test program used for this precision section are contained in a Research Report RR:D11-1027obtainable from ASTM headquarters.TABLE1Type1Precision for Dies B and C(1981)A DieAverageValueWithin Laboratories Between Laboratories (kN/m)S r r(r)S R R(R) B81.6 5.1114.517.716.847.658.3 C44.5 3.8410.924.4 4.6913.329.8 AS r5repeatability standard deviation.r5repeatability52.833S r.(r)5relative repeatability,expressed as a percentage of the average value.

created by plotting stress versus grip travel ordisplacement during testing.The similarities in curve shape forsamples cut with Dies A,B,and C allow a simple interpretationwhile the saw-toothed curve generated during the trouser teartest can be interpreted in several different ways.A1.2Curve ShapesA1.2.1The simplistic tear curves generated when pullingsamples cut from Dies A,B,and C are single-event shapes withone maximum force peak at which catastrophic failure of thespecimen occurs.A1.2.2There are two primary types of saw-toothed curveswhich are illustrated in Fig.A1.1.Curve a illustrates acharacteristic tear commonly called “knotty tear”where theword “knotty”designates a large magnitude transient increasein tearing force followed by a precipitous decrease,and the“increase-decrease”process repeats in cyclic fashion.Eachincreasing force stage eventually produces a rapid tear orrupture which relieves concentrated stress and increases tornlength.Just as the maximum force reached before tearing is ameasure of tear strength,the level to which the force decreasesbefore tear ceases also indicates important tear properties of thecompound.A1.2.3Curve b illustrates a typical “smooth tear”curvewith minimal tear force amplitudes between the force at whichtear initiates and the force at which tear ceases.A1.3Method A—Curve AnalysisA1.3.1Terms for Curve Analysis —The terms used for curve analysis are defined in Section 3.A1.3.2Procedure for Die A,B,and C Type Tear Curves —The recorded plot of stress versus displacement for samples cut with Dies A,B,and C shows a sharply positive slope until catastrophic failure occurs,at which point the trace slope turns sharply negative.This produces a peak or maximum force value from which the tear strength is calculated.A1.3.3Procedure for Die T (Trouser Tear)Type Tear Curves —The “max-min”stress/displacement curve produced during the Die T trouser tear test can be interpreted in fourTABLE

Only Analysis:(1)This method examines only the peak forces generated during the tearing process.The value generated defines the maximum stress concentration that the compound will bear before catastrophic failure occurs.(2)The sum of the forces(at each peak)can be divided by the number of peaks to define a mean peak value.(3)In establishing the repetitive pattern of transient tearing that creates the max-min curve,it is not uncommon to have the initial or terminal peaks,or both,be inconsistent in magnitude with those in the center of the curve.Such peaks can be abnormally low or high depending on the physical properties of the compound and how quickly the transient tear pattern is established or ended.Correction is made to eliminate these values in determining the mean by comparing their magnitude to that of the raw mean and discarding all values that deviate from the raw mean by20%or more.What results then is a mean of the significant peak data points.A1.3.3.2Valley Only Analysis:(1)This method examines only the forces at the valley positions on the saw-toothed curve as a measure of the force to which the stress concentration must be relaxed for tearing to cease.(2)As in the mean in the peak only procedure,initial and terminal valley force values are compared to the raw mean calculated by summing the force values at each valley and dividing by the number of data points.Initial or terminal values greater than or equal to20%of this raw mean are discarded and the mean is recalculated.A1.3.3.3Mean Force Analysis:(1)The arithmetic mean of the corrected peak only force value and the corrected valley only force value will yield a mean force value.This should be considered as an average tear force value since it gives equal consideration to peak and valley extremes.Be aware that this value does not indicate the magnitude of the difference between peak and valley forces but only represents the mean force.It is possible for two tear curves to show the same mean force when one has a large magnitude of difference between the peak and valley forces while the other has a small magnitude of difference.(2)The procedure for Method A analysis,which is the most concise,is to report the mean force value with a plus or minus value determined by averaging the greatest four to six peak force values and the lowest four to six valley force values to define the magnitude of variation there is from the mean.A1.3.3.4Total Work Analysis—The total work put into the sample to achieve the tear can be obtained by measuring the area under the force-extension curve.This area can be mea-sured electronically by certain equipment with integration capability or it can be measured manually by the use of a planimeter.This parameter will correlate with the mean force since it gives full consideration to both peak and valley extremes although it will not define the magnitude of variation from the mean.A1.4Method B—Curve AnalysisA1.4.1The terms used for Method B are defined in Section 3.A1.4.2Procedure for a Type Curves(Knotty Tear):A1.4.2.1Count the number of e3.2.7as a defini-tion of the median peak force value.To obtain this median value,locate,with a horizontal line,the lowest or No.1peak force value.Move upward from this line on the force scale,the required number of peak force values to arrive at the median. Scale from the force axis this value.In Fig.A1.1,the lowest (No.1)peak is indicated by the boldface arrow.The median peak is indicated as assessed from the lowest No.1value.A1.4.3Procedure for b Type Curves(Smooth Tear):A1.4.3.1Smooth type tear curves often consist of a series of tear propagation or torn length sequences each at essentially constant tearing force.In Fig.A1.1,Curve b shows two such sequences(1)and(2),with(2)approximately twice the length of(1).The tear strength should be calculated on a weighted average force basis.A1.4.3.2A general formula for weighted average tear force is:Tear Force~Weighted Average!5n o~TF1!1N2~TF2!1···N i~TF i!(~n i!(A1.1) where:n o5smallest observable segment(chart paper distance) for a constant tear force segment,N25n2n o5the weighting factor for constant tearforce(TF)segment TF2,with n2as the actualsegment distance for TF2,and((n i)5sum of all n o values or total torn length or chart paper distance measured in n o units.A1.4.3.3Use this weighted average tear force in Eq1(see 15.1).A1.4.3.4A median force is specified for Annex A1,curve analysis Method B.The median force(for tear strength calculation)is selected for two reasons:(1)it is much easier to obtain than an average,and(2)it does not give undue weight to abnormally large or small peakforces.APPENDIX(Nonmandatory Information)X1.DESCRIPTION OF A CONSTRAINED PATH (CP)TEAR TEST SPECIMENX1.1BackgroundX1.1.1To characterize rubbers adequately,a knowledge oftheir rupture properties is essential.Tear strength is importantin the performance of many rubber products.X1.1.2One reason for the lack of discrimination in manycurrent tear tests is a direct influence of compound modulus onmeasured tear strength.Fig.X1.1is a plot of D624Die C tearstrength as a function of modulus (300%)for data taken fromthe literature.This shows tear strength to be strongly correlatedwith modulus (correlation coefficient of 0.90).Thus bothmodulus and tear strength are being measured in unknownproportions.Theoretical calculations,show that the tear ruptureforce of Die C specimen measurements is approximately equalto the square root of the tangent modulus-tear strength product.X1.1.3It should not be inferred that modulus will have noeffect on tear strength;however,the influence of modulusshould be allowed to operate in the immediate tearing zone andnot in regions of the test specimen remote from the locus oftear.In short,a tear test specimen should not be an ill-shapedmodulus (tensile)test specimen.X1.1.4Rivlin,Thomas,et al.developed tear tests based ontheoretical analysis of crack growth behavior.For flat sheet testspecimens they defined a tearing energy or strength T ,that isindependent of the geometry of the test specimen provided thestored energy density of the specimen could be measured.Three types of test specimens were used:the strip or tensilespecimen,the pure shear specimen and the trousers tearspecimen.The relation for the tearing energy with the trouserspecimen is:T 52l F /t 2wE (X1.1)where:T 5tear strength in force/unit thickness (per unit length torn),l 5extension ratio in legs of piece,F 5force applied to ends of test piece,w 5total width of specimen,t 5thickness,and E 5strain energy density in legs of piece.For certain vulcanizates,if w is chosen large enough,the elongation of the legs is minimal (l [1)and E is essentially zero.Then:T 52F /t (X1.2)X1.1.5Many published reports imply that Eq X1.2is satisfactory to use for routine tear measurements.However,two serious deficiencies are evident:For many compounds there is appreciable leg extension (l fi1)even if w is chosen to be quite wide;and secondly knotty tear is frequently encountered and the tear deviates laterally and tears through one leg of the test specimen.Development of Eq X1.1and Eq X1.2is based on tear propagation down the central axis of the test piece.X1.1.6Leg extension can be allowed for if strain energy density E is known,but a separate stress-strain curve is required.When one leg of the test specimen is torn through,further testing is precluded with that specimen.These deficien-cies very often preclude any quick and meaningful routine tear strength measurement with the simple trousers test piece.X1.1.7In order to avoid these deficiencies,it is necessary to reinforce the legs to prevent their elongation and to provide a path of least resistance for tear propagation.Fig.X1.2gives pertinent details and dimensions of a trousers tear specimen designated as a “constrained path”tear test specimen.It consists of a molded piece 125mm long,28.5mm wide,with a nominal thickness of 5mm.A longitudinal groove with the indicated cross-sectional geometry is molded into the piece.The legs are reinforced with fabric.The fabric is placed at the mid-plane of the piece to avoid an appreciable bending moment and to facilitate its reinforcing action during actual tear testing.The bottom of the mold contains two puncture pins;these puncture and hold the fabric as the mold is closed and prevent a lateral fabric shift.X1.2Test Procedure X1.2.1A 60-mm cut is made down the groove with a razor blade.This produces two legs,each of which is inserted into the jaws of a tensile testing machine.The final length of the specimen is torn at a selected testing speed and temperature.X1.2.2The thickness of the torn rubber is measured inone of two ways:(1)the average total thickness of the test piece along the groove is measured and from this is subtracted 3.60mm,the combined height of the insert sections that formtheN OTE 1—Data
