IEC 60079的本部分规定了爆炸性气体环境中使用的防护等级为“e”的电气设备的设计、施工、测试和标记要求。本标准适用于电源电压额定值不超过11 kV r.m.s.a.c.或d.c.的电气设备。采取额外措施以确保设备在正常运行或规定的异常条件下不会产生电弧、火花或过高温度。这些具体要求是对IEC 60079-0中适用于增强安全“e”保护类型的一般要求的补充，除非特别排除在外。

This part of IEC 60079 specifies the requirements for the design, construction, testing and marking of electrical apparatus with type of protection increased safety "e" intended for use in explosive gas atmospheres. This standard applies to electrical apparatus with a rated value of supply voltage not exceeding 11 kV r.m.s. a.c. or d.c. Additional measures are applied to ensure that the apparatus does not produce arcs, sparks, or excessive temperatures in normal operation or under specified abnormal conditions.These specific requirements are additional to the general requirements in IEC 60079-0 that apply to type of protection increased safety "e" unless specifically excluded.
