新的！IEC 60079-15:20 17作为IEC 60079-15:20 17 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60079-15:20 17规定了保护类型为“n”的II类电气设备的构造、测试和标记要求，包括:用于爆炸性气体环境的密封装置“nC”、气密密封装置“nC”、非易燃部件“nC”和限制性呼吸外壳“nR”。IEC 60079的这一部分适用于额定输入电压不超过15 kV r.m.s.的电气设备。交流或DC，包括Ex产品的内部工作电压超过15kV的地方，例如用于HID灯具的启动器。IEC 60079的这一部分补充和修改了IEC 60079的一般要求-0，表1（条款1）中所示除外。如果IEC 60079本部分的要求与IEC 60079-0的要求相冲突，则以IEC 60079本部分的要求为准。第五版取消并取代了2010年出版的第四版，构成了技术修订。有关5.0版与文档上一版之间技术变更的完整列表，请参阅文档的前言。 关键词:保护类型“n”的II类电气设备

NEW!IEC 60079-15:2017 is available as IEC 60079-15:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60079-15:2017 specifies requirements for the construction, testing and marking for Group II electrical equipment with type of protection “n” which includes; sealed devices “nC”, hermetically sealed devices “nC”, non-incendive components “nC” and restricted breathing enclosures “nR” intended for use in explosive gas atmospheres. This part of IEC 60079 applies to electrical equipment where the rated input voltage does not exceed 15 kV r.m.s. AC or DC including where the internal working voltages of the Ex product exceeds 15 kV, for example starters for HID luminaires. This part of IEC 60079 supplements and modifies the general requirements of IEC 60079-0, except as indicated in Table 1 (Clause 1). Where a requirement of this part of IEC 60079 conflicts with a requirement of IEC 60079-0, the requirement of this part of IEC 60079 takes precedence. This fifth edition cancels and replaces the fourth edition, published in 2010, and constitutes a technical revision. Refer to the Forward of the document for a complete listing of the technical changes between edition 5.0 and the previous edition of the document.
