- Scope
- This recommended practice applies to the regional classification of temporarily or permanently installed electrical equipment, that is, it applies to hazardous areas where flammable gases and vapors mixed with air exist in normal atmospheric environments. Normal atmospheric conditions are when the reference point atmospheric pressure is 101.3kPa (14.7psia) and the temperature is about 20°C (68^(°)F). If the upper and lower changes have a negligible impact on the explosiveness of flammable materials. The following are not included in this recommended practice: a) Flavored natural gas fuel line systems used for cooking, heating, air conditioning, washing machines, and similar equipment. b) Disasters such as blowouts and container bursts. When such extreme situations occur, emergency measures need to be taken. c) The rationality of the installation location of non-electrical equipment. d) Division of areas containing combustible dust, ignitable fibers or flying objects.
