这是爆炸性气体环境的国际标准。
英文介绍:
This part of IEC 60079 specifies the general requirements for construction, testing and marking of electrical 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 electrical 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 standard and other standards supplementing this standard specify additional test requirements for equipment operating outside the standard temperature range, but further additional consideration and additional testing may be required for equipment operating outside the standard atmospheric pressure range and standard oxygen content, particularly with respect to types of protection that depend on quenching of a flame such as ‘flameproof enclosure “d”’ (IEC 60079-1) or limitation of energy, ‘intrinsic safety “i”’ (IEC 60079-11).

IEC60079系列标准是防爆电气设备安全要求,这是个系列标准。不同产品不同使用环境,标准是不一样的。
