光缆 - 第 1-311 部分：通用规范 - 光缆基本测试程序 - 光缆元件测试方法 - 光缆元件的拉伸强度和伸长率测试 方法 G11A

[中文适用范围]： 该标准适用于通用光纤电缆规范，具体包括基本光学电缆测试程序和电缆元件测试方法。具体内容涉及对电缆元件的拉力强度与延伸度测试，方法G11A。 [外文原描述]： IEC 60794-1-311:2024 describes test procedures to be used in establishing uniform requirements of optical fibre cable elements for the mechanical property – tensile strength and elongation at break. This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. This document partially cancels and replaces IEC 60794-1-23:2019. This edition includes the following significant technical changes with respect to IEC 60794‑1‑23:2019: a) The information about dumb-bells is removed because this is not used for testing cable elements; b) the parameters strain at yield and E modulus are added in 5.7.
