Scope

This part of GB 3836 specifies the general requirements for the structure, testing, and marking of electrical equipment and Ex components used in explosive environments.
Electrical equipment that complies with the provisions of this part is suitable for use in hazardous areas with explosive environments under the following standard atmospheric conditions, except when a part supplementing this part is modified:
Temperature: -20 °C to +60 °C;
Pressure: 80 kPa to 110 kPa;
Standard oxygen content in the air (by volume): 21%.
Electrical equipment used under atmospheric conditions exceeding this range requires special consideration and may require additional assessments and testing.
Note 1: Although the above-mentioned atmospheric temperature range is -20 °C to +60 °C, the normal temperature range used by the equipment is still -20 °C to +40 °C, unless otherwise specified and marked, see 5.1.1.
Note 2: When designing equipment for use in explosive environments exceeding the above-mentioned atmospheric conditions, this part can be used as a guide. However, it is recommended to conduct additional tests related to the intended use environment. This is particularly important when using explosion-proof enclosures "d" (GB 3836.2—2010) and intrinsically safe types "i" (GB 3836.4—2010 or GB 12476.4—2010).
Note 3: The requirements given in this part are based on the assessment of the ignition hazard posed by electrical equipment. The ignition sources considered are hot surfaces, mechanical sparks, aluminothermic reactions, electric arcs, and electrostatic discharges in general industrial environments.
Note 4: It is well known that with technological development, the explosion-proof objectives of the GB 3836 series standards may be achieved through methods that have not yet been fully determined. If the manufacturer wishes to utilize these technologies, they may partially adopt this part and other standards of the GB 3836 series
