Scope

This part of GB 3836 specifies the general requirements for the construction, testing and marking of electrical equipment and Ex components for explosive atmospheres. Electrical equipment complying with the provisions of this Part is suitable for use in hazardous locations where explosive atmospheres exist under the following standard atmospheric conditions, except when a part of this Part is amended as a supplement: Temperature: -20℃～+60℃; Pressure: 80kPa～ 110kPa; standard oxygen content in air (volume ratio): 21%. Electrical equipment used in atmospheric conditions outside this range requires special consideration and may require additional evaluation and testing. Except for those directly related to the explosion hazard, this section does not specify other safety requirements. Ignition sources not covered by this standard are: adiabatic compression, shock waves, exothermic chemical reactions, spontaneous combustion of dust, open flames, and hot gases/liquids.
