标准摘要
[中文适用范围]： IEC 62561-2:2025 RLV 包含正式的IEC国际标准及其红线版本。红线版本仅提供英文版，便于您快速、直观地比较当前IEC标准与上一版之间的所有变更。IEC 62561-2:2025 规定了以下内容的要求和测试：– 组成接闪器和引下线系统的金属导体（不包括“自然”导体），以及– 组成接地系统的金属接地电极。本版为第三版，取代2018年发布的第二版。本版为技术修订版，与前一版相比，包括以下重大技术变更：a) 增加了本文档中提到的新类型导体的定义；b) 根据IEC 60068-2-52:2017 对盐雾处理进行了更新；c) 根据ISO 22479:2019 对潮湿硫化气氛处理进行了更新；d) 增加了新的规范性附录H，用于材料、配置和截面积测试；e) 增加了新的规范性附录I，用于以前测试的适用性；f) 引入了等电位接地网格。 [外文原描述]： IEC 62561-2:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62561-2:2025 specifies the requirements and tests for - metallic conductors (other than "natural" conductors) that form part of the air-termination and down-conductor systems, and - metallic earth electrodes that form part of the earth-termination system. This third edition cancels and replaces the second edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) definitions of new conductor types mentioned in this document have been added; b) the document has been updated in line with IEC 60068-2-52:2017 on salt mist treatment; c) the document has been updated in line with ISO 22479:2019 on humid sulphurous atmosphere treatment; d) a new normative Annex H for material, configuration and cross-sectional area test has been introduced; e) a new normative Annex I for applicability of previous tests has been introduced. f) equipotential earth grid has been introduced.
