标准范围

本文件规定了在双轴试验机上使用抓取法测定纺织品机织物的最大力和最大力伸长率的程序。该方法主要适用于机织纺织织物，包括表现出由弹性体纤维的存在、机械或化学处理赋予的拉伸特性的织物。它可以适用于通过其他技术生产的织物。它不适用于土工织物[4]、非织造布[3]、涂层织物[5]、纺织玻璃机织物[2]以及由碳纤维或聚烯烃胶带纱线制成的织物。该方法仅限于使用相同轴的恒定延伸率（CRE）试验机。

This document specifies a procedure to determine the maximum force and elongation at maximum force of textiles woven fabrics using a grab method in the biaxial testing machine.The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical, or chemical treatment. It can be applicable to fabrics produced by other techniques. It is not applicable to geotextiles^[4], nonwovens^[3], coated fabrics^[5], textile-glass woven fabrics^[2], and fabrics made from carbon fibres or polyolefin tape yarns.The method is restricted to the use of constant rate of extension (CRE) testing machines to the same axis.
