IEC 60519-1:2020 is available as IEC 60519-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.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).
