IEC 60079-0:20 17 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 60079-0:20 17规定了用于爆炸性环境的防爆设备和防爆组件的构造、测试和标记的一般要求。可以假定Ex设备可以运行的标准大气条件（与大气的爆炸特性有关）是: -温度-20℃至+60℃； -压力80kPa(0.8巴)至110kPa(1.1巴)；和 -具有正常氧含量的空气，通常为21%v/v。 IEC 60079的这一部分和补充本标准的其他标准规定了在标准温度范围之外运行的Ex设备的附加测试要求，但对于在标准大气压范围和标准氧含量之外运行的Ex设备，可能需要进一步的附加考虑和附加测试。此类附加测试可能与依赖于火焰熄灭的保护类型特别相关，例如“隔爆外壳“d”（IEC 60079-1）或能量限制“本质安全“i”（IEC 60079-11）。？第七版取消并取代了2011年出版的第六版。此版本构成技术修订。？有关第7版之间技术变更的完整列表，请参阅文档的前言。0和文档的前一版本。 关键词:用于爆炸性环境的防爆设备和防爆部件

IEC 60079-0:2017 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 60079-0:2017 specifies the general requirements for construction, testing and marking of Ex Equipment and Ex Components intended for use in explosive atmospheres. The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it may be assumed that Ex Equipment can be operated are:
-temperature –20 °C to +60 °C;
-pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and
-air with normal oxygen content, typically 21 % v/v.
This part of IEC 60079 and other standards supplementing this standard specify additional test requirements for Ex Equipment operating outside the standard temperature range, but further additional consideration and additional testing may be required for Ex Equipment operating outside the standard atmospheric pressure range and standard oxygen content. Such additional testing may be particularly relevant with respect to Types of Protection that depend on quenching of a flame such as ‘flameproof enclosures “d”’ (IEC 60079-1) or limitation of energy, ‘intrinsic safety “i”’ (IEC 60079-11).？ This seventh edition cancels and replaces the sixth edition, published in 2011. This edition constitutes a technical revision.？ Refer to the Forward of the document for a complete listing of the technical changes between edition 7.0 and the previous edition of the document.
