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.
