标准摘要
[中文适用范围]： IEC 60794-1-307:2025描述了用于确立光缆管抗弯折机械性能统一要求的测试程序。本文件适用于用于电信设备和采用类似技术的装置的光缆，以及同时包含光纤与电导体的复合光缆。全文中，“光缆”一词亦涵盖光纤单元、微孔光纤单元等。本第一版部分替代并废止2019年发布的IEC 60794-1-23第二版，属技术修订版。相对于IEC 60794-1-23:2019，本版本包含以下重要技术变更：a）将原测试方法G7重新编号为G7A；b）在方法G7A对应的表1中增加测试参数L及计算得到的环径D；c）新增针对安装装置内部布放管路的测试程序，编号为G7B。 [外文原描述]： IEC 60794-1-307:2025 describes test procedures used in establishing uniform requirements of tubes for the mechanical property kinking. 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 first edition partially cancels and replaces the second edition of IEC 60794‑1-23 published in 2019. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to IEC 60794‑1‑23:2019: a) renumbering of the existing test method G7 as G7A; b) addition of test parameter L and calculated loop diameter D in Table 1 for method G7A; c) addition of a new test procedure for tubes routed within installation devices and numbering it as G7B.
