标准编号:ISO 9073-18:2023

中文名称:非织造布 试验方法 第18部分:用抓取拉伸试验测定拉伸强度和断裂伸长率

英文名称:Nonwovens — Test methods — Part 18: Determination of tensile strength and elongation at break using the grab tensile test

发布日期:2023-11

标准范围

本文件规定了在调节或湿状态下使用抓取法测定非织造布断裂力的测试方法。本试验方法不适用于具有高拉伸百分比的材料。比较基于不同原理运行的拉伸试验机的试验结果是不适用的。本文件规定了使用恒定试样伸长率(CRE)拉伸测试仪的方法。恒定负载率(CRL)仪器在ISO 2062:2009附录?A、认识到这些文书仍在使用,可以通过协议使用。

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.
