EN 60079-6:2015

Explosive atmospheres - Part 6: Equipment protection by liquid immersion "o"

IEC 60079-6:2015 specifies the requirements for the design, construction, testing and marking of Ex Equipment and Ex Components with type of protection liquid immersion "o" intended for use in explosive gas atmospheres. Ex Equipment and Ex Components of type of protection liquid immersion "o" are either: - Level of Protection "ob" (EPL "Mb" or "Gb") or - Level of Protection "oc" (EPL "Gc"). For Level of Protection "ob", this standard applies where the rated voltage does not exceed 11 kV r.m.s. a.c. or d.c. For Level of Protection "oc", this standard applies where the rated voltage does not exceed 15 kV r.m.s. a.c. or d.c. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. This fourth edition cancels and replaces the third edition, published in 2007. This edition constitutes a technical revision. The significant changes with respect to the previous edition are: - Edition 4 represents a major technical revision of the requirements for oil immersion "o" and should be considered as introducing all new requirements. The normal "Table of Significant Changes" has not been included for this reason. In particular: - The requirements for oil immersion "o" have been redefined into liquid immersion, levels of protection "ob" and "oc" as recommended by the responses to 31/715/DC; - The ability to protect sparking contacts has been added to both "ob" and "oc". Additional requirements have been introduced for the protective liquid. Keywords: Ex Equipment and Ex Components with type of protection liquid immersion "o"

Explosionsgefährdete Bereiche - Teil 6: Geräteschutz durch Flüssigkeitskapselung "o"

Atmosphères explosives - Partie 6: Protection du matériel par immersion dans le liquide "o"

L'IEC 60079-6:2015 spécifie les exigences de conception, de construction, d'essais et de marquage d'un matériel Ex et de composants Ex, de mode de protection immersion dans le liquide "o", destinés à être utilisés dans des atmosphères explosives gazeuses. Un matériel Ex et des composants Ex de mode de protection immersion dans le liquide "o" peuvent être du: Niveau de Protection "ob" (EPL "Mb" ou "Gb"), ou Niveau de Protection "oc" (EPL "Gc"). Pour le Niveau de Protection "ob", la présente norme s'applique si la tension assignée est inférieure à 11 kV eff. c.a. ou c.c. Pour le Niveau de Protection "oc", la présente norme s'applique si la tension assignée est inférieure à 15 kV eff. c.a. ou c.c. La présente norme complète et modifie les exigences générales de l'IEC 60079-0. Lorsqu'une exigence de la présente norme entre en contradiction avec une exigence de l'IEC 60079-0, l'exigence de la présente norme prévaut. Cette quatrième édition annule et remplace la troisième édition parue en 2007. Cette édition constitue une révision technique. Les modifications majeures par rapport à l'édition précédente sont énumérées ci-dessous: - Cette quatrième édition introduit une révision technique majeure des exigences relatives à l'immersion dans l'huile "o", et il convient qu'elle soit considérée comme spécifiant de nouvelles exigences. Le "Tableau des modifications majeures" habituel n'a pas été inclus pour cette raison. En particulier: - Les exigences relatives à l'immersion dans l'huile "o" traitent désormais de l'immersion dans un liquide, de niveaux de protection "ob" et "oc", selon les recommandations des réponses au document 31/715/DC; - La capacité à protéger les contacts à décharge disruptive a été ajoutée aux niveaux de protection "ob" et "oc". Des exigences supplémentaires relatives au liquide de protection ont été introduites. Mots clés: matériel Ex et de composants Ex, de mode de protection immersion dans le liquide "o"

Eksplozivne atmosfere - 6. del: Zaščita opreme s potopitvijo v olje "o" (IEC 60079-6:2015)

Ta del standarda IEC 60079 določa zahteve za načrtovanje, konstrukcijo, preskušanje in označevanje opreme in komponent EX z zaščito s potopitvijo v olje »o«, ki je namenjena uporabi v eksplozivnih plinskih atmosferah.
Oprema in komponente Ex z zaščito s potopitvijo v olje »o« imajo:
• nivo zaščite »ob« (EPL »Mb« ali »Gb«)
• nivo zaščite »oc« (EPL »Gc«)
V okviru nivoja zaščite »ob« se ta standard uporablja, če efektivna izmenična ali enosmerna napetost ne presega 11 kV.
V okviru nivoja zaščite »oc« se ta standard uporablja, če efektivna izmenična ali enosmerna napetost ne presega 15 kV.
OPOMBA: Zahteve za višje napetosti so v obravnavi.
Ta standard dopolnjuje in spreminja splošne zahteve standarda IEC 60079-0. Kadar je zahteva iz tega standarda v nasprotju z zahtevo iz standarda IEC 60079-0, ima prednost zahteva iz tega standarda.
