Safety in installations for electroheating and electromagnetic processing - Part 1: General requirements (IEC 60519-1:2020)

This part of IEC 60519 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 document specifies the requirements intended to be met by the manufacturer to ensure
the safety of persons and property during the complete life cycle of the equipment from design
through commissioning, operation, maintenance, inspection, to decommissioning, as well as
in the event of foreseeable single fault condition that can occur in the equipment.
The rated voltage of EH and EPM equipment can be in the range of low voltage; details are
given in 4.2.
This document does not apply to equipment and appliances within the scope of
– IEC 60079 (all parts) – i.e. equipment intended for use in potentially explosive
atmospheres;
– IEC 60335 (all parts) – i.e. household, commercial and similar electrical appliances,
including room heating;
– IEC 60601 (all parts) – i.e. medical electrical equipment;
– IEC 60974 (all parts) – i.e. arc welding equipment;
– IEC 61010 (all parts) – i.e. equipment for laboratory use.
This document does not provide requirements for type testing.
NOTE Industrial equipment covered by this document is typically produced as a single unit or a very small number
of units; such unit usually has a very high value and can cause severe harm at disintegration.
This document does not address data security and hazards arising from neglect of security.

IEC 60519-1:2020 est disponible sous forme de IEC 60519-1:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.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).

Annex ZZ
(informative)
Relationship between this European standard and the safety objectives of
Directive 2014/35/EU [2014 OJ L96] aimed to be covered

This European Standard has been prepared under a Commission’s standardization request

relating to harmonized standards in the field of the Low Voltage Directive, M/511, to provide

one voluntary means of conforming to safety objectives of Directive 2014/35/EU of the

European Parliament and of the Council of 26 February 2014 on the harmonization of the laws

of the Member States relating to the making available on the market of electrical equipment

designed for use within certain voltage limits [2014 OJ L96].

Once this standard is cited in the Official Journal of the European Union under that Directive,

compliance with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of

the scope of this standard, a presumption of conformity with the corresponding safety objectives of

that Directive, and associated EFTA regulations.
