Anotation

IEC 60079-18:2025 gives the specific requirements for the construction, testing and marking of electrical Ex Equipment, parts of electrical Ex Equipment and Ex Components with the Type of Protection encapsulation "m" (hereinafter referred to as "m" Equipment) intended for use in explosive gas atmospheres or explosive dust atmospheres. For Levels of Protection "mb" and "mc", this document applies where the rated voltage does not exceed 11 kV ACRMS or DC. For Level of Protection "ma", this document applies where the rated voltage does not exceed 1 kV ACRMS or DC. This document does not take account of any hazard due to an emission of flammable or toxic gas from the dust. This document supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this document conflicts with a requirement of IEC 60079-0, the requirement of this document takes precedence. This fifth edition cancels and replaces the fourth edition published in 2014 and Amendment 1:2017. This edition constitutes a technical revision. This International Standard is to be used in conjunction with IEC 60079-0, Explosive atmospheres - Part 0: Equipment - General requirements. Users of this document are advised that interpretation sheets clarifying the interpretation of this document can be published. Interpretation sheets are available from the IEC webstore and can be found in the "history" tab of the page for each document. Please see the foreword to this document for the list of significant technical changes with respect to the previous edition. IEC 60079-18:2025 definit les exigences specifiques a la construction, aux essais et au marquage de l’appareil Ex electrique, des parties de l’appareil Ex electrique et des composants Ex proteges par encapsulage "m" (ci-apres designes appareils "m") et destines a une utilisation dans les atmospheres explosives gazeuses ou les atmospheres explosives de poussiere. Pour les niveaux de protection "mb" et "mc", le present document s’applique lorsque la tension assignee ne depasse pas 11 kV en courant alternatif efficace ou en courant continu. Pour le niveau de protection "ma", le present document s’applique lorsque la tension assignee ne depasse pas 1 kV en courant alternatif efficace ou en courant continu. Le present document ne tient pas compte des dangers, quels qu’ils soient, resultant d’une emission de gaz inflammable ou toxique provenant de la poussiere. Le present document complete et modifie les exigences generales de l’IEC 60079-0. Si une exigence du present document est en conflit avec une exigence de l’IEC 60079-0, l’exigence du present document prevaut. Cette cinquieme edition annule et remplace la quatrieme edition parue en 2014, ainsi que l’Amendement 1:2017. Cette edition constitue une revision technique. Cette Norme internationale doit etre utilisee conjointement avec l’IEC 60079-0, Atmospheres explosives - Partie 0: Materiel - Exigences generales. Les modifications techniques majeures suivantes par rapport a l’edition precedente se trouvent en avant-propos.
