爆炸性环境 第14部分：电气装置设计、设备选择和安装 包括初始检查

[中文适用范围]： 本部分IEC 60079包含了对电气系统设计、选择、安装以及爆炸性环境中或与之相关的Ex设备的电气安装所需初始检查的具体要求，包括文档和人员能力的要求。这些要求是对非危险区域安装要求的补充。本文件适用于所有电气Ex设备，包括固定式、便携式、移动式和个人设备，以及永久性或临时性安装。本文件不适用于：易受沼气影响的矿井电气安装；固有爆炸性情况和爆炸物或自燃物质的粉尘；医疗用途的房间；易燃雾危险区域的电气安装；以及非电气Ex设备的安装（除非是IEC TS 60079-46中设备组装的一部分）。 [外文原描述]： IEC 60079:2024 contains the specific requirements for the design of electrical systems, selection, installation and the required initial inspection of electrical installations of Ex Equipment in, or associated with, explosive atmospheres including requirements for documentation and personnel competency. These requirements are in addition to the requirements for installations in non-hazardous areas. This document applies to all electrical Ex Equipment including fixed, transportable, portable and personal, and installations, permanent or temporary. This document does not apply to: • electrical installations in mines susceptible to firedamp; • inherently explosive situations and dust from explosives or pyrophoric substances (for example explosives manufacturing and processing); • rooms used for medical purposes; • electrical installations in areas where the hazard is due to flammable mist; and • installation of non-electrical Ex Equipment (unless being part of an equipment assembly according IEC TS 60079-46). No account is taken in this document of the toxic hazards that are associated with flammable gases, liquids and dusts in concentrations that are usually very much less than the lower flammable limit. In locations where personnel could be exposed to potentially toxic concentrations of flammable material, appropriate precautions are necessary. Such precautions are outside the scope of this document. This sixth edition cancels and replaces the fifth edition published in 2013. This edition constitutes a technical revision. Edition 6 is a major restructure and introduces a number of technical changes from the previous edition (2013), see Table 1 of the foreword for detailed information.
