Annotation of standard text IEC 60079-7-ed.5.1+Amd.1-CSV :
IEC 60079-7:2015+A1:2017 specifies the requirements for the design, construction, testing and marking of electrical equipment and Ex Components with type of protection increased safety "e" intended for use in explosive gas atmospheres. Electrical equipment and Ex Components of type of protection increased safety "e" are either: - level of Protection "eb" (EPL "Mb" or "Gb"); or - level of Protection "ec" (EPL "Gc"). Level of Protection "eb" applies to equipment or Ex Components, including their connections, conductors, windings, lamps, and batteries; but not including semiconductors or electrolytic capacitors. Level of Protection "ec" applies to equipment or Ex Components, including their connections, conductors, windings, lamps, and batteries; and also including semiconductors and electrolytic capacitors. The requirements of this standard apply to both Levels of Protection unless otherwise stated. For Level of Protection "eb", this standard applies to electrical equipment where the rated voltage does not exceed 11 kV r.m.s., a.c. or d.c. For Level of Protection "ec", this standard applies to electrical equipment 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 fifth edition cancels and replaces the fourth edition published in 2006, and constitutes a technical revision. Refer to the Foreword of the document for a complete listing of the technical changes between edition 5.0 and previous edition of the document. The contents of the Interpretation sheet 1 of September 2016 have been included in this copy. This consolidated version of the official IEC Standard and its amendment contains the fifth edition (2015) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication. LIEC 60079-7:2015+A1:2017 specifie les exigences specifiques de conception, de construction, dessais et de marquage du materiel electrique et des composants Ex avec mode de protection de securite augmentee "e" destines a etre utilises dans les atmospheres explosives gazeuses. Le materiel electrique et les composants Ex de mode de protection de securite augmentee "e" sont: - dun niveau de protection "eb" (EPL "Mb" ou "Gb"); ou - dun niveau de protection "ec" (EPL "Gc"). Le niveau de protection "eb" sapplique au materiel ou aux composants Ex, y compris leurs connexions, conducteurs, enroulements, lampes et batteries; mais ninclut pas les semi-conducteurs ou les condensateurs electrolytiques. Le niveau de protection "ec" sapplique au materiel ou aux composants Ex, y compris leurs connexions, conducteurs, enroulements, lampes et batteries; cela inclut egalement les semi-conducteurs ou les condensateurs electrolytiques. Sauf indication contraire, les exigences de la presente norme sappliquent aux deux niveaux de protection. Pour le niveau de protection "eb", la presente norme sapplique au materiel electrique si la tension assignee nest pas superieure a une valeur efficace de 11 kV, c.a. ou c.c. Pour le niveau de protection "ec", la presente norme sapplique au materiel electrique si la tension assignee nest pas superieure a une valeur efficace de 15 kV, c.a. ou c.c. La presente norme complete et modifie les exigences generales de lIEC 60079-0. Lorsquune exigence de la presente norme entre en conflit avec une exigence de lIEC 60079-0, lexigence de la presente norme prevaut. Cette cinquieme edition annule et remplace la quatrieme edition parue en 2006. Cette edition constitue une revision technique. Reportez-vous a lavant-propos du document pour une liste complete des modifications techniques entre ledition 5.0 et edition precedente du document. Mots cles: materiel electrique et des composants Ex avec mode de protection de securite augmentee "e" destines a etre utilises dans les atmospheres explosives gazeuses Le contenu de la feuille dinterpretation 1 de septembre 2016 a ete pris en consideration dans cet exemplaire. Cette version consolidee de la Norme IEC officielle et de son amendement contient la cinquieme edition (2015) et son amendement 1 (2017). Il nest donc pas necessaire de commander lamendement avec cette publication.
