Lorsque vous utilisez des produits adapt\u00e9s \u00e0 une atmosph\u00e8re ATEX, vous devez garder \u00e0 l’esprit qu’il existe 5 typologie :<\/p>\n

    \n
  • Composant : les composants Ex, tels que les bo\u00eetiers vides ou les bornes, qui ne disposent que d’un certificat de composant Ex, marqu\u00e9 du suffixe \u00ab U \u00bb, ne peuvent pas \u00eatre utilis\u00e9s dans une zone dangereuse. Un composant doit devenir un \u00e9quipement pour pouvoir \u00eatre install\u00e9 dans une zone class\u00e9e.<\/li>\n
  • \u00c9quipement : les \u00e9quipements Ex peuvent \u00eatre install\u00e9s dans une zone class\u00e9e, mais ils doivent \u00eatre install\u00e9s et utilis\u00e9s dans le respect des caract\u00e9ristiques \u00e9lectriques en mati\u00e8re de puissance, tension, courant, fr\u00e9quence, service et autres caract\u00e9ristiques pour lesquelles une non-conformit\u00e9 pourrait entra\u00eener un risque d’inflammation.<\/li>\n
  • Appareils simples : il s’agit de composants passifs, par exemple des interrupteurs, des bo\u00eetes de jonction, des r\u00e9sistances et des dispositifs semi-conducteurs simples qui ne n\u00e9cessitent pas de marquage Ex. Toutefois, les appareils simples doivent \u00eatre clairement identifiables gr\u00e2ce \u00e0 un \u00e9tiquetage durable. L’\u00e9tiquetage des appareils simples est normalement effectu\u00e9 par le fabricant.<\/li>\n
  • Assemblage : il s’agit d’une combinaison pr\u00e9fabriqu\u00e9e d’\u00e9quipements Ex et de composants Ex, ainsi que d’autres \u00e9l\u00e9ments, qui sont interconnect\u00e9s \u00e9lectriquement ou m\u00e9caniquement et qui sont pr\u00e9assembl\u00e9s avant d’\u00eatre mis en service sur le site de l’utilisateur final.
    \nComposants exclus. Certains produits sont exclus de la directive Atex car ils ne sont pas consid\u00e9r\u00e9s comme une source d’inflammation. Par exemple, les escaliers, les outils manuels tels que les marteaux ou les vannes manuelles.<\/li>\n<\/ul>\n

    L’autre concept cl\u00e9 est que, \u00e0 l’exception des appareils simples, seuls les \u00e9quipements Ex disposant d’un certificat Ex peuvent \u00eatre utilis\u00e9s \u00e0 l’int\u00e9rieur d’une zone class\u00e9e.<\/p>\n

    Veuillez garder \u00e0 l’esprit qu’un ensemble d’\u00e9quipements Ex peut comporter des parties de l’ensemble pr\u00e9sentant des sp\u00e9cifications de protection contre les explosions diff\u00e9rentes. Par exemple, une partie de l’ensemble d’\u00e9quipements peut n\u00e9cessiter un EPL Gb (Zone 1) et le reste un EPL Gc (Zone 2), ou une partie de l’ensemble d’\u00e9quipements peut n\u00e9cessiter un EPL Gc (Zone 2) et le reste \u00eatre non dangereux.<\/p>\n

    L’autre aspect important est que la zone classifi\u00e9e peut \u00eatre \u00ab externe \u00bb \u00e0 l’ensemble ou g\u00e9n\u00e9r\u00e9e par l’ensemble lui-m\u00eame. En d’autres termes, deux aspects de la classification des zones peuvent avoir un impact sur les ensembles d’\u00e9quipements. Ces aspects sont les suivants :<\/p>\n

      \n
    • Une source potentielle de rejet externe \u00e0 l’ensemble d’\u00e9quipements, ou<\/li>\n
    • Une source potentielle de rejet associ\u00e9e \u00e0 l’ensemble d’\u00e9quipements.<\/li>\n<\/ul>\n
