纺织纤维——单纤维断裂强力和断裂伸长率的测定

[中文适用范围]： 本文件规定了测定单根纤维在调节或湿润状态下的断裂力和断裂伸长率的测试方法和条件。 当在不同类型的测试设备上进行这些纤维特性的测定时，通常不会给出相同的结果。 为了避免这种差异，本文件限制使用恒定延伸率测试机。 它适用于所有光纤，包括卷曲光纤，前提是可用光纤的长度能够达到本文件中指定的标距长度。 注：对于天然纤维（尤其是羊毛和棉花），最常进行的断裂试验是纤维束的断裂试验（参见 ISO 3060 和 IWTO 32-82）。 [外文原描述]： This document specifies the method and conditions of test for the determination of the breaking force and elongation at break of individual fibres in the conditioned or wet state. The determination of these fibre properties, when carried out on different kinds of testing equipment, will not generally give identical results. To avoid such differences, this document is restricted to the use of constant-rate-of-extension testing machine. It is applicable to all fibres, including crimped fibres, provided that the length of fibre available enables the gauge length specified in this document. NOTE For natural fibres (especially wool and cotton), the breaking test most commonly performed is that of bundles of fibres (see ISO 3060 and IWTO 32‑82).
