1 Scope

This part of GB/T 10066 specifies the test procedures, conditions and methods of industrial infrared electric heating devices, and it is determined based on these contents.

Our main parameters and main working characteristics.

The scope of this part is limited to. in air or vacuum, the maximum spectral radiation wavelength is above 780nm, and through thermal radiation or high pressure

Arc and other infrared emitters that emit a wide-band continuous spectrum.

In industrial infrared electric heating devices, infrared radiation is usually generated by infrared emitters, and infrared radiation significantly exceeds thermal convection and heat.

Conduction, as a heat transfer method, transfers energy to the workpiece.

GB/T 5959.1-2019 defines infrared as optical radiation with a frequency range of approximately 400THz to 300GHz. In vacuum

The corresponding wavelength range in 780nm~1mm. Industrial infrared heating usually uses infrared sources with a rated temperature of 500°C~3000°C.

The radiation emitted from these infrared sources is mainly located in the wavelength range of 780nm~10µm.

Devices within the scope of this part typically use the Joule effect to convert the electrical energy in one or more infrared sources into infrared radiation.

Launch to the workpiece. The following infrared emitters are particularly special.
