Electrical apparatus for explosive gas atmospheres - Part 15: Construction, test and marking of type of protection "n" electrical apparatus
This part of EN 60079 specifies requirements for the construction, testing and marking for Group II electrical apparatus with type of protection, n intended for use in explosive gas atmospheres.This part is applicable to non-sparking electrical apparatus and also to electrical apparatus 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 EN 60079-0. This part supplements the general requirements in EN 60079-0.

Matériel électrique pour atmosphères explosives gazeuses - Partie 15: Construction, essais et marquage des matériels électriques du mode de protection "n"
La présente partie de la EN 60079 spécifie les exigences de construction, d'essai et de marquage du matériel électrique du Groupe II avec mode de protection n destiné à être utilisé en atmosphère explosive gazeuse. Cette partie s'applique au matériel électrique ne produisant pas d'étincelles, ainsi qu'au matériel électrique dont des parties ou circuits produisent des arcs ou des étincelles ou qui ont des surfaces chaudes qui, si elles n'étaient pas protégées selon l'une des manières mentionnées dans la présente norme, seraient susceptibles d'enflammer une atmosphère explosive gazeuse environnante. La présente norme décrit différentes méthodes permettant de résoudre ce problème et pouvant être combinées à d'autres méthodes décrites dans la EN 60079-0. Cette partie complète les exigences générales de la EN 60079-0.

Foreword
The text of document 31/558/FDIS, future edition 3 of IEC 60079-15, prepared by IEC TC 31,
Electrical apparatus for explosive atmospheres, was submitted to the IEC-CENELEC parallel vote and
was approved by CENELEC as EN 60079-15 on 2005-06-01.
This European Standard is to be read in conjunction with EN 60079-0.
This European Standard supersedes EN 60079-15:2003.
The significant technical changes with respect to EN 60079-15:2003 are as follows:
– linking the standard to EN 60079-0 and adding Table 1 to show the connections;
– references to third party testing stations removed;
– adding the definition of associated energy limiting apparatus [nL] and [Ex nL];
– definitions eliminated that also appear in EN 60079-0;
– elimination of n-pressurization, all pressurization requirements now covered by EN 60079-2;
– air gap spark test requirement added for motors over 100 kW;
– added risk assessment tables for motors over 1 kV and over 100 kW;
– requirements changed for motors operating with frequency converters;
– references to other IEC and European standards updated for luminaires;
– caplights and handlights addressed by reference to EN 60079-0;
– creepage and clearance requirements for low powered apparatus between 60 V a.c. up to
250 V a.c. added in Table 10;
– requirement for plugs and sockets to maintain the degree of protection expanded;
– cable clamping test eliminated;
– insertion and removal torque values for E40/E39 lamp caps adjusted downward;
– high-voltage impulse test for ballasts eliminated;
– changes made to test and acceptance criteria in luminaire starter and ignitor tests;
– ignition tests for large or high-voltage machines added;
– marking and documentation sections changed to reflect changes elsewhere in the standard;
– manufacturer’s responsibility section dropped and replaced with instructions section.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-05-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-06-01
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive 94/9/EC. See Annex ZZ.
Annexes ZA and ZZ have been added by CENELEC.
