    Product Details

    • Preface/Scope
    Scope

    This report specifies requirements for the construction, assessment and testing of electrical apparatus with type of protection n which, when operating normally within its rated duty, is unlikely to be capable of igniting a surrounding explosive gas atmosphere.

    This report specifies the features of apparatus which shall be assessed to achieve a satisfactory level of safety for electrical apparatus for use in Zone 2.

    This report applies only to Group II electrical apparatus intended for use in locations with explosive gas atmospheres other than in mines subject to firedamp.

    The requirements of IEC Publication 79-0 do not apply to electrical apparatus with type of protection n.

    Notes:
    (1) This report does not prohibit the use of electrical apparatus complying with the requirements of a recognized standard for industrial electrical apparatus which does not in normal service produce arcs or sparks or ignition-capable hot surfaces. (See IEC Publication 79-14.)
    (2) This report is worded in the mandatory form because it was intended to be a Standard. It is up to each National Committee, when drafting a similar document based on this report, to decide which form of wording to use in their national standard or report. 

    Domaine d'application

    Le présent rapport spécifie les règles de construction, d'évaluation et d'épreuves du matériel électrique avec mode de protection «n» qui, lorsqu'il fonctionne
    à son service a ssigné, n'est pas susceptible d'enflammer une atmosphère explosive gazeuse environnante.

    Le présent rapport spécifie les caractéristiques d'un matériel qui doit être considéré comme atteignant un niveau de sécurité satisfaisant pour être utilisé en zone 

    Le présent rapport s'applique seulement au matériel électrique du Groupe II destiné à être utilisé dans des lieux en atmosphère explosive gazeuse autres que les mines grisouteuses.

    Les règles de la Publication 79-0 de la CEI ne s'appliquent pas au matériel électrique avec mode de protection «n».

    Notes :
    (1) Le présent rapport n'interdit pas l'utilisation d'un matériel électrique conforme aux prescriptions d'une norme reconnue p our du matériel électrique industriel qui, en service normal, n'engendre ni arcs, ni étincelles, ni surfaces chaudes susceptibles de provoquer une inflammation. (Voir la Publication 79-14 de la CEI.)
    (2) Le présent rapport est rédigé sous forme obligatoire parce qu'il était prévu d'en faire une norme. Il appartient à chaque Comité national, lors de la rédaction d'un document similaire basé sur le présent rapport, de décider de la forme du texte à ado pter dans sa norme ou son rapport national.
