Equipment used in flammable and explosive places in China must undergo explosion-proof certification and pass the testing requirements of the GB/T3836 series standards before it can be put into use.

Explosion proof certification is a broad concept, which refers to the process of obtaining an explosion-proof certificate for a product. After obtaining explosion-proof certification, one can obtain an explosion-proof qualification certificate.

Explosion proof 3C certification refers to mandatory product certification for products included in the explosion-proof 3C catalog, which only includes a portion of explosion-proof electrical products. Explosion proof electrical products listed in the explosion-proof 3C catalog must undergo explosion-proof 3C certification and obtain CCC certificate. Explosion proof products outside the CCC catalog must obtain an explosion-proof certificate.
