(Main)Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
IEC 60079-17:2013 applies to users and covers factors directly related to the inspection and maintenance of electrical installations within hazardous areas only, where the hazard may be caused by flammable gases, vapours, mists, dusts, fibres or flyings. It does not include: - other fundamental installation and inspection requirements for electrical installations; - the verification of electrical equipment; - the repair and reclamation of explosion protected equipment (see IEC 60079-19). This standard supplements the requirements of IEC 60364-6. In the case of dusts, fibres or flyings the level of housekeeping may influence the inspection and maintenance requirements. This standard is intended to be applied where there can be a risk due to the presence of explosive gas or dust mixtures with air or combustible dust layers under normal atmospheric conditions. It does not apply to: - underground mining areas, - dusts of explosives that do not require atmospheric oxygen for combustion, - pyrophoric substances. This fifth edition cancels and replaces the fourth edition published in 2007 and constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows: - Equipment specific inspection tables for luminaires, heating systems and motors have been added into Annex A to supplement the general protection concept tables; - Document has been updated to complement the changes made to IEC 60079-14 for initial inspection. Keywords: inspection and maintenance of electrical installations within hazardous area, flammable gases, vapours, mists, dusts, fibres or flyings

Atmosphères explosives - Partie 17: Inspection et entretien des installations électriques
La IEC 60079-17:2013 applique aux utilisateurs et couvre les facteurs directement liés à l'inspection et à l'entretien des seules installations électriques situées à l'intérieur des emplacements dangereux, où le danger peut venir des gaz, des vapeurs, des brouillards, des poussières, des fibres ou des particules en suspension inflammables. Elle ne comprend pas: - les autres exigences fondamentales relatives à l'installation et à l'inspection pour les installations électriques; - la vérification du matériel électrique; - les réparations et remises en état de matériel protégé contre les explosions (voir CEI 60079-19). La présente norme constitue un complément pour les exigences de la CEI 60364-6. Dans le cas de poussières, fibres ou particules en suspension, le niveau de l'entretien courant peut influencer les exigences d'entretien et d'inspection. La présente norme est destinée à être appliquée lorsqu'il existe un risque dû à la présence de gaz explosifs ou de mélanges de poussières dans l'air ou des couches de poussières combustibles dans des conditions atmosphériques normales. Elle ne s'applique pas: - aux parties souterraines des mines, - aux poussières d'explosifs qui n'exigent pas d'oxygène de l'air pour leur combustion, - aux substances pyrophoriques. Cette cinquième édition annule et remplace la quatrième édition publiée en 2007 et constitue une révision technique. Les modifications techniques importantes par rapport à l'édition antérieure sont indiquées ci-dessous: - Des tableaux relatifs à l'inspection spécifique au matériel pour les luminaires, systèmes de chauffage et moteurs ont été ajoutés dans l'Annexe A afin de compléter les tableaux de concept de protection générale; - Le document a été actualisé pour compléter les modifications apportées à la CEI 60079-14. Mots clés : l'inspection et à l'entretien des installations électriques situées à l'intérieur des emplacements dangereux, gaz, des vapeurs, des brouillards, des poussières, des fibres ou des particules en suspension inflammables
Eksplozivne atmosfere - 17. del: Pregledovanje in vzdrževanje električnih inštalacij
Ta del skupine standardov IEC 60079 velja za uporabnike in zajema dejavnike, neposredno povezane s pregledovanjem in vzdrževanjem električnih napeljav izključno v nevarnih območjih, kjer lahko tveganje povzročijo vnetljivi plini, hlapi, meglice, prah, vlakna ali odpadki iz predilnic. Ta standard ne vključuje: – drugih temeljnih zahtev nameščanja in pregledovanja za električne napeljave, – preverjanja električne opreme, – popravil in reklamacij opreme, zaščitene pred eksplozijami (glejte standard IEC 60079-19). Ta standard dopolnjuje zahteve iz standarda IEC 60364-6. V primeru prahu, vlaken ali odpadkov iz predilnic lahko na zahteve pregledovanja in vzdrževanja vpliva raven vzdrževanja čistoče. Ta standard je namenjen uporabi v primerih tveganja zaradi prisotnosti eksplozivnega plina ali mešanic prahu z zrakom ali gorljivih plasti prahu v običajnih atmosferskih pogojih. Ne uporablja se za: – podzemna rudniška okolja, – prah eksplozivov, ki za zgorevanje ne potrebuje atmosferskega kisika, – piroforne snovi.
