Anotation

IEC 60079:2024 contains the specific requirements for the design of electrical systems, selection, installation and the required initial inspection of electrical installations of Ex Equipment in, or associated with, explosive atmospheres including requirements for documentation and personnel competency. These requirements are in addition to the requirements for installations in non-hazardous areas. This document applies to all electrical Ex Equipment including fixed, transportable, portable and personal, and installations, permanent or temporary. This document does not apply to: • electrical installations in mines susceptible to firedamp; • inherently explosive situations and dust from explosives or pyrophoric substances (for example explosives manufacturing and processing); • rooms used for medical purposes; • electrical installations in areas where the hazard is due to flammable mist; and • installation of non-electrical Ex Equipment (unless being part of an equipment assembly according IEC TS 60079-46). No account is taken in this document of the toxic hazards that are associated with flammable gases, liquids and dusts in concentrations that are usually very much less than the lower flammable limit. In locations where personnel could be exposed to potentially toxic concentrations of flammable material, appropriate precautions are necessary. Such precautions are outside the scope of this document. This sixth edition cancels and replaces the fifth edition published in 2013. This edition constitutes a technical revision. Edition 6 is a major restructure and introduces a number of technical changes from the previous edition (2013), see Table 1 of the foreword for detailed information. IEC 60079-14:2024 contient les exigences specifiques relatives a la conception de systemes electriques, a la selection, a l’installation et a l’inspection initiale exigee des installations electriques des appareils Ex electriques situes dans des atmospheres explosives, ou associees a celles-ci, comprenant les exigences relatives a la documentation et a la competence du personnel. Ces exigences completent celles relatives aux installations dans les emplacements non dangereux. Le present document s’applique a tout appareil Ex electrique, comprenant les appareils fixes, transportables, portables, et personnels, et aux installations, permanentes ou temporaires. Le present document ne s’applique pas: • aux installations electriques situees dans des mines grisouteuses; • aux situations intrinsequement explosives et aux poussieres issues de substances explosives ou pyrophoriques (la fabrication et le traitement d’explosifs, par exemple); • aux salles utilisees a des fins medicales; • aux installations electriques situees dans des emplacements ou le danger provient d’un brouillard inflammable; et • a l’installation d’appareils Ex non electriques (sauf s’ils font partie d’un assemblage d’appareils conformement a l’IEC TS 60079-46). Le present document ne tient pas compte des dangers toxiques associes aux gaz, liquides et poussieres inflammables presents dans des concentrations habituellement bien inferieures a la limite inferieure d’inflammabilite. Sur les sites ou le personnel est susceptible d’etre expose a des concentrations potentiellement toxiques de matieres inflammables, des precautions appropriees sont necessaires. Ces precautions ne relevent pas du domaine d’application du present document. Cette sixieme edition annule et remplace la cinquieme edition parue en 2013. Cette edition constitue une revision technique. La 6e edition constitue une restructuration majeure et introduit plusieurs modifications techniques par rapport a l’edition precedente (2013). Le Tableau 1, voir AVANT-PROPOS "Tableau des modifications majeures", est fourni afin de mettre en avant les modifications techniques ainsi que les principales modifications redactionnelles par rapport a l’edition precedente.
