Electrical apparatus for explosive gas atmospheres - Part 7: Increased safety “e”
Executive summary
Requirements for the design, construction, testing and marking of electrical apparatus with type of protection increased safety "e" used in explosive gas atmospheres.
Abstract
This part of EN 60079 specifies the requirements for the design, construction, testing and marking of electrical apparatus with type of protection increased safety "e" intended for use in explosive gas atmospheres. This European Standard applies to electrical apparatus with a rated value of supply voltage not exceeding 11 kV r.m.s. a.c. or d.c. Additional measures are applied to ensure that the apparatus does not produce arcs, sparks, or excessive temperatures in normal operation or under specified abnormal conditions.
These specific requirements are additional to the general requirements in
EN 60079-0 that apply to type of protection increased safety "e" unless specifically excluded.
