(Main)Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
This part of the IEC 60079 series applies to users and covers only those factors directly related to the inspection and maintenance of electrical installations specifically designed for hazardous areas, where the hazard may be caused by explosive gas or explosive dust atmospheres. It does not include: - other fundamental installation and inspection requirements for electrical installations; - the verification of electrical equipment; - protection or ventilation of rooms; - gas detection systems; - the repair and overhaul of explosion protected equipment (see IEC 60079-19). While this standard does not include inspection of safety devices such as used in ventilated rooms (see 60079-13), this standard does include the requirements for inspection and maintenance of individual items of equipment that will be part of such systems, for example motors or sensors. This standard supplements the requirements for inspection and testing in non-hazardous areas in IEC 60364-6. NOTE 1 Standards applied at the date of installation might not have been IEC standards. 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, - pyrophoric substances.

Atmosphères explosives - Partie 17 : Inspection et maintenance des installations électriques
IEC 60079-17:2023 est disponible sous forme de IEC 60079-17:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60079-17:2023 s’applique aux utilisateurs et couvre uniquement les facteurs directement liés à l’inspection et à la maintenance des installations électriques spécialement conçues pour les emplacements dangereux, où le danger provient des atmosphères explosives. Elle ne comprend pas: - les autres exigences fondamentales relatives à l’installation et à l’inspection pour les installations électriques; - la vérification des appareils électriques; - la protection ou la ventilation des salles; - les systèmes de détection de gaz; - les réparations, les révisions et la remise en état des appareils protégés contre l’explosion (voir IEC 60079-19). Bien que le présent document n’inclue pas l’inspection des dispositifs de sécurité tels que ceux utilisés dans les salles ventilées (voir IEC 60079-13), il inclut les exigences relatives à l’inspection et à la maintenance de chacun des éléments des appareils qui font partie de ces systèmes, par exemple les moteurs ou les capteurs. Le présent document constitue un complément pour les exigences relatives aux inspections et aux essais de l’IEC 60364-6 effectués dans des emplacements non dangereux. Le présent document est destiné à être appliqué s’il existe un risque dû à la présence potentielle de gaz explosifs, de mélanges de poussières dans l’air ou de couches de poussières combustibles dans des conditions atmosphériques normales. Il ne s’applique pas: - aux parties souterraines des mines; - aux poussières d’explosifs; - aux substances pyrophoriques. Cette sixième édition annule et remplace la cinquième édition parue en 2013. Cette édition constitue une révision technique.
Eksplozivne atmosfere - 17. del: Pregledovanje in vzdrževanje električnih inštalacij (IEC 60079-17:2023)
Ta del skupine standardov IEC 60079 se uporablja za uporabnike in zajema samo tiste dejavnike, ki so neposredno povezani s pregledovanjem in vzdrževanjem električnih inštalacij, zasnovanih izključno za nevarna območja, kjer lahko nevarnost povzročijo eksplozivne plinske atmosfere ali eksplozivne prašne atmosfere.
Ta del ne vključuje:
– drugih temeljnih zahtev nameščanja in pregledovanja za električne inštalacije;
– preverjanja električne varnosti;
– zaščite ali prezračevanja prostorov;
– sistemov za odkrivanje plinov;
– popravil in remonta opreme, zaščitene pred eksplozijami (glej standard IEC 60079-19).
Medtem ko ta standard ne zajema pregleda varnostnih naprav, na primer za uporabo v prezračevanih prostorih (glej standard 60079-13), pa vključuje zahteve za pregledovanje in vzdrževanje posameznih elementov opreme, ki bo del tovrstnih sistemov, na primer motorji ali senzorji.
Ta standard dopolnjuje zahteve za pregledovanje in preskušanje v nenevarnih območjih iz standarda IEC 60364-6.
OPOMBA 1: Standardi, ki se uporabljalo na datum namestitve, morda niso standardi IEC.
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:
– območja za podzemno rudarjenje,
– prah eksplozivov,
– piroforne snovi.
