光纤电缆 第1-209部分：通用规范 基本光缆测试程序 环境试验方法 老化 方法 F9

[中文适用范围]： 本部分 IEC 60794-1 定义了用于建立统一环境性能要求的测试程序，适用于： • 与电信设备和采用类似技术的设备一起使用的光缆；以及 • 同时包含光纤和电导体的电缆。 在本文件中，“光缆”一词也可以包括光纤单元、微管光纤单元等。 本文件定义了一个测试标准，通过高温暴露和温度循环来确定电缆的老化性能，以模拟电缆衰减或物理特性的寿命行为。 有关所有类型测试方法的参考指南以及一般要求和定义，请参见 IEC 60794-1-2。 [外文原描述]： IEC 60794-1-209:2024 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. This document defines a test standard to determine cable aging performance by high temperature exposure and temperature cycling in order to simulate lifetime behaviour of the attenuation of cables, or physical attributes. See IEC 60794‑1‑2 for a reference guide to test methods of all types and for general requirements and definitions. This document partially cancels and replaces IEC 60794‑1‑22:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794‑1‑22:2017: a) the ambient temperature test condition has been defined as per IEC 60794‑1‑2; b) all the maximum allowable attenuation increase values for single-mode and multimode fibres have been deleted, and have been included in the list of details to be specified.
