光缆.第1-22部分:总规范.基本光缆试验规程.环境试验方法

[中文适用范围]： IEC 60794 的这一部分定义了用于建立与电信设备和采用类似技术的装置一起使用的光纤电缆环境性能统一要求的测试程序；具有光纤和电导体组合的电缆。在本文件中，“光缆”一词还可以包括光纤单元、微管光纤单元等。有关所有类型测试方法的参考指南以及一般要求和定义，请参阅 IEC 60794-1-2。 [外文原描述]： IEC 60794-1-22:2017 defines test procedures to be used in establishing uniform requirements for the environmental performance of: - optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and - cables having a combination of both optical fibres and electrical conductors. Throughout this document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements and definitions. This second edition cancels and replaces the first edition published in 2012. It constitutes a technical revision. This second edition includes the following significant technical changes with respect to the previous edition: - new test method designation F16 – Compound flow (drip) [E14 in IEC 60794-1-21]; - new test method F17 – Cable shrinkage test (fibre protrusion); - new test method F18 – Mid-span temperature cycling test.
