IEC 60079-5:20 15+AMD1:2022包含用于爆炸性气体环境的电气设备、电气设备零件和防护粉末填充类型“q”的防爆组件的构造、测试和标记的具体要求。本标准对IEC 60079-0的一般要求进行了补充和修改。当本标准的要求与IEC 60079-0的要求相冲突时，以本标准的要求为准。本标准适用于具有以下条件的电气设备、电气设备零件和防爆元件: -小于或等于16A的额定电源电流； -小于或等于1000V的额定电源电压； -额定功耗小于或等于1000W。第四版取消并取代了2007年出版的第三版，构成了技术修订。有关4.0版和上一版文档之间技术变更的完整列表，请参阅文档前言。关键词:电气设备和防爆元件在类型的保护粉末填充“q”

IEC 60079-5:2015+AMD1:2022 contains specific requirements for the construction, testing and marking of electrical equipment, parts of electrical equipment and Ex components in the type of protection powder filling "q", intended for use in explosive gas atmospheres. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. This standard applies to electrical equipment, parts of electrical equipment and Ex components with:
- a rated supply current less than or equal to 16 A;
- a rated supply voltage less than or equal to 1 000 V;
- a rated power consumption less than or equal to 1 000 W. This fourth edition cancels and replaces the third edition, published in 2007, and constitutes a technical revision. Refer to the Foreword of the document for a complete listing of the technical changes between edition 4.0 and previous edition of the document. Keywords: electrical equipment and Ex components in the type of protection powder filling "q"
