Defines 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.

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. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Prface CSA Ce document constitue la deuxime dition de la CAN/CSA-C22.2 n 60079-6, Atmosphres explosives - Partie 6 : Protection du matriel par immersion dans le liquide o. Il s\'agit de l\'adoption, avec exigences propres au Canada, de la norme IEC (Commission lectrotechnique Internationale) 60079-6 (quatrime dition, 2015-02) qui porte le mme titre. Il remplace l\'dition antrieure publie en 2011 qui portait la dsignation CAN/CSA-C22.2 n 60079-6, Atmosphres explosives - Partie 6 : Protection du matriel par immersion dans l\'huile o (norme IEC 60079-6:2007 adopte). Il fait partie d\'une srie de normes publies par le Groupe CSA qui constituent le Code canadien de l\'lectricit, Deuxime partie. Par souci de brivet, tout au long de ce document, il sera appel CAN/CSA-C22.2 n 60079-6. Cette norme doit tre utilise avec la CAN/CSA-C22.2 n 60079-0, Atmosphres explosives - Partie 0 : Matriel - Exigences gnrales. Voici les principaux changements apports cette dition: a) Les exigences relatives l\'immersion dans l\'huile o traitent dsormais de l\'immersion dans un liquide, de niveaux de protection ob et oc, selon les recommandations des rponses au document 31/715/DC. b) La capacit protger les contacts dcharge disruptive a t ajoute aux niveaux de protection ob et oc. c) Des exigences supplmentaires relatives au liquide de protection ont t introduites. Domaine d\'application La prsente partie de l\'IEC 60079 spcifie les exigences de conception, de construction, d\'essais et de marquage d\'un matriel Ex et de composants Ex, de mode de protection immersion dans le liquide \"o\", destins tre utiliss dans des atmosphres explosives gazeuses. Un matriel Ex et des composants Ex de mode de protection immersion dans le liquide \"o\" peuvent tre du: Niveau de Protection \"ob\" (EPL \"Mb\" ou \"Gb\"), ou Niveau de Protection \"oc\" (EPL \"Gc\") Pour le Niveau de Protection \"ob\", la prsente norme s\'applique si la tension assigne est infrieure 11 kV eff. c.a. ou c.c. Pour le Niveau de Protection \"oc\", la prsente norme s\'applique si la tension assigne est infrieure 15 kV eff. c.a. ou c.c. NOTE Des exigences pour des tensions plus leves sont l\'tude. La prsente norme complte et modifie les exigences gnrales de l\'IEC 60079-0. Lorsqu\'une exigence de la prsente norme entre en contradiction avec une exigence de l\'IEC 60079-0, l\'exigence de la prsente norme prvaut.
