标准摘要
[中文适用范围]： IEC 60794-1-207:2025描述了用于建立光纤电缆环境性能要求的测试方法，具体为光纤电缆在暴露于核辐射时的性能退化情况。本文件适用于用于电信设备及采用类似技术的设备的光纤电缆，也适用于同时包含光纤和导电元件的电缆。方法F7A评估光纤电缆在环境背景辐射下的性能退化；方法F7B评估光纤电缆在恶劣核环境下的性能退化。注：本文档中，“光纤电缆”一词也可包括光纤单元、微孔光纤单元等。本版取消并替换了IEC 60794-1-22第二版中发布于2017年的方法F7。本版为技术修订版。与前一版相比，本版包含以下重大技术变更：a) 增加了样品、设备、程序、要求和方法的具体内容、详细信息及报告要求。 [外文原描述]： IEC 60794-1-207:2025 describes test procedures to be used in establishing uniform requirements for optical fibre cables for the environmental property: performance degradation when exposed to nuclear radiation. 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. Method F7A evaluates performance degradation of optical fibre cable in environmental background radiation; Method F7B evaluates performance degradation of optical fibre cable in adverse nuclear environments. NOTE Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. This first edition cancels and replaces the method F7 of the second edition of IEC 60794-1-22 published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) detailed content of sample, apparatus, procedure, requirements and details of the method to be specified and reported are added.
