Scope

This part of GB/T 10066 specifies the test procedures, conditions, and methods for industrial infrared electric heating devices, based on which their main parameters and main operating characteristics are determined.
The scope of this part is limited to: infrared emitters that emit a continuous broad-band spectrum through thermal radiation or high-pressure arcs, with a maximum spectral radiation wavelength of more than 780 nm in air or vacuum.
In industrial infrared electric heating devices, infrared radiation is typically generated by infrared emitters, and infrared radiation clearly exceeds thermal convection and thermal conduction as a heat transfer method, transferring energy to the workpiece.
GB/T 5959.1—2019 defines infrared as optical radiation with a frequency range of approximately 400 THz to 300 GHz. In a vacuum, the corresponding wavelength range is 780 nm to 1 mm. Industrial infrared heating typically uses infrared sources with a rated temperature of 500 °C to 3,000 °C, and the radiation emitted from these infrared sources is mainly in the wavelength range of 780 nm to 10 μm.
The devices within the scope of this part typically utilize the Joule effect to convert electrical energy into infrared radiation and emit it to the workpiece from one or more infrared sources. The following infrared emitters are particularly notable:
——Ceramic thermal infrared emitters with resistive elements in a tubular, plate-like, or other shape;
——Infrared quartz glass tubes or halogen lamp emitters with high-temperature filaments as the heat source;
——Non-insulating elements made of molybdenum disulfide, silicon carbide, or similar materials;
——Resistive metal heating elements made of nickel-based alloys or iron-chromium-aluminum alloys;
——Wide-spectrum arc lamps.
This part does not apply to:
——Infrared devices with lasers or light-emitting diodes (LEDs) as the main radiation source (GB/T 20145-2006[9], GB 7247
