BS EN 60079-0 Explosive atmospheres. Equipment. Updated

BS EN 60079-0 specifies the general requirements for construction, testing and marking of electrical equipment and Ex components intended for use in explosive atmospheres.

Publication Date: 30 September 2012 and Replaces BS EN 60079-0:2009

Unless modified by another standard, electrical equipment complying with BS EN 60079-0 is intended for use in hazardous areas in which explosive atmospheres exist under normal atmospheric conditions of:

• 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.

The application of electrical equipment in atmospheric conditions outside this range requires special consideration and may require additional assessment and testing.
