标准摘要
[中文适用范围]： 本文件规定了一种在调节或湿润状态下使用抓取法测定无纺布断裂力的测试方法。该测试方法不适用于具有高拉伸率的材料。不适用于比较基于不同原理的拉伸试验机的测试结果。本文件规定了使用恒定速率试样拉伸 (CRE) 拉伸试验机的方法。ISO 2062:2009 附件 A 涵盖了恒定速率加载 (CRL) 仪器，以供参考，因为这些仪器仍在使用，并且可以根据协议使用。 [外文原描述]： 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.
