Nonwovens — Test methods — Part 18: Determination of tensile strength and elongation at break using the grab tensile test
非织造布试验方法第18部分:用抓握拉伸试验测定拉伸强度和断裂伸长率
This document specifies a test method for the determination of the breaking force of nonwovens using a grab method in conditioned or wet state.
This test method is not applicable to materials which have a high percentage of stretch. Comparing test results from tensile testing machines operating on different principles is not applicable.
This document specifies methods using constant rate of specimen extension (CRE) tensile testers. Constant-rate-of-loading (CRL) instruments is covered, for information, in ISO 2062:2009, Annex A, in recognition of the fact that these instruments are still in use and can be used by agreement.
