标准摘要
[中文适用范围]： IEC 60079-25:2020+AMD1:2025 CSV 包含对本质安全系统（保护类型“i”）的设计、构造和评估的具体要求，适用于需要使用 Group I、II 或 III 类 Ex 设备的场所，可整体或部分使用。本文件补充并修改了 IEC 60079-0 的一般要求以及本质安全标准 IEC 60079-11。当本标准的要求与 IEC 60079-0 或 IEC 60079-11 的要求发生冲突时，以本标准的要求为准。按照本标准设计的 Group II 或 Group III 系统的安装要求在 IEC 60079-14 中规定。本版为第三版，取消并替代了 2010 年发布的第二版，构成技术修订。2020 年 10 月发布的勘误 1 和 2022 年 11 月发布的勘误 2 的内容已包含在本文件中。 [外文原描述]： IEC 60079-25:2020+AMD1:2025 CSV contains the specific requirements for design, construction and assessment of intrinsically safe systems, Type of Protection “i”, intended for use, as a whole or in part, in locations in which the use of Group I, II or III Ex Equipment is required. This document supplements and modifies the general requirements of IEC 60079-0 and the intrinsic safety standard IEC 60079-11. Where a requirement of this standard conflicts with a requirement of IEC 60079-0 or IEC 60079-11, the requirement of this standard takes precedence. The installation requirements of Group II or Group III systems designed in accordance with this standard are specified in IEC 60079-14. This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The contents of the corrigendum 1 of October 2020 and corrigendum 2 of November 2022 have been included in this copy.
