Full Description

CSA Preface

This is the second edition of CAN/CSA-C22.2 No. 60079-6, Explosive atmospheres - Part 6: Equipment protection by liquid immersion "o", which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60079-6 (fourth edition, 2015-02). It supersedes the previous edition published in 2011 as CAN/CSA-C22.2 No. 60079-6, Explosive atmospheres - Part 6: Equipment protection by oil immersion "o" (adopted IEC 60079-6:2007). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code.

For brevity, this Standard will be referred to as "CAN/CSA-C22.2 No. 60079-6" throughout.

This Standard is intended to be used in conjunction with CAN/CSA-C22.2 No. 60079-0, Explosive atmospheres - Part 0: Equipment - General requirements.

Changes to this edition include the following:

a) The requirements for oil immersion "o" have been redefined into liquid immersion, levels of protection "ob" and "oc" as recommended by the responses to 31/715/DC.

b) The ability to protect sparking contacts has been added to both "ob" and "oc".

c) Additional requirements have been introduced for the protective liquid.

Scope

This part of IEC 60079 specifies the requirements for the design, construction, testing and marking of Ex Equipment and Ex Components with type of protection liquid immersion "o" intended for use in explosive gas atmospheres.

Ex Equipment and Ex Components of type of protection liquid immersion "o" are either:

- Level of Protection "ob" (EPL "Mb" or "Gb")

- Level of Protection "oc" (EPL "Gc")

For Level of Protection "ob", this standard applies where the rated voltage does not exceed 11 kV r.m.s. a.c. or d.c.

For Level of Protection "oc", this standard applies where the rated voltage does not exceed 15 kV r.m.s. a.c. or d.c.

NOTE Requirements for higher voltages are under consideration.

This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence.

Préface CSA

Ce document constitue la deuxième édition de la CAN/CSA-C22.2 nº 60079-6, Atmosphères explosives - Partie 6 : Protection du matériel par immersion dans le liquide «o». Il s'agit de l'adoption, avec exigences propres au Canada, de la norme IEC (Commission Électrotechnique Internationale) 60079-6 (quatrième édition, 2015-02) qui porte le même titre. Il remplace l'édition antérieure publiée en 2011 qui portait la désignation CAN/CSA-C22.2 nº 60079-6, Atmosphères explosives - Partie 6 : Protection du matériel par immersion dans l'huile «o» (norme IEC 60079-6:2007 adoptée). Il fait partie d'une série de normes publiées par le Groupe CSA qui constituent le Code canadien de l'électricité, Deuxième partie.

Par souci de brièveté, tout au long de ce document, il sera appelé «CAN/CSA-C22.2 nº 60079-6».

Cette norme doit être utilisée avec la CAN/CSA-C22.2 nº 60079-0, Atmosphères explosives - Partie 0 : Matériel - Exigences générales.

Voici les principaux changements apportés à cette édition :

a) Les exigences relatives à l'immersion dans l'huile «o» traitent désormais de l'immersion dans un liquide, de niveaux de protection «ob» et «oc», selon les recommandations des réponses au document 31/715/DC.

b) La capacité à protéger les contacts à décharge disruptive a été ajoutée aux niveaux de protection «ob» et «oc».

c) Des exigences supplémentaires relatives au liquide de protection ont été introduites.

Domaine d'application

La présente partie de l'IEC 60079 spécifie les exigences de conception, de construction, d'essais et de marquage d'un matériel Ex et de composants Ex, de mode de protection immersion dans le liquide "o", destinés à être utilisés dans des atmosphères explosives gazeuses.

Un matériel Ex et des composants Ex de mode de protection immersion dans le liquide "o" peuvent être du:

- Niveau de Protection "ob" (EPL "Mb" ou "Gb"), ou

- Niveau de Protection "oc" (EPL "Gc")

Pour le Niveau de Protection "ob", la présente norme s'applique si la tension assignée est inférieure à 11 kV eff. c.a. ou c.c.

Pour le Niveau de Protection "oc", la présente norme s'applique si la tension assignée est inférieure à 15 kV eff. c.a. ou c.c.

NOTE Des exigences pour des tensions plus élevées sont à l'étude.

La présente norme complète et modifie les exigences générales de l'IEC 60079-0. Lorsqu'une exigence de la présente norme entre en contradiction avec une exigence de l'IEC 60079-0, l'exigence de la présente norme prévaut.
