IEC 60794-1-309:2023描述了用于建立光缆元件、填充化合物或溢流化合物环境特性（渗出和蒸发）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。 笔记？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。第一版IEC 60794-1-309取消并取代了2019年发布的第二版IEC 60794-1-23的方法G9。与上一版相比，此版本包括以下重大技术变更: a)IEC 60794-1-23:20 19中包含的光缆元件测试方法现在将在IEC 60794-1-3xx系列中单独编号。每个测试方法现在被认为是一个单独的文件，而不是多测试方法概要的一部分。IEC 60794-1-2中给出了完整的交叉引用细节； b)扩大了范围，使得测试方法也适用于驱油化合物； c)测试装置的盖子被取消。

IEC 60794-1-309:2023 describes the test procedures to be used in establishing uniform requirements for optical fibre cable elements, filling compounds or flooding compounds, for the environmental property-bleeding and evaporation. 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.
NOTE？Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. This first edition of IEC 60794-1-309 cancels and replaces method G9 of the second edition of IEC 60794-1-23 published in 2019. This edition includes the following significant technical changes with respect to the previous edition:
a) the optical cable element test methods contained in IEC 60794-1-23:2019 will now be individually numbered in the IEC 60794-1-3xx series. Each test method is now considered to be an individual document rather than part of a multi-test method compendium. Full cross-reference details are given in IEC 60794-1-2;
b) the scope is broadened so that the test method is also applicable for flooding compounds;
c) the cover of the test set-up is cancelled.
