新的！IEC 60079-2:20 14作为IEC标准+60079-2:20 14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 60079-2:20 14包含用于爆炸性气体环境或爆炸性粉尘环境的带“p”保护类型加压外壳的电气设备的构造和测试的具体要求。它还包括对含有有限释放的易燃物质的加压外壳的要求。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。本标准不包括以下要求:-加压外壳，其中安全壳系统可以释放氧含量大于正常的空气，或氧气与惰性气体的组合，其中氧气的比例大于21%； -加压室或分析仪室；参见IEC 60079-13； -在存在“爆炸物”或烟火的情况下使用的加压外壳； -在存在气体/蒸汽和可燃粉尘的混合混合物的情况下使用的加压外壳； -在存在自燃物质如炸药或含有自身氧化剂的推进剂的情况下使用的加压外壳； -具有内部可燃粉尘释放源的加压外壳。 这第六版取消并取代了2007年出版的第五版。本第六版取消并取代第一版IEC 61241-4发表于2001年。这第六版构成技术修订。IEC 60079-2，第6.0版（2014）和IEC 60079-2，第5.0版（2007）之间变更的意义列于文件的前言中。 关键词:带加压外壳的电气设备，保护类型“p”，爆炸性气体环境，爆炸性粉尘环境

NEW! IEC 60079-2:2014 is available as IEC Standards+ 60079-2:2014 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60079-2:2014 contains the specific requirements for the construction and testing of electrical equipment with pressurized enclosures, of type of protection "p", intended for use in explosi ve gas atmospheres or explosive dust atmospheres. It also includes the requirements for pressurized enclosures containing a limited release of a flammable substance. 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 requirements of this standard take precedence. This standard does not include the requirements for:
- pressurized enclosures where the containment system may release air with an oxygen content greater than normal, or oxygen in combination with inert gas where the oxygen is in a proportion greater than 21 %;
- pressurized rooms or analyser houses; see IEC 60079-13;
- pressurized enclosures used where "explosives" or pyrotechnics are present;
- pressurized enclosures used where hybrid mixtures of gas/vapour and combustible dust are present;
- pressurized enclosures used where pyrophoric substances such as explosives or propellants containing their own oxidizers are present;
- pressurized enclosures with an internal source of release of combustible dust.
This sixth edition cancels and replaces the fifth edition published in 2007. This sixth edition cancels and replaces the first edition of IEC 61241-4 published in 2001. This sixth edition constitutes a technical revision. The significance of changes between IEC 60079-2, Edition 6.0, 2014 and IEC 60079-2, Edition 5.0, 2007 are as listed in the foreword of the document. Keywords: electrical equipment with pressurized enclosures, type of protection "p", explosive gas atmospheres, explosive dust atmospheres
