Description of BS EN 62798:2014 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-chromium-aluminium 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.
