Explosive atmospheres - Part 19: Equipment repair, overhaul and reclamation (IEC 60079-19:2019)

EN-IEC 60079-19 gives instructions, principally of a technical nature, on the repair, overhaul, reclamation and modification of Ex equipment designed for use in explosive atmospheres; - applies to overhaul and repair which mitigates deficiencies identified during operation, inspection and maintenance; - does not give advice on cable and wiring systems which can require a renewal when the equipment is re-installed; and - is not applicable to Type of Protection “m”.

Explosionsgefährdete Bereiche - Teil 19: Gerätereparatur, Überholung und Regenerierung (IEC 60079-19:2019)

Atmosphères explosives - Partie 19: Réparation, révision et remise en état de l'appareil (IEC 60079-19:2019)

IEC 60079-19:2019 donne des instructions, principalement de nature technique, pour la réparation, la révision, la remise en état et la modification de l’appareil Ex conçu pour être utilisé en atmosphères explosives. Il s’applique à la révision et à la réparation qui atténuent les déficiences identifiées en fonctionnement et lors d’opérations d’inspection et de maintenance. Il ne fournit pas de conseils sur les systèmes de câblage qui peuvent exiger un renouvellement quand l’appareil est réinstallé, et il n’est pas applicable au mode de protection “m”. Cette quatrième édition annule et remplace la troisième édition parue en 2010, ainsi que l’Amendement 1:2015. Cette édition constitue une révision technique. L’importance des modifications entre l’IEC 60079-19, Édition 3 (2010), y compris l’Amendement 1 (2015), et l’IEC 60079-19, Édition 4 (2019) est indiquée comme modifications mineures et rédactionnelles, extension et modifications techniques majeures.
