1 Scope

GB/T 18497.2-2019 is the Chinese national standard on characteristics of electric infrared emitters for industrial heating - part 2: mediumwave and longwave electric infrared emitters, in the field of manufacturing engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 4 June 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2020. Classification: ICS 25.180.10, CCS K61. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This part of GB/T 18497 specifies the type structure, specifications and basic parameters, technical requirements, and tests of medium and long wave electric infrared emitters. Method, inspection rules, marking, packaging, transportation and storage. This section applies to various non-metallic substrates and metal matrix electric infrared emitters with a peak radiation wavelength of not less than 2 µm for industrial heating. (hereinafter referred to as the transmitter). This part refers to the normal full emissivity, spectral emissivity, infrared radiation wavelength range, effective radiant energy ratio, infrared radiation energy density Infrared radiation characteristics such as degree, electro-thermal radiation conversion efficiency, radiation surface temperature unevenness, etc. are also applicable to various infrared radiation functions. Testing and evaluation of materials and appliances. For applications in scientific research, agriculture, health care, building heating, transportation, food, aquaculture, etc., please also refer to this section. use.
