EN IEC 60519-4:2022

This part of IEC 60519 provides particular safety requirements for arc furnace installations. This
document deals with the significant hazards, hazardous situations or hazardous events relevant
to industrial arc furnace installations, 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 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 arcresistance furnace using alternating current (SAF AC), or direct current (SAF DC).
NOTE 1 In some documents, the terms "smelter" or "electrical reduction furnace" are used.
Furnace installation for unattended operation is not covered by this document.
This document does not provide requirements for type testing.
NOTE 2 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.
EAF DC and SAF DC are classified as zero frequency (0 Hz) equipment types. EAF AC, SAF
AC and LF are classified as mains frequency (50 Hz or 60 Hz) equipment types. Furnaces being
operated at frequencies outside of the above-mentioned equipment types are not covered by
this document.

Industrial electroheating equipment - Test methods for infrared emitters
EN 62798:2014

This International Standard specifies test procedures, conditions and methods according to
which the main parameters and the main operational characteristics of industrial infrared
emitters are established.
A limitation of the scope of this standard 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 [1] 1 defines infrared as optical 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.
Industrial infrared emitters under the scope of this standard typically use the Joule effect for
the conversion of electric energy in one or several sources into infrared radiation, which is
emitted from one or several elements. Such infrared emitters are especially
– 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, iron-chromiumaluminium
alloys or comparable materials;
– wide-spectrum arc lamps.
This standard is not applicable to
– infrared emitters which are lasers or light-emitting diodes (LEDs);
– infrared emitters for use by the general public;
– infrared emitters for laboratory use.
Most of the tests described, especially the destructive tests, are for type testing.
The tests specified in this standard are intended to be used for evaluating or comparing the
performance of emitters belonging to the same category.
Tests related to performance of industrial infrared electroheating installations are specified in
IEC 62693:2013.
Most tests specified in this standard are applicable to wide-spectrum arc lamps, but not all.

Industrial electroheating installations - Test methods for infrared electroheating installations
EN 62693:2013

This International Standard 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. In industrial infrared electroheating installations, infrared radiation is usually generated by infrared emitters and infrared radiation is significantly dominating over heat convection or heat conduction as means of energy transfer to the workload. IEC 60519-1:2010 defines infrared as optical 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. Installations under the scope of this standard typically use the Joule effect for the conversion of electric energy inside one or several sources into infrared radiation emitted onto the workload. Such infrared emitters are especially - 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 or comparable materials; - restive metallic heating elements made e.g. from nickel based alloys or iron-chromiumaluminium alloys; - wide-spectrum arc lamps. 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. The tests are intended to be used to enable a fair comparison of the performance of installations belonging to the same class. Tests related to safety of the installations are defined in IEC 60519-12:2013. Tests related to the performance of infrared electroheating emitters are specified in IEC 62798:- . Therefore, this standard is applicable to ovens and furnaces with resistive heating elements if they fall under the scope of this standard.
