|Publication Date:||15 February 2013|
This part of IEC 60079 specifies requirements for the construction, testing and marking for Group II electrical equipment with type of protection, ²n² 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.
1DV.1 DR Modification of Clause 1, first paragraph as follows:
1DV.1.1 Replace "part of IEC 60079" with "standard".
This part of IEC 60079 is applicable to non-sparking electrical equipment and also to electrical equipment with parts or circuits producing arcs or sparks or having hot surfaces which, if not protected in one of the ways specified in this standard, could be capable of igniting a surrounding explosive gas atmosphere. This standard describes several different methods by which this can be achieved which may be combined with other methods described in IEC 60079-0.
1DV.2 DR Modification of Clause 1, second paragraph as follows:
1DV.2.1 Replace "part of IEC 60079" with "standard".
