Safety in electroheating installations - Part 12: Particular requirements for infrared electroheating installations

This part of IEC 60519 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 material to be treated. 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. IEC 60519-1:2010 defines infrared as radiation within the frequency range between about 400 THz and 300 GHz. This corresponds to the wavelength range between 780 nm and 1 mm in vacuum. Industrial infrared heating usually uses infrared sources with rated temperatures between 500 °C and 3000 °C; the emitted radiation from these sources dominates in the wavelength range between 780 nm and 10 μm. Since substantial emission of e.g. blackbody thermal emitters may extend beyond 780 nm or 3000 nm, the safety aspects of emitted visible light and emission at wavelengths longer than 3000 nm are also considered in this standard. This standard is not applicable to: - infrared installations with lasers or light-emitting diodes (LEDs) as main sources - they are covered by IEC 62471:2006, IEC 60825-1:2007 and IEC/TR 60825-9:1999; - appliances for use by the general public; - appliances for laboratory use - they are covered by IEC 61010-1:2010; - electroheating installations where resistance heated bare wires, tubes or bars are used as heating elements, and infrared radiation is not a dominant side effect of the intended use, covered by IEC 60519-2:2006; - infrared heating equipment with a nominal combined electrical power of the infrared emitters of less than 250 W; - handheld infrared equipment. Industrial infrared electroheating equipment under the scope of this standard typically uses the Joule effect for the conversion of electric energy into infrared radiation by one or several sources. Radiation is then emitted from one or several elements onto the material to be treated. Such infrared heating elements are in particular: - thermal infrared emitters in the form of tubular, plate-like or otherwise shaped ceramics with a resistive element inside; - infrared quartz glass tube or halogen lamp emitters with a hot filament as a source; - non insulated elements made from molybdenum disilicide, silicon carbide, graphite, ironchromium- aluminium alloys like KanthalTM or comparable materials; - wide-spectrum arc lamps.

Sécurité dans les installations électrothermiques - Partie 12 : Exigences particulières pour les équipements de chauffage par rayonnement infrarouge

La CEI 60519-12:2013 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 au matériau destiné à être chauffé ou traité. 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'ondes 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.

Varnost pri električnih grelnih inštalacijah - 12. del: Posebne zahteve za inštalacije z infrardečim električnim ogrevanjem

Ta del standarda IEC 60519 določa varnostne zahteve za industrijsko električno grelno opremo in inštalacije, v katerih infrardeče sevanje, ki ga ustvarijo infrardeča sevala, občutno presega toplotno konvekcijo ali toplotno prevodnost, kar zadeva prenos toplote v material, ki bo obdelan. 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 60519-1:2010 infrardeče sevanje opredeljuje kot 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. Znatni del emisij, npr. iz toplotnih seval, lahko presega 780 nm ali 3000 nm, zato so v tem standardu 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) – 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 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 molibden disilicida, silicijevega karbida, grafita, železo-kromovo-aluminijeve zlitine, kot je KanthalTM ali primerljivi materiali; – električne sijalke širokega spektra.

INTRODUCTION
The scope of this standard covers very different types and designs of infrared equipment used
for many different purposes by the industry. This standard is intended to cover all industrial
infrared equipment types, with some few exceptions described in Clause 1.
As many different types of electroheating equipment emit infrared radiation of hazardous
levels, the scope of this Part 12 of the IEC 60519 series addresses these infrared radiation
aspects for other parts of the series as well. Especially and with reference to IEC 60519-2:2006
1
[3] it has been agreed in TC 27 that this standard covers all kinds of infrared emission
hazards of industrial electroheating installations.
The discussion of infrared radiation has become quite detailed in this standard, as for the
industry there is not any single useful source available for simple, versatile, easy to use and
cost effective measurement methods.
Provisions of this standard relating to hazards by infrared emission from the equipment as such
and from hot workloads can be used as a complement to IEC 60519-2:2006, since such
aspects are not dealt with in that standard.
This standard provides guidance on the assessment and avoidance of hazards caused by
infrared radiation emitted to accessible locations by hot workloads, electrodes, or other thermal
sources belonging to electroheating equipment.
The other principles for covering the risks caused by infrared radiation were:
– Neither the manufacturer nor the user of electroheating equipment usually employs an
expert in optical radiation measurement or has access to an optical laboratory with all the
necessary equipment needed for elaborate measurements.
– Operating staff with limited experience in radiation measurement is usually responsible for
the task of performing the necessary measurements and will appreciate a simple and easy
to follow guide.
– EN 14255-2:2005 is defined for and useful for lamps only [8].
– EN 12198 series is not very detailed on measurement methods. It gives good guidance on
procedures to improve the safety of equipment. Some material from this source has been
adapted [9 – 11].
– The scope of IEC 62471:2006 is limited to lamps but that standard can be used for other
light sources. Therefore, core aspects were adapted and if possible simplified for this
standard. Content that is essential for safety of electroheating equipment is included in this
standard.
– Figures illustrating the classes defined in IEC 62471:2006 are included to provide a more
understandable and useful standard (IEC 62471:2006 provides data only in the tables).
– Relevant documents of American National Standard Institute / Illuminating Engineering
Society of North America, the ANSI/IESNA RP 27 series [12 – 14], are based on the
ICNIRP recommendations [1, 2] as well. They provide no extra material with regard to this
standard and its references.
A new infrared warning sign shown in Annex GG has been defined in liaison with IEC/SC 3C.

SAFETY IN ELECTROHEATING INSTALLATIONS –

Part 12: Particular requirements for infrared electroheating installations



1 Scope and object
This clause of Part 1 is replaced by the following.
Replacement:
This part of IEC 60519 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 material to be treated. 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.
IEC 60519-1:2010 defines infrared as radiation within the frequency range between about
400 THz and 300 GHz. This corresponds to the wavelength range between 780 nm and 1 mm
in vacuum. Industrial infrared heating usually uses infrared sources with rated temperatures
between 500 °C and 3 000 °C; the emitted radiation from these sources dominates in the
wavelength range between 780 nm and 10 µm.
Since substantial emission of e.g. blackbody thermal emitters may extend beyond 780 nm or
3 000 nm, the safety aspects of emitted visible light and emission at wavelengths longer than
3 000 nm are also considered in this standard.
This standard is not applicable to:
– infrared installations with lasers or light-emitting diodes (LEDs) as main sources – they are
covered by IEC 62471:2006, IEC 60825-1:2007 [4] and IEC/TR 60825-9:1999 [5];
– appliances for use by the general public;
– appliances for laboratory use – they are covered by IEC 61010-1:2010 [6];
– electroheating installations where resistance heated bare wires, tubes or bars are used as
heating elements, and infrared radiation is not a dominant side effect of the intended use,
covered by IEC 60519-2:2006 [3];
– infrared heating equipment with a nominal combined electrical power of the infrared
emitters of less than 250 W;
– handheld infrared equipment.
Industrial infrared electroheating equipment under the scope of this standard typically uses the
Joule effect for the conversion of electric energy into infrared radiation by one or several
sources. Radiation is then emitted from one or several elements onto the material to be
treated. Such infrared heating elements are in particular:
– thermal infrared emitters in the form of tubular, plate-like or otherwise shaped ceramics
with a resistive element inside;
– infrared quartz glass tube or halogen lamp emitters with a hot filament as a source;
– non insulated elements made from molybdenum disilicide, silicon carbide, graphite, iron-
TM
chromium-aluminium alloys like Kanthal or comparable materials;
– wide-spectrum arc lamps.

infrared radiation
optical radiation for which the wavelengths are longer than those for visible radiation
Note 1 to entry: The infrared radiation range between 780 nm and 1 mm is commonly subdivided into:
IR-A  780 nm to 1 400 nm, or for a grey emitter 3 450 °C to 1 800 °C surface temperature;
IR-B  1 400 nm to 3 000 nm, or for a grey emitter 1 800 °C to 690 °C surface temperature;
IR-C  3 000 nm to 1 mm, or for a grey emitter less than 690 °C surface temperature.
The temperature corresponds to a spectrum where maximum intensity is at the wavelength of the limit.
These ranges comply with IEC 62471:2006.
Note 2 to entry: In IEC 60050-841:2004, the following terms are defined:
841-24-04 – shortwave infrared radiation or near infrared radiation (780 nm to 2 µm);
841-24-03 – mediumwave infrared radiation or medium infrared radiation (2 µm to 4 µm);
841-24-02 – longwave infrared radiation or far infrared radiation (4 µm to 1 mm).
These terms are not used in this standard.
