1、Designation: D5035 11Standard Test Method forBreaking Force and Elongation of Textile Fabrics (StripMethod)1This standard is issued under the fixed designation D5035; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、 revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers raveled strip and cut strip testprocedures for determining the breaking force and elongationof mos
3、t textile fabrics. Provision is made for wet testing.1.1.1 The raveled strip test is applicable to woven fabricswhile the cut strip test is applicable to nonwoven fabrics, feltedfabrics, and dipped or coated fabrics.1.2 This test method is not recommended for knitted fabricsor for other textile fabr

19、nificance and Use5.1 The raveled strip test in this test method is consideredsatisfactory for acceptance testing of commercial shipments ofwoven textile fabrics because the method has been usedextensively in the trade for acceptance testing. The same is truefor the cut strip test for felted or nonwo
20、ven textile fabrics.5.1.1 If there are differences of practical significance be-tween reported test results for two laboratories (or more),comparative test should be performed to determine if there is astatistical bias between them, using competent statistical assis-tance. At a minimum, use the samp
21、les for such a comparativetest that are as homogeneous as possible, drawn from the samelot of material as the samples that resulted in disparate resultsduring initial testing and randomly assigned in equal numbersto each laboratory. The test results from the laboratoriesinvolved should be compared u
22、sing a statistical test forunpaired data, a probability level chosen prior to the testingseries. If bias is found, either its cause must be found andcorrected, or future test results for that material must beadjusted in consideration of the known bias.5.2 The method is not recommended for knitted fa
23、bricsbecause of their high stretch.5.3 Some modification of the techniques may be necessaryfor any fabric having a strength in excess of 200 N/cm (1140lbf/in.) width. Special precautionary measures are provided foruse when necessary with strong fabrics, or fabrics made fromglass fibers (see Specific
24、ation D579), to prevent them fromslipping in the clamps or being damaged as a result of beinggripped in the clamps.5.4 All of the procedures are applicable for testing fabricseither conditioned or wet.5.5 Comparison of results from tensile testing machinesoperating on different principles is not rec
