BS EN 60079-2:2014

Explosive atmospheres. Equipment protection by pressurized enclosure "p"

Status : Work in hand, Current   Published : January 2015



What is this standard about?

This is Part 2 of the European standard on explosive atmospheres. It details how to construct and test electrical equipment with pressurized enclosures, specifically of type “p”.

Who is this standard for?

  • Manufacturers, designers and specifiers of electrical equipment with pressurized enclosures for use in explosive atmospheres
  • Those who test and maintain such equipment
  • Health and safety bodies
  • Regulatory bodies

Why should you use this standard?

It contains specific requirements for the design, construction, marking and testing of electrical equipment with pressurized enclosures of type of protection “p”, intended for use in explosive gas atmospheres or explosive dust atmospheres.

It also includes requirements for pressurized enclosures containing a limited release of a flammable substance.

This standard supplements and modifies the general requirements of BS EN 60079-0. Where a requirement of this standard conflicts with a requirement of BS EN 60079-0, the requirements of this standard take precedence.

NOTE: 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 BS EN 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

What’s changed since the last update?

This standard constitutes an extensive technical revision which supersedes BS EN 60079-2:2007 and BS EN 61241-4:2006 which are withdrawn. A large number of minor editorial changes were made along with twelve major technical changes that are detailed in informative Annex ZY.
