    Product Details

    • Scope
    1. Scope
     
    1.1 This report gives guidance on the design, selection and erection of electrical installations in areas where there may be explosive gas atmospheres.
     
    Note: Although most of this report is worded in the mandatory form, it offers guidance on installation for which the non- mandatory form of wording is more appropriate. It is up to each National Committee drafting installation rules based on this report to decide which form of wording to use in their national standard or report.
     
    1.2 This report is applicable to all permanent electrical installations within the scope of IEC Publication 364-1: Electrical Installations of Buildings, Part 1: Scope, Object and Definitions. However, this report may be applied, where appropriate, to electrical installations at higher voltages than the upper limit of IEC Publication 364-1, namely 1000 V a.c. Wherever possible the recommendations of this report should also be applied to electrical installations which may be regarded as temporary, such as experimental, prototype or pilot industrial installations.
     
    1.3 This report is not applicable to:
     
    (a) electrical installations excluded by the scope of IEC Publication 364-1;
    (b) electrical installations in mines susceptible to firedamp;
     
    Note: It may apply to electrical installations in mines where explosive atmospheres other than firedamp may be formed and to electrical installations in the surface installation of mines.
     
    (c) electrical installations in areas where the hazard is due to ignitable dusts, or fibres, or from explosives. /
     

    1. Domaine d'application
     
    1.1 Le présent rapport constitue un guide pour la conception, le choix et la réalisation des installations électriques dans les emplacements où il peut y avoir des atmosphères explosives gazeuses.
     
    Note. Bien que la plus grande partie du présent rapport soit rédigée sous forme obligatoire, il s'agit en fait d'un guide d'installation pour lequel une forme non obligatoire aurait été plus appropriée. Il appartient à chaque Comité national qui établit des règles d'installation fondées sur le présent rapport de décider de la forme du texte à adopter dans sa norme ou son rapport national.
     
    1.2 Le présent rapport est applicable à toutes les installations électriques permanentes qui font partie du domaine d'application de la Publication 364-1 de la CEI: Installations électriques des bâtiments, Première partie: Domaine d'application, objet et définitions. Cependant, le présent rapport peut être appliqué, s'il y a lieu, aux installations électriques de tension plus élevée que la limite supérieure indiquée dans la Publication 364-1 de la CEI, c'est-à-dire 1000 V en courant alternatif. Partout où cela est possible, les recommandations du présent rapport devront aussi être appliquées aux installations électriques qui peuvent être considérées comme temporaires, telles que les installations expérimentales, les installations prototypes ou les installations industrielles pilotes.
     
    1.3 Le présent rapport n'est pas applicable:
     
    (a) aux installations électriques exclues du domaine d'application de la Publication 364-1 de la CEI;
    (b) aux installations électriques dans les mines grisouteuses;
     
    Note. Il peut s'appliquer aux installations électriques dans les mines dans lesquelles des atmosphères explosives autres que grisouteuses peuvent se former et aux installations électriques à la surface de mines.

     (c) aux installations électriques dans les emplacements où le danger provient de poussière ou de fibres inflammables ou bien de substances explosives.
