IEC 60079:2024包含爆炸性环境中或与爆炸性环境相关的防爆设备的电气系统设计、选择、安装和电气装置所需初步检查的具体要求，包括文件和人员能力的要求。 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防爆设备，包括固定的、可运输的、便携式的和个人的，以及永久的或临时的装置。 本文件不适用于: ？易受火灾影响的矿井中的电气装置； ？固有爆炸性情况和来自爆炸物或自燃物质的粉尘（例如爆炸物制造和加工）； ？用于医疗目的的房间；？易燃薄雾造成危险区域的电气装置；和 ？非电气防爆设备的安装（除非是根据IEC TS 60079-46的设备组件的一部分）。 本文件未考虑与浓度通常远低于可燃下限的易燃气体、液体和粉尘相关的毒性危害。在人员可能暴露于潜在有毒浓度的易燃材料的场所，适当的预防措施是必要的。此类预防措施超出了本文档的范围。 本第六版取消并取代2013年出版的第五版。本版构成技术修订版。第6版是一次重大重组，引入了上一版（2013年）的多项技术变更，详细信息见前言表1。

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.
