EN 60079-26:2004

Electrical apparatus for explosive gas atmospheres - Part 26: Construction, test and marking of Group II Category 1 G electrical apparatus

Specifies the particular requirements for construction, test and marking for electrical apparatus of Group II intended for use in Zone 0. This electrical apparatus, within the operational parameters specified by the manufacturer, ensures a very high level of protection that includes rare faults related to the apparatus or two faults occurring independently of each other. It is intended for use in Zone 0 hazardous areas, in which explosive gas atmospheres caused by mixtures of air and gases, vapours or mists under normal atmospheric conditions are present continuously, for long periods or frequently.

Elektrische Betriebsmittel für gasexplosionsgefährdete Bereiche - Teil 26: Konstruktion, Prüfung und Kennzeichnung elektrischer Betriebsmittel der Gruppe II Kategorie 1 G

Matériel électrique pour atmosphères explosives gazeuses - Partie 26: Construction, essais et marquage des matériels électriques de Groupe II Catégorie 1 G

Spécifie les prescriptions particulières pour la construction, les essais et le marquage des matériels électriques du Groupe II destinés à être utilisés en Zone 0. Lorsqu'ils sont utilisés dans le domaine opérationnel spécifié par le constructeur, de tels matériels assurent un très haut niveau de protection même dans les cas rares de défaut dû au matériel, ou de deux défauts indépendants l'un de l'autre. Ils sont destinés à une utilisation dans des emplacements dangereux de Zone 0, dans lesquels des atmosphères explosives gazeuses formées d'un mélange d'air et de gaz, de vapeurs ou de brouillards dans des conditions atmosphériques normales sont présentes continuellement, durablement ou fréquemment.

Foreword
The text of document 31/483/FDIS, future edition 1 of IEC 60079-26, 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 60079-26 on 2004-04-01.
Directive 94/9/EC requires equipment classification according to categories. Therefore, in all clauses
where the text of IEC 60079-26 uses the term "Zone 0 Equipment", or equivalent, this shall be
interpreted as referring to equipment of Category 1 G.
To this end, a draft amendment, prepared by the Technical Committee CENELEC TC 31, Electrical
apparatus for explosive atmospheres - General requirements, was submitted to the formal vote and was
approved by CENELEC for inclusion into EN 60079-26 on 2004-09-22.
This European Standard supersedes EN 50284:1999.
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) 2005-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-04-01
