在规定长度和宽度的试件上以恒定延伸率纵向施加力。根据记录的力-伸长率曲线确定断裂强度和伸长率值。为了满足非织造布的特殊需求，ISO 9073本部分规定了ISO 5081中列出的替代要求。这些是:a）不同的采样程序；b） 恒定延伸率（100毫米/分钟）。

This document specifies a test method for the determination of the breaking force and elongation of nonwovens using a strip method in conditioned or wet state. This test method describes two procedures, Option A (width of test specimen: 25 mm) and Option B (width of test specimen: 50 mm). 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.
