Introduction
The scope of this part is the different types and designs of infrared equipment used by the industry for many different purposes. In addition to some special features described in Chapter 1
Exception, this section applies to all types of industrial infrared equipment.
Because many different types of electric heating equipment emit dangerous levels of infrared radiation, GB/T 5959.1-2019 provides
Based on all general requirements for optical radiation, this section provides specific requirements and practical methods for infrared equipment.
Refer to GB 5959.4-2008 [1], this section contains all types of industrial electric heating equipment not given in GB/T 5959.1-2019
Infrared radiation hazard.
The discussion of infrared radiation in this section is very detailed. As far as the industry is concerned, there is no separate useful resource for simple, general, and user
Convenient and cost-effective measurement method.
Other causes of infrared radiation risk are.
--- Electric heating equipment manufacturers generally do not hire optical radiation measurement experts, nor are they equipped with optical laboratories for accurate measurements;
--- Operators engaged in necessary measurement tasks often have limited experience and can only appreciate simple and easy-to-use guidelines;
--- The scope of GB/T 20145-2006 is limited to luminaires, but the standard can be used for other light sources, so its core content applies, such as
If possible, it can be simplified and used in this section;
--- This section adds a diagram of the classification specified in GB/T 20145-2006 and is included in GB/T 5959.1-2019;
--- Related documents of American National Standards Institute/North American Society of Lighting Engineering, ANSI/IESNARP27 series [6-8], are based on
Recommended by ICNIRP [5]. They do not provide additional material regarding this section and its reference documents.
Safety of electrothermal and electromagnetic treatment devices
Part 12. Special requirements for infrared electric heating devices
1 Scope and purpose
1.1 Scope
This article of GB/T 5959.1-2019 is replaced by the following.
instead.
This part of GB/T 5959 stipulates that infrared radiation usually generated by infrared emitters significantly exceeds thermal convection and heat transfer within the device
Guide, as a heat transfer method, the safety requirements of industrial electric heating equipment and devices that transfer energy to the material being processed. A further limitation of the scope is
The maximum spectral radiation wavelength in air or vacuum is above 780nm, and a wide-band continuous spectrum is emitted by such as thermal radiation or high-voltage arc
Infrared transmitter.
GB/T 5959.1-2019 defines infrared as optical radiation with a frequency range between approximately 400THz and 300GHz. In a vacuum
The corresponding wavelength range in 780nm ~ 10μm. Industrial infrared heating usually uses infrared with a rated temperature of 500 ℃ ~ 3000 ℃
Source, the radiation emitted from these infrared sources is mainly in the wavelength range of 780nm ~ 10μm.
Since the emission wavelength of a large number of thermal emitters may be lower than 780nm or higher than 3000nm, this section also considers the visible
Problems with the safety of light and radiation with wavelengths exceeding 3000 nm.
This section does not apply to.
--- Infrared device with laser or light-emitting diode (LED) as the main radiation source --- GB/T 20145-2006 and
IEC 60825-1..2014 [2] applies to such devices;
--- Utilities appliances;
--- Laboratory electrical appliances --- IEC 61010-1..2010 [3] applies to such appliances;
--- Resistance heating bare wire, electric heating tube or electric heating rod as the heating element, and infrared radiation is not the dominant vice in the expected application
The function of the electric heating device is specified by GB 5959.4-2008 [1];
--- Infrared heating equipment with a nominal total power of less than 250W for all infrared emitters;
--- Handheld infrared device.
Industrial infrared electric heating equipment within the scope of this part usually uses the Joule effect to convert electrical energy into infrared through one or more radiation sources
Radiation, and then radiation from one or more components to the material being processed. The following infrared heating elements are even more so.
--- Tube, plate or other shape ceramic thermal infrared transmitter with resistance element inside;
--- Infrared quartz glass tube or halogen lamp emitter with high temperature filament as radiation source;
--- Non-insulating components made of molybdenum disilicide, silicon carbide, graphite, iron-chromium aluminum alloy, refractory metal or similar materials;
--- Wide spectrum arc lamp.
