Tests that focus on the performance of infrared emitters will be covered by IEC 62798 211. The rationale for th

28、is separation is that infrared installations are usually manufactured by other companies than infrared emitters. Still, infrared emitters are a very important and distinct part of infrared installations and a set of tests that allow for proper comparison of different infrared emitters will be valuab

29、le to manufacturers of infrared installations. The major guiding principle in this standard is to define tests that can be performed with the usual test and measuring equipment available to most kinds of companies, large or small. The tests focus on the performance and efficiency of installations, a

30、s these are of major interest for manufacturers and users of such installations. The tests are intended to enable a fair comparison of installations belonging to a given class. The standard includes considerations and tests concerned with energy efficiency, so that the tests can be used for assessme

31、nt of energy use and for energetic optimisation of installations as well. _ 1Numbers in square brackets refer to the Bibliography. 2Under consideration. BS EN 62693:2013 6 62693 IEC:2013 INDUSTRIAL ELECTROHEATING INSTALLATIONS TEST METHODS FOR INFRARED ELECTROHEATING INSTALLATIONS 1 Scope and object

32、 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 s

33、pectral 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 radiati

34、on 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

35、 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 m. Installations under the scope of this standard typically use the Joule effect for

36、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 tu

37、be 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-chromium-aluminium alloys; wide-spectrum arc lamps. This standard

38、 is not applicable to infrared installations with lasers or light-emitting diodes (LEDs) as main sources they are covered by IEC 62471:2006 9, IEC 60825-1:2007 6 and IEC/TR 60825-9:1999 7; appliances for use by the general public; appliances for laboratory use they are covered by IEC 61010-1:2010 8;

39、 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 5; infrared heating equipment with a nominal combined electrical power of the infrared e

40、mitters 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. BS EN 62693:201362693 IEC:2013 7 Tests related to safety of the installations are defined in IEC 60519-12:2013. Test

41、s related to the performance of infrared electroheating emitters are specified in IEC 62798: 11. Therefore, this standard is applicable to ovens and furnaces with resistive heating elements if they fall under the scope of this standard. 2 Normative references The following documents, in whole or in
