Scope: 1. This standard specifies the structural requirements, inspection and testing of flameproof electrical equipment used in explosive gas atmospheres. In addition to complying with this standard, the flameproof type must also comply with the relevant provisions of GB 3836.1-2000 "Electrical Equipment for Explosive Gas Atmospheres Part 1: General Requirements". This standard applies to flameproof enclosures and enclosure components made of metallic and non-metallic materials (see Appendix A for supplementary requirements for non-metallic materials). 2. The ambient temperature of explosive gas applicable to this standard is -20℃～+60℃. The ambient temperature of electrical equipment operation is -20℃～+40℃. When the ambient temperature is lower than -20°C, due to the low temperature may produce high explosion pressure and brittle cracking of the shell material, a higher strength shell is required; when the ambient temperature exceeds 60°C, the maximum test safety gap will be caused by the high temperature Reduction requires the use of housings with a smaller gap between the mating surfaces. 3. This standard only deals with the flameproof type but not with other explosion-proof measures to prevent the explosion hazard. Those contents are in the individual standards of the GB 3836 standard.
