17、 The uses and significance of particular properties andtest methods are discussed in the appropriate sections of thespecified test methods.5. Test Methods (see Note 1)5.1 Breaking StrengthDetermine the breaking strength asdirected in Test Method D5034, using a constant rate ofextension (CRE) tensile
18、 testing machine.NOTE 2If preferred, the use of a constant rate of traverse (CRT)tensile testing machine is permitted. There may be no overall correlationbetween the results obtained with the CRT machine and the CRE machine.Consequently, these two breaking force testers can not be used inter-changea

There may be no overallcorrelation between the results obtained with the tongue tear method (TestMethod D2261) and the Elmendorf machine (D1424). Consequently, thesetwo tear testers cannot be used interchangeably. In the case
21、 of controversy,Test Method D1424 shall prevail.5.4 Dimensional Change:5.4.1 Pressing and Finishing During GarmentManufacturingDetermine the dimensional change duringpressing and finishing as directed in AATCC Method 135.5.4.2 LaunderingDetermine the dimensional change afterlaundering as directed in
