IEC 60519-1:2020

Safety in installations for electroheating and electromagnetic processing - Part 1: General requirements

IEC 60519-1:2020 specifies the general safety requirements for industrial installations or equipment intended for electroheating (EH) and electroheating based treatment technologies as well as for electromagnetic processing of materials (EPM). This document deals with the significant hazards, hazardous situations or hazardous events relevant to industrial EH and EPM equipment, as listed in Annex A, for normal operation and for single fault condition as well as under conditions of reasonably foreseeable misuse. This sixth edition cancels and replaces the fifth edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- removal of noise from the scope;
- clarification of EMC requirements;
- risk classification of hazards based on emission for all processing frequencies;
- clarification of boundaries between IEC 60519 (all parts) and ISO 13577 (all parts).

Sécurité dans les installations destinées au traitement électrothermique et électromagnétique - Partie 1: Exigences générales

L’IEC 60519-1:2020 spécifie les exigences générales de sécurité relatives aux installations ou équipements industriels destinés à l’électrothermie (EH) et aux technologies de traitement fondées sur l’électrothermie ainsi qu’au traitement électromagnétique des matériaux (EPM). Le présent document traite des dangers significatifs, des situations dangereuses ou des événements dangereux liés aux équipements industriels EH et EPM, tels qu’ils sont répertoriés dans l’Annexe A, dans des conditions de fonctionnement normal et en condition de premier défaut ainsi que dans des conditions de mauvaise utilisation raisonnablement prévisibles. Cette sixième édition annule et remplace la cinquième édition parue en 2015. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
- suppression du bruit du domaine d’application;
- clarification des exigences relatives à la CEM;
- classification des risques associés aux dangers, fondée sur l’émission pour toutes les fréquences de traitement;
- clarification des limites entre l’IEC 60519 (toutes les parties) et l’ISO 13577 (toutes les parties).
