Industrial electroheating installations - Test methods for infrared electroheating installations

Industrial electroheating installations - Test methods for infrared electroheating installations

IEC 62693:2013 specifies test procedures, conditions and methods according to which the main parameters and the main operational characteristics of industrial infrared electroheating installations are established. A 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.

Industrielle Elektrowärmeanlagen - Prüfverfahren für Infrarot-Elektrowärmeanlagen

Installations électrothermiques industrielles - Méthodes d'essais relatives aux installations électrothermiques par rayonnement infrarouge

La CEI 62693:2013 spécifie les procédures d'essais, les conditions et méthodes d'essais selon lesquelles sont établis les principaux paramètres et les principales caractéristiques de fonctionnement des installations électrothermiques industrielles par rayonnement infrarouge. Une limitation du domaine d'application réside dans le fait que les émetteurs de rayonnement infrarouge comportent une émission spectrale maximale aux longueurs d'onde supérieures à 780 nm dans l'air ou dans le vide, et émettent des spectres continus à large bande tels que par le rayonnement thermique ou les arcs à haute pression.

Industrijske naprave za električno ogrevanje - Metode za preskušanje naprav za električno ogrevanje z infrardečim sevanjem (IEC 62693:2013)

Ta mednarodni standard določa preskusne postopke, pogoje in metode, po katerih so vzpostavljeni glavni parametri in glavne značilnosti delovanja industrijskih naprav za električno ogrevanje z infrardečim sevanjem. 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. V industrijskih napravah za električno ogrevanje z infrardečim sevanjem tako sevanje običajno ustvarjajo infrardeča sevala in občutno presega toplotno konvekcijo ali toplotno prevodnost kot način za prenos toplote v delovno obremenitev. Standard IEC 60519-1:2010 infrardeče sevanje določa kot optično sevanje na frekvenčnem območju med 400 THz in 300 GHz. To ustreza razponu valovnih dolžin od 780 nm do 1 mm v vakuumu. Pri industrijskem infrardečem ogrevanju se običajno 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. Inštalacije, ki spadajo na področje uporabe tega standarda, običajno v skladu z Joulovim zakonom pretvarjajo električno energijo iz enega vira ali več v infrardeče sevanje, ki se oddaja v delovno obremenitev. Taka infrardeča sevala so še zlasti: – toplotna infrardeča sevala iz cevaste, ploščate ali poljubno oblikovane keramike z uporovnim elementom v notranjosti; – infrardeča sevala z vročo žarilno nitko kot virom sevanja, tj. rešetke iz kvarčnega stekla ali halogenske sijalke; – neizolirani elementi iz molibden disilicida, silicijevega karbida ali drugih primerljivih materialov; – uporovni kovinski grelni elementi, proizvedeni npr. iz nikljevih zlitin ali iz železo-kromovo-aluminijeve zlitine; – električne sijalke širokega spektra. Ta standard ne velja za: – inštalacije z glavnim virom infrardečega sevanja v obliki laserjev ali svetlečih diod (LED) – zajemajo jih IEC 62471:2006, IEC 60825-1:2007 in IEC/TR 60825-9:1999; – aparati za splošno uporabo; – aparati za laboratorijsko uporabo – zajema jih 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 skupno električno močjo infrardečih seval, manjšo od 250 W; – ročna oprema z infrardečim sevanjem. Preskusi so namenjeni za zagotovitev poštene primerjave zmogljivosti inštalacij istega razreda. Preskusi, ki se nanašajo na varnost inštalacij, so določeni v standardu IEC 60519-12:2013. Preskusi, ki se nanašajo na zmogljivost infrardečih seval za električno ogrevanje, so določeni v standardu IEC 62798:- . Ta standard se torej uporablja za pečice in peči z uporovnimi grelnimi elementi, če spadajo na področje uporabe tega standarda.

INDUSTRIAL ELECTROHEATING INSTALLATIONS –
TEST METHODS FOR INFRARED ELECTROHEATING INSTALLATIONS

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

Safety in installations for electroheating and electromagnetic processing - Part 6: Particular requirements for high frequency dielectric and microwave heating and processing equipment
SIST EN IEC 60519-6:2024

This part of IEC 60519 is applicable to equipment using high frequency or microwave energy alone or in combination with other kinds of energy for industrial heating and processing of materials. It is also applicable to HF and MW generators made available to users as separate units. This part is applicable to equipment operating in the frequency range 3 MHz to 300 GHz, with the following limitations. - This document applies to only high frequency dielectric heating and processing as defined in 3.1.103. It does not apply to induction heating, which it is possible to carry out in the lower part of the specified frequency band and is covered by IEC 60519-3, with magnetic field safety aspects addressed in IEC TS 62997:2017, the latter to be replaced by a technical report (TR) or by a revised technical specification (TS). - The ISM centre frequencies for dielectric heating and processing of industrial interest are narrow bands about 6,78 MHz, 13,56 MHz, 27,12 MHz and 40,68 MHz. Different field emission measurement procedures and limiting values are applicable, depending on the processing frequency in the high frequency range 3 to 300 MHz. Specifications are in Annex BB. - This document specifies limits for microwave emission only for the ISM frequencies between 800 MHz and 6 MHz, as specified in Annex CC. For other microwave frequencies the basic restriction and IEC 62311 apply. - The foundations for compliance with emission values are the basic restrictions, referred to in the IEEE/ANSI C95.1:2019 and Directive 2013/35/EU. However, maximum HF processing frequency electric and magnetic field values are taken from the IEEE/ANSI C95.1:2019 standard, as indicated in Annex BB. - This document is not applicable to: -- appliances for household and similar use (covered by e.g. IEC 60335-2-25); -- commercial use (covered by IEC 60335-2-90 and IEC 60335-2-110); -- laboratory use (covered by IEC 61010-2-010); -- medical high frequency equipment and accessories (covered by IEC 60601-2-2). NOTE 101 Since high frequency and microwave tunnel ovens and also some other types of microwave and high frequency equipment are sometimes intended either for commercial, laboratory or industrial use, the following criteria are suitable for determination of the classification as industrial equipment: - commercial equipment is typically designed and planned for series production of many identical units, whereas industrial equipment is typically produced in small series or even as single units. The processed goods are consumed or ready for final use at the end of the heating process. - laboratory heating equipment is for preparing material in a laboratory environment, and the processed material is immediately available for investigations or further processing. Regular production of large quantities of material is not foreseen. - with industrial equipment, the processed goods are not immediately accessible to the end user, and the goods are sometimes not in a final state from the perspective of the end user.

The rated voltage of arc furnace installation can be in the range of low voltage or high voltage, details are given in 4.2. This standard is applicable to arc furnace installations such as: a) furnaces for direct arc heating, forming arcs between the electrode and metal such as the electric arc furnace using alternating current (EAF AC) or direct current (EAF DC), and the ladle furnace (LF); b) furnaces for arc-resistance heating forming arcs between the electrode and the charge material or heating the charge material by the Joule effect, such as the submerged arc resistance furnace using alternating current (SAF AC), or direct current (SAF DC). NOTE In some documents the terms smelter or electrical reduction furnace are used. Furnace installation for unattended operation is not covered by this standard. 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. With respect to noise of electrical an arc furnace, ISO 13578:2017, 6.1.23 applies.
