EN 60079-26:2007

Explosive atmospheres - Part 26: Equipment with equipment protection level (EPL) Ga

This part of IEC 60079 specifies the particular requirements for construction, test and marking for electrical equipment that provides equipment protection level (EPL) Ga. This electrical equipment, within the operational parameters specified by the manufacturer, ensures a very high level of protection that includes rare faults related to the equipment or two faults occurring independently of each other. The contents of the corrigendum of March 2009 have been included in this copy.

Explosionsfähige Atmosphäre - Teil 26: Betriebsmittel mit Geräteschutzniveau (EPL) Ga

Atmosphères explosives - Partie 26: Matériel d'un niveau de protection du matériel (EPL) Ga

La présente partie de la CEI 60079 spécifie les exigences particulières pour la construction, les essais et le marquage des matériels électriques qui procurent un niveau de protection du matériel (EPL) Ga. Ce matériel électrique assure, dans les limites des paramètres de fonctionnement spécifiés par le constructeur, un très haut niveau de protection prenant en compte le cas des pannes rares liées au matériel, ou d'apparition simultanée de deux pannes indépendantes l'une de l'autre. Le contenu du corrigendum de mars 2009 a été pris en considération dans cet exemplaire.

Foreword
The text of document 31/630/FDIS, future edition 2 of IEC 60079-26, prepared by IEC TC 31, Equipment
for explosive atmospheres, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60079-26 on 2006-10-01.
This European Standard supersedes EN 60079-26:2004.
The significant changes with respect to EN 60079-26:2004 are:
– changes concerning the accessible chargeable surfaces of the equipment;
– requirements of a partition wall combined with an air-gap with natural ventilation;
– introduction of equipment protection levels (EPL) and substitution of the references to zones (see
explanation in Annex A);
– change of heading from “Mechanical connection” to “Process connection” together with a clarification
of requirement for any release from Zone 0 of explosive gas atmospheres.
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) 2007-10-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-10-01
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.
This European Standard covers Category 1G and combined Category 1/2G electrical equipment.
NOTE Other EC Directives may be applicable
To be in line with the requirements given in Directive 94/9/EC the text given in the body of the standard
should be interpreted as given in the following table.
