32、t 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 a
33、ddresses these infrared radiation aspects for other parts of the series as well. Especially and with reference to IEC 60519-2:2006 31it has been agreed in TC 27 that this standard covers all kinds of infrared emission hazards of industrial electroheating installations. The discussion of infrared rad
34、iation 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 h
35、ot 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
36、 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
37、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 fo
38、r 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 so
39、urces. 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
40、 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 re
41、gard to this standard and its references. A new infrared warning sign shown in Annex GG has been defined in liaison with IEC/SC 3C. 1Numbers in square brackets refer to the Bibliography. BS EN 60519-12:201360519-12 IEC:2013 7 SAFETY IN ELECTROHEATING INSTALLATIONS Part 12: Particular requirements fo
42、r 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 emitte
43、rs, 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 wid
44、eband 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 us
45、es 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. Since substantial emission of e.g. blackbody thermal emitters may extend beyond 780 nm or 3 000 nm, the safety aspects of emitted
46、 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
47、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, co
48、vered 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
49、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
