DIN EN 60079-15:2011-02

This part of IEC 60079 specifies requirements for the construction, testing and marking for Group II electrical equipment with type of protection "n" intended for use in explosive gas atmospheres. This standard applies to electrical equipment where the rated voltage does not exceed 15 kV r.m.s. a.c. or d.c. This part of IEC 60079 is applicable to non-sparking electrical apparatus and also to apparatus with parts or circuits producing arcs or sparks or having hot surfaces which, if not protected in accordance with one of the methods specified in this standard, could be capable of igniting a surrounding explosive atmosphere. This standard describes several different methods which can be used to achieve this and which can be combined with other methods described in IEC 60079-0. The responsible Committee is K 241 "Schlagwetter- und explosionsgeschützte elektrische Betriebsmittel" ("Electrical apparatus for potentially explosive atmospheres") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
