IEC 60794-301:2023描述了用于建立光纤电缆元件机械性能弯曲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。本文件部分取消并取代IEC 60794-1-23:20 19。本版本包括以下与IEC 60794-1-23:20 19相关的重大技术变更: a)关于设备的参考测试方法IEC 60793-1-40被删除； b)添加的关于详细说明书中规定的温度的信息； c)添加了包含要报告的详细信息的新子条款。

IEC 60794-301:2023 describes test procedures to be used in establishing uniform requirements of optical fibre cable elements for the mechanical property – bending. 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 document partially cancels and replaces IEC 60794-1-23:2019. This edition includes the following significant technical changes with respect to IEC 60794-1-23:2019:
a) reference test method IEC 60793-1-40 removed regarding the apparatus;
b) information added regarding the temperature to be specified in the detail specification;
c) new subclause added containing the details to be reported.
