25、N _ 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
26、 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
27、 (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 liaisin
28、g 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,
29、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
30、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 Com
31、mittees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not pro
32、vide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the la
33、test edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, wh
34、ether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
35、indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 6
36、2693 has been prepared by IEC technical committee 27: Industrial electroheating and electromagnetic processing. The text of this standard is based on the following documents: CDV Report on voting 27/877/CDV 27/902/RVC Full information on the voting for the approval of this standard can be found in t
37、he report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 62693 IEC:2013 5 INTRODUCTION This standard on particular test methods for infrared electroheating installations is one of TC 27 standards that describe test methods
38、 for various types of electroheating installations. Test methods for ovens under the scope of IEC 60397 3 1are also covered in this standard when infrared radiation is the intended heat transfer in such equipment this is assumed to be valid above an actual or processing temperature of 700 C, indepen
39、dently of the rated temperature of the oven. This standard is solely concerned with tests for infrared equipment and installations. Tests that focus on the performance of infrared emitters will be covered by IEC 62798 211. The rationale for this separation is that infrared installations are usually
40、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 valuable to manufacturers of infrared installations. The major
41、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, as these are of major interest for manufacturers and users
42、 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 assessment of energy use and for energetic optimisation of instal
43、lations as well. _ 1Numbers in square brackets refer to the Bibliography. 2Under consideration. 6 62693 IEC:2013 INDUSTRIAL ELECTROHEATING INSTALLATIONS TEST METHODS FOR INFRARED ELECTROHEATING INSTALLATIONS 1 Scope and object This International Standard specifies test procedures, conditions and met
44、hods 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 a
45、re 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
46、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 ra
47、ted 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 the conversion of electric energy inside one or several sources into infra
48、red 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
49、 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 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; a
