标准摘要
[中文适用范围]： 本部分IEC 60079包含了对用于爆炸性气体环境中的电气设备、电气设备部件和Ex组件在粉末填充型保护“q”中的构造、测试和标记的特定要求。 注1：通过粉末填充“q”保护的电气设备和Ex组件可以包含电子电路、变压器、保护熔断器、继电器、本质安全电气设备、关联电气设备、开关等。 注2：粉末填充型保护“q”提供设备保护等级（EPL）Gb或Mb。 本标准补充并修改了IEC 60079-0的一般要求。当本标准的要求与IEC 60079-0的要求冲突时，以本标准的要求为准。 本标准适用于具有以下特性的电气设备、电气设备部件和Ex组件： - 额定电源电流小于或等于16A； - 额定电源电压小于或等于1000V； - 额定功耗小于或等于1000W。 [外文原描述]： IEC 60079-5:2015+AMD1:2022 CSV 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"
