    • Preface/Scope
    Preface

    This is the first edition of CAN/CSA-C22.2 No. 60079-5, Explosive atmospheres - Part 5: Equipment protection by powder filling q, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60079-5 (third edition, 2007-03). It replaces the previous edition published in 2002 as CAN/CSA-E60079-5, Electrical apparatus for explosive gas atmospheres - Part 5: Powder filling q (adopted CEI/IEC 60079-5:1997). It is one in a series of Standards issued by CSA under Part II of the Canadian Electrical Code.

    This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

    Scope

    This part of IEC 60079 contains specific requirements for the construction, testing and marking of electrical equipment, parts of electrical equipment and Ex components in the type of protection powder filling q, intended for use in explosive gas atmospheres.

    NOTE 1 Electrical equipment and Ex components protected by powder filling q may contain electronic circuits, transformers, protection fuses, relays, intrinsically safe electrical apparatus, associated electrical apparatus, switches, etc.

    NOTE 2 Type of protection powder filling q provides equipment protection level (EPL) Gb. For further information, see Annex A.

    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 will take precedence.

    This Standard applies to electrical equipment, parts of electrical equipment and Ex components with:
    • a rated supply current less than or equal to 16 A;
    • a rated supply voltage less than or equal to 1 000 V;
    • a rated power consumption less than or equal to 1 000 W.

    Préface CSA

    Ce document constitue la première édition de la CAN/CSA-C22.2 nº 60079-5, Atmosphères explosives - Partie 5 : Protection du matériel par remplissage pulvérulent «q». Il s'agit de l'adoption, avec exigencies propres au Canada, de la norme CEI (Commission Électrotechnique Internationale) 60079-5 (troisième édition, 2007-03) qui porte le même titre. Cette norme remplace l'édition précédente publiée en 2002 qui portait la désignation CAN/CSA-E60079-5, Matériel électrique pour atmosphères explosives gazeuses - Partie 5 : Remplissage pulvérulent «q» (norme CEI/IEC 60079-5:1997 adoptée). Cette norme fait partie d'une série de normes publiées par CSA lesquelles constituent le Code canadien de l'électricité, Deuxième partie.

    Cette norme est jugée convenable à l'évaluation de la conformité selon le domaine d'application établi dans la norme.

    Domaine d'application

    La présente partie de la CEI 60079 contient les exigences spécifiques de construction, d'essais et de marquage du matériel électrique, des parties de matériel électrique et des composants Ex à remplissage pulvérulent, mode de protection «q», destinés àêtre utilizes dans des atmosphères explosives gazeuses.

    NOTE 1 Le matériel électrique à remplissage pulvérulent et les composants Ex peuvent contenir des circuits électroniques, des transformateurs, des fusibles de protection, des relais, des matériels électriques de sécurité intrinsèque, des matériels électriques associés, des interrupteurs, etc.

    NOTE 2 Le mode de protection par remplissage pulvérulent « q » apporte un niveau de protection du materiel (EPL pour equipement protection level) Gb. Pour plus d'informations, voir l'Annexe A.

    La présente norme complète et modifie les exigences générales de la CEI 60079-0. Lorsqu'une exigence de la présente norme diverge d'une exigence de la CEI 60079-0, l'exigence de cette norme prévaudra.

    La présente norme s'applique au matériel électrique, aux parties de matériel électrique et aux composants Ex dont:
    • le courant assigné est inférieur ou égal à 16 A;
    • la tension assignée est inférieure ou égale à 1 000 V;
    • la puissance assignée est inférieure ou égale à 1 000 W.
