发布日期：2009-12

标准范围

ISO 2062:2009规定了测定取自筒子的纺织纱线的断裂力和断裂伸长率的方法。给出了四种方法:答:手动；标本直接取自调节包装；B:自动；标本直接取自调节包装；C:手动；在调理后使用松弛的测试绞纱；D:手动；样品在润湿后使用。方法C用于对纱线断裂伸长率有争议的情况。ISO 2062:2009规定了使用恒定试样伸长率(CRE)拉伸测试仪的方法。附件A中涵盖了对现已过时的恒定行驶率(CRT)和恒定装载率(CRL)仪器的测试，供参考，因为认识到这些仪器仍在使用，并且可以通过协议使用。ISO 2062:2009适用于所有类型的纱线，但玻璃、弹性体、芳纶、高分子聚乙烯（HMPE）、超高分子量聚乙烯（UHMPE）、陶瓷和碳纱线以及聚烯烃胶带除外。ISO 2062:2009适用于包装纱线，但也可适用于从织物中提取的纱线，但须经相关方同意。ISO 2062:2009旨在用于纱线的单端（单股）测试。

ISO 2062:2009 specifies methods for the determination of the breaking force and elongation at break of textile yarns taken from packages.Four methods are given:

• A: manual; specimens are taken directly from conditioned packages;
• B: automatic; specimens are taken directly from conditioned packages;
• C: manual; relaxed test skeins are used after conditioning;
• D: manual; specimens are used after wetting.

Method C is used in cases of dispute regarding elongation at break of the yarn.ISO 2062:2009 specifies methods using constant rate of specimen extension (CRE) tensile testers. Testing on the now obsolete constant rate of travel (CRT) and constant rate of loading (CRL) instruments is covered, for information, in Annex A, in recognition of the fact that these instruments are still in use and can be used by agreement.ISO 2062:2009 applies to all types of yarns, except glass, elastomeric, aramid, high molecular polyethylene (HMPE), ultra high molecular polyethylene (UHMPE), ceramic and carbon yarns and polyolefin tape.ISO 2062:2009 is applicable to yarns from packages but can be applied to yarns extracted from fabrics, subject to agreement between the interested parties.ISO 2062:2009 is intended for the single-end (single-strand) testing of yarns.
