标准摘要
[中文适用范围]： IEC 60079 的这一部分规定了用于爆炸性气体环境的具有增强安全保护类型“e”的电气设备的设计、构造、测试和标记的要求。本标准适用于额定电压不超过11 kV rmsac或dc的电气设备，并采取附加措施以确保设备在正常运行或规定的异常条件下不产生电弧、火花或过高的温度。本标准补充和修改了IEC 60079-0的一般要求。当本标准的要求与 IEC 60079-0 的要求相冲突时，以本标准的要求为准。注：增强安全性“e”可提供设备保护级别 (EPL) Mb 或 Gb。欲了解更多信息，请参阅附件一。 [外文原描述]： 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 where the rated voltage does not exceed 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.
