光纤电缆 第1-201部分：通用规范 基本光缆测试程序 环境试验方法 温度循环 方法 F1

[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： • 与电信设备及采用类似技术的设备一起使用的光缆； • 同时包含光纤和电导体的组合电缆。 本文件中，“光缆”一词也可包括光纤单元、微管光纤单元等。 本文件定义了一个测试标准，通过观察衰减变化来确定电缆承受温度循环影响的能力。 有关所有类型测试方法的参考指南及一般要求和定义，请参阅IEC 60794-1-2。 [外文原描述]： IEC 60794-1-201: 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 the ability of a cable to withstand the effects of temperature cycling by observing changes in attenuation. See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements and definitions. This document partially 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) all references to the temperature sensing device have been removed and replaced with a note "for further study"; b) the conditioning procedure has been separated into Procedure 1 and Procedure 2 to avoid confusion; c) the ambient temperature test condition has been defined as per IEC 60794-1-2; d) the minimum soak time has been decreased for sample mass >16 kg in Table 1.
