  Description:

Explosive atmospheres - Part 11: Equipment protection by intrinsic safety 'i'

  Purpose

EN 60079-11 specifies the construction and testing of intrinsically safe apparatus used in an explosive atmosphere. It also covers associated apparatus, which is intended for connection to intrinsically safe circuits which enter such atmospheres. This type of protection applies to electrical equipment in which the electrical circuits themselves are incapable of causing an explosion in the surrounding explosive atmospheres. EN 60079-11 is also applicable to electrical equipment or parts of electrical equipment located outside the explosive atmosphere. The equipment can be protected by another type of protection, where the intrinsic safety of the electrical circuits in the explosive atmosphere may depend upon the design and construction. The electrical circuits exposed to the explosive atmosphere are evaluated for use in such an atmosphere by applying EN 60079-11. EN 60079-11 is for electrical equipment only, which means the term “equipment” used in the standard always means “electrical equipment”. The international standard has been approved in Europe as EN 60079-11:2012 without any changes.
