According to the Standardization Law of the People's Republic of China, all explosion-proof standards are mandatory standards and must be enforced. Explosion-proof products (including imports) used in China must be certified by the state-designated explosion-proof inspection agency. Explosion-proof inspection and certification agencies, in accordance with the Chinese national standard GB3836 series, review and test the explosion-proof performance of explosion-proof motors, explosion-proof electrics, explosion-proof lights, explosion-proof instruments, explosion-proof communication equipment, explosion-proof transportation vehicles and explosion-proof mechanical equipment, and issue explosion-proof certificates. In addition to the GB3836 standard, China's coal safety certification also adopts China's unique industry standards for mining products.

China's explosion-proof standards are basically formulated according to the IEC standards of the International Electrotechnical Commission.

The relevant parameters of the same version of the national standard and the European standard are basically the same, but due to the time lag, the relevant parameters of the national standard are different from the European standard. In the 2004 and 2007 editions of the IEC standard, IIA and IIB have implemented the same parameter requirements.

However, the requirements of China's explosion-proof standards are basically the same as those of IEC. Some of China's GB3836 standards (gas) and GB12476 standards (dust) directly adopt IECEx explosion-proof standards.
