(Main)Safety in installations for electroheating and electromagnetic processing - Part 1: General requirements
Safety in installations for electroheating and electromagnetic processing - Part 1: General requirements
This part of IEC 60519 specifies 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).
The requirements are applicable to industrial installations or equipment with the possible use
as:
– equipment for direct and indirect resistance heating,
– equipment for electric resistance trace heating,
– equipment for induction heating,
– equipment using the effect of electromagnetic forces on materials,
– equipment for arc heating, including submerged arc heating,
– equipment for electroslag remelting,
– equipment for plasma heating and plasma surface treatment,
– equipment for microwave heating,
– equipment for dielectric heating,
– equipment using electron guns,
– equipment for infrared radiation heating,
– equipment for laser heating.
NOTE The list presents typical examples of equipment and its applications and is not exhaustive.
The overall safety requirements for the various types of EH or EPM equipment and
installations result from the joint application of the General Requirements specified in this
standard and Particular Requirements covering specific types of installations or equipment
(guidelines are given in Annex G). If no Particular Requirement is covering a specific
installation or equipment, the General Requirements are applicable as such.
This standard does not apply to equipment and appliances within the scope of:
– IEC 60079 series – i.e. equipment or installations intended for use in potentially explosive
atmospheres;
– IEC 60335 series, – i.e. household, commercial and similar electrical appliances, including
room heating;
– IEC 60601 series – i.e. medical electrical equipment,
– IEC 60974 series – i.e. arc welding equipment,
– IEC 61010 series – i.e. equipment for laboratory use.
Sicherheit in Elektrowärmeanlagen und Anlagen für elektromagnetische Bearbeitungsprozesse - Teil 1: Allgemeine Anforderungen
Sécurité dans les installations destinées au traitement électrothermique et électromagnétique - Partie 1: Exigences générales
L'IEC 60519-1:2015 spécifie les exigences de sécurité générales relatives aux installations ou équipements industriels destinés à l'électrothermie (EH) et aux technologies de traitement basées sur l'électrothermie ainsi qu'au traitement électromagnétique des matériaux (EPM).

a) Le titre et le domaine d'application de la norme ont été étendus pour inclure les installations et les équipements destinés au traitement électromagnétique des matériaux.
b) les équipements destinés au traitement électromagnétique des matériaux. Les termes et définitions, ainsi que la liste des références normatives, ont été mis à jour et complétés par de nouveaux éléments.
c) Les exigences ont été restructurées.
d) Des exigences supplémentaires relatives aux champs électriques et magnétiques, aux courants de contact, ainsi qu'aux rayonnements optiques, ont été ajoutées.
e) De nouveaux articles traitant de la vérification ont été ajoutés.
f) De nouvelles annexes spécifiant les limites des dangers d'exposition aux champs électriques et magnétiques, au rayonnement optique, au bruit et aux vibrations ont été ajoutées.
g) De nouvelles annexes sur la CEM, les marquages et avertissements, les lignes directrices pour l'utilisation de la présente norme et des informations concernant le lien avec l'ISO 13577-1 ont été ajoutées.
Varnost pri električnih grelnih inštalacijah in elektromagnetni obdelavi - 1. del: Splošne zahteve
Ta del standarda IEC 60519 določa splošne varnostne zahteve za industrijske naprave ali opremo, namenjeno obdelovalnim tehnologijam za električno ogrevanje (EH) in na podlagi električnega ogrevanja ter za elektromagnetno obdelavo materialov (EPM).
Zahteve se uporabljajo za industrijske naprave ali opremo, ki se lahko uporablja kot:
– oprema za neposredno in posredno uporovno gretje,
– oprema za električne uporovne grelne trake,
– oprema za indukcijsko gretje,
– oprema, ki izkorišča učinek elektromagnetnih sil na materiale,
– oprema za obločno gretje, vključno z zakritim obločnim gretjem,
– oprema za pretaljenje pod električno prevodno žlindro,
– opremo za plazemsko gretje in površinsko obdelavo s plazmo,
– oprema za mikrovalovno gretje,
– oprema za dielektrično gretje,
– oprema, ki uporablja elektronske pištole,
– oprema za infrardeče sevalno gretje,
– oprema za lasersko gretje.
OPOMBA: Seznam predstavlja običajne primere opreme in njenih uporab ter ni izčrpen. Splošne varnostne zahteve za različne vrste opreme in naprav za električno ogrevanje ali elektromagnetno obdelavo materialov izhajajo iz skupne uporabe splošnih zahtev, opredeljenih v tem standardu, ter posebnih zahtev, ki zajemajo posebne vrste naprav ali opreme (smernice so podane v dodatku G). Če posamezne naprave ali opreme ne zajema nobena posebna zahteva, se kot take uporabljajo splošne zahteve. Ta standard se ne uporablja za opremo in naprave v okviru skupin standardov:
– IEC 60079, tj. opremo ali naprave, namenjene uporabi v potencialno eksplozivnih atmosferah;
– IEC 60335, tj. gospodinjske, komercialne in podobne električne aparate, vključno z aparati za sobno ogrevanje;
– IEC 60601, tj. medicinsko električno opremo;
– IEC 60974, tj. opremo za obločno varjenje;
– IEC 61010, tj. opremo za laboratorijsko uporabo.
