标准摘要
[中文适用范围]： IEC 60794-208:2025 规定了用于确立充气式防护的无填充光缆抗气压环境性能统一要求的试验程序。本文件适用于采用类似技术的光缆，用于电信设备及装置，也适用于同时包含光纤和电气导体的复合光缆。注：全文中“光缆”一词亦可涵盖光纤单元、微管光纤单元等。本 IEC 60794-1-208 版为第一版，废止并取代 2017 年发布的 IEC 60794-1-22 第二版中的 F8 方法。本版属技术修订版，与前一版相比，主要技术变更如下：a) 修改了抗气压计算公式的形式，以便于在非 62 kPa 试验压力下计算；b) 增加了需报告的细节内容。 [外文原描述]： IEC 60794-208:2025 describes test procedures to be used in establishing uniform requirements for optical fibre cables for the pneumatic resistance environmental property, for unfilled cables which are protected by gas pressurization. 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 60794‑1‑208 cancels and replaces method F8 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) the form of the formula for pneumatic resistance is modified for ease of calculation with test pressures other than 62 kPa; b) details to be reported are added. The content of the corrigendum 1 (2025-12) has been included in this copy.
