IEC 60079-10-1:20 08涉及可能出现易燃气体或蒸汽或雾危险的区域的分类，然后可用作支持正确选择和安装危险区域使用的设备的基础。它旨在应用于由于在正常大气条件下与空气混合的易燃气体或蒸汽的存在而可能存在点火危险的地方，但它不适用于 a)易受火灾影响的地雷； b)爆炸物的加工和制造； c)由于存在可燃粉尘或纤维而可能产生危险的区域； d)超出异常概念的灾难性故障； e)用于医疗目的的ROMMO； f)住宅处所。 本第一版IEC 60079-10-1取消并取代第四版IEC 60079-10，2002年出版，构成技术修订。与上一版相比，重大技术变化如下: -引入附件D，该附件涉及高闪点液体在压力下释放产生的易燃烟雾的爆炸危险； -引入条款A.3（释放速率），该条款给出了释放速率的热力学方程以及用于估计流体和气体释放速率的许多示例。

IEC 60079-10-1:2008 is concerned with the classification of areas where flammable gas or vapour or mist hazards may arise and may then be used as a basis to support the proper selection and installation of equipment for use in a hazardous area. It is intended to be applied where there may be an ignition hazard due to the presence of flammable gas or vapour, mixed with air under normal atmospheric conditions, but it does not apply to
a) mines susceptible to firedamp;
b) the processing and manufacture of explosives;
c) areas where a hazard may arise due to the presence of combustible dusts or fibres;
d) catastrophic failures which are beyond the concept of abnormality;
e) rommos used for medial purposes;
f) domestic premises.
This first edition of IEC 60079-10-1 cancels and replaces the fourth edition of IEC 60079-10, published in 2002, and constitutes a technical revision. The significant technical changes with respect to the previous edition are:
- introduction of Annex D which deals with explosion hazard from flammable mists generated by the release under pressure of high flash point liquids;
- introduction of Clause A.3 (release rate) which gives thermodynamic equations for release rate with a number of examples for estimating release rate of fluids and gases.
