标准范围

IEC 60794-1-307:2025描述了用于建立管材机械性能扭结统一要求的测试程序。本文件适用于与采用类似技术的电信设备和装置一起使用的光纤电缆，以及具有光纤和电导体的组合的电缆。在整个文件中，措辞“光缆”还可以包括光纤单元、微导管光纤单元等。这第一版部分取消并取代了IEC 60794的第二版？2019年出版的1-23。本版构成技术修订版。本版本包括以下与IEC 60794相关的重大技术变化？1？23:2019:a)将现有测试方法G7重新编号为G7A；b)对于方法G7A，在表1中添加测试参数L和计算的环直径D；c)为在安装设备内布线的管道增加了新的测试程序，并将其编号为G7B。

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.
