Introduction

The "Test Methods for Electric Heating Devices" specifies the test methods for different types of electric heating devices, and the special test method standards for infrared electric heating devices.

Must be one of them.

This part also includes the test methods for electric furnaces within the scope of IEC 60397 [3], provided that the infrared radiation is predetermined in such equipment

Heat transfer mode, this assumption is valid when the actual or processing temperature is higher than 700 degrees C, it has nothing to do with the rated temperature of the electric furnace.

This part only relates to the test of infrared equipment and devices. The test of the performance of the infrared transmitter is specified in IEC 62798.

Because infrared devices are usually manufactured by other companies rather than the radiator manufacturer. At the same time, the infrared transmitter is very heavy for infrared devices

Want and unique part. In addition, tests that enable the correct comparison of different infrared emitters will be very valuable to the manufacturer of infrared devices.

worth it.

The main guiding principle of this section is to develop the use of conventional test and measurement equipment for most different types of large or small companies.

Ready to be tested.

The tests in this section focus on the performance and efficiency of the device, because they are also most interested in manufacturers and users of such devices. This

These tests are designed to make fair comparisons of devices belonging to specific categories. This section includes some considerations and tests on energy efficiency, so this

These tests can be used to evaluate the performance and energy optimization of the device.

Part 12.Infrared electric heating device

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 degrees C~3000 degrees 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.

---Tube, plate or other shaped ceramic thermal infrared emitters with resistance elements inside;

---Infrared quartz glass tube or halogen lamp transmitter with high temperature filament as heat source;

---Non-insulating components made of molybdenum disilicide, silicon carbide or similar materials;

---Resistive metal heating element made of nickel-based alloy or iron-chromium-aluminum alloy;

---Wide spectrum arc lamp.

This section does not apply to.

---Infrared device with laser or light emitting diode (LED) as the main radiation source (GB/T 20145-2006[9], GB 7247.1-

2012[6] and IEC /T R60825-9.1999[7] apply to such devices);

---Public electrical appliances;

---Electrical appliances for laboratory use (IEC 61010-1.2010[8] applies to such appliances);

---Resistance heating bare wires, electric heating tubes or electric heating rods are used as heating elements, and infrared radiation is not the dominant side in the expected application

The functional electric heating device is regulated by GB 5959.4-2008 [5];

---Infrared heating equipment with a nominal total power of all infrared transmitters less than 250W;

---Handheld infrared device.

The purpose of these tests is to make fair comparisons of the performance of devices of the same type.

The tests related to the safety of the device are specified in GB/T 5959.12-2020.Tests related to the performance of infrared electrothermal transmitters

It is specified in IEC 62798.2014 [11].

Therefore, this section applies to ovens or furnaces with resistance heating elements within its scope.
