Safety in installations for electroheating and electromagnetic processing - Part 12: Particular requirements for infrared electroheating
IEC 60519-12:2016 specifies safety requirements for industrial electroheating equipment and installations in which infrared radiation – usually generated by infrared emitters – is significantly dominating over heat convection or heat conduction as means of energy transfer to the workload. A further limitation of the scope is that the infrared emitters have a maximum spectral emission at longer wavelengths than 780 nm in air or vacuum, and are emitting wideband continuous spectra such as by thermal radiation or high pressure arcs. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a. the structure has been redrafted according to IEC 60519-1:2015; b. terms/definitions, normative references and bibliography have been updated and completed; c. all requirements and content from IEC 60519-12:2013 that have been included in IEC 60519-1:2015 have been removed to avoid any duplication.

Sécurité dans les installations destinées au traitement électrothermique et électromagnétique - Partie 12: Exigences particulières pour chauffage électrique par rayonnement infrarouge
L’IEC 60519-12:2016 spécifie les exigences de sécurité concernant les équipements et installations électrothermiques industriels avec lesquels le rayonnement infrarouge, produit habituellement par des émetteurs de rayonnement infrarouge, prédomine véritablement sur la convection ou la conduction thermique comme moyen de transfert d'énergie à la charge de travail. Une limite supplémentaire du domaine d'application se traduit par le fait que les émetteurs de rayonnement infrarouge ont une émission spectrale maximale à des longueurs d’onde plus grandes que 780 nm dans l'air ou le vide, et émettent des spectres continus à large bande tels que ceux émis par un rayonnement thermique ou des arcs à haute pression. Cette deuxième édition annule et remplace la première édition parue en 2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a. la structure du présent document a été alignée sur celle de l’IEC 60519-1:2015; b. les termes/définitions, les références normatives ainsi que la bibliographie ont été mis à jour et complétés; c. toutes les exigences et le contenu de l’IEC 60519-12:2013 repris dans l’IEC 60519-1:2015 ont été supprimés pour éviter les répétitions.
Varnost pri električnih grelnih inštalacijah in elektromagnetni obdelavi - 12. del: Posebne zahteve za inštalacije z infrardečim električnim ogrevanjem
IEC 60519 določa posebne varnostne zahteve za industrijsko električno grelno opremo in inštalacije, v katerih infrardeče sevanje, ki ga ponavadi ustvarijo infrardeča sevala, občutno presega toplotno konvekcijo ali toplotno prevodnost, kar zadeva prenos energije v delovno obremenitev. Dodatna omejitev področja uporabe na infrardeča sevala, ki imajo najvišjo spektralno emisijo pri valovnih dolžinah, daljših od 780 nm, v zraku ali vakuumu in oddajajo neprekinjene širokopasovne spektre, kakor pri lokih toplotnega sevanja ali visokega tlaka. Standard IEC 60519-1:2015 opredeljuje infrardeče sevanje kot sevanje na frekvenčnem območju med 400 THz in 300 GHz. To ustreza razponu valovnih dolžin od 780 nm do 10 μm v vakuumu. Pri industrijskem infrardečem ogrevanju se ponavadi uporabljajo viri infrardečega sevanja z nazivnimi temperaturami med 500 in 3000 °C; sevanje, oddano iz teh virov, je predvsem v razponu valovnih dolžin od 780 nm do 10 μm. Znatni del emisij iz toplotnih seval lahko sega pod 780 nm ali nad 3000 nm, zato so v tem dokumentu upoštevani tudi varnostni vidiki za oddano vidno svetlobo in emisije pri valovnih dolžinah, daljših od 3000 nm. Ta standard se ne uporablja za: – inštalacije z glavnim virom infrardečega sevanja v obliki laserjev ali svetlečih diod (LED) – zajemata jih standarda IEC 62471:2006 in IEC 60825-1:2014; – aparati za splošno uporabo; – aparati za laboratorijsko uporabo – zajema jih standard IEC 61010-1:2010; – inštalacije za električno ogrevanje, v katerih se kot grelni elementi uporabljajo uporovne žice, cevi ali palice in infrardeče sevanje ni prevladujoč stranski učinek predvidene uporabe, ki jih zajema standard IEC 60519-2:2006; – oprema z infrardečim ogrevanjem z nominalnim združenim električnim tokom infrardečih seval, manjšim od 250 W; – ročna oprema z infrardečim sevanjem. Industrijska oprema z infrardečim električnim ogrevanjem, ki spada na področje uporabe tega standarda, običajno v skladu z Joulovim zakonom pretvarja električno energijo v infrardeče sevanje iz enega ali več virov. Eden ali več elementov nato oddajo sevanje v material, ki bo obdelan. Takšni elementi infrardečega ogrevanja so predvsem: – toplotna infrardeča sevala iz cevaste, ploščate ali poljubno oblikovane keramike z upornim elementom v notranjosti; – infrardeča sevala z vročo žarilno nitko kot virom sevanja, tj. rešetke iz kvarčnega stekla ali halogenske sijalke; – neizolirani elementi iz molibdenovega disilicida, silicijevega karbida, grafita, železo-kromovo-aluminijeve zlitine, težkotaljivih materialov ali primerljivih materialov; – električne sijalke širokega spektra.

Part 12: Particular requirements for infrared electroheating
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out
