Do we need to do explosion-proof design before applying for explosion-proof certification for products?

This is for sure.

To obtain explosion-proof certification for a product, it is necessary to pass the relevant testing items of explosion-proof standards and obtain an explosion-proof qualification certificate.

If a product wants to pass the relevant testing items of explosion-proof standards, it must be designed according to the testing requirements, which is to do explosion-proof design.

For example, explosion-proof design should refer to GB/T3836.1 and GB/T3836.2, intrinsic safety design should refer to GB/T3836.1 and GB/T3836.4, and positive pressure design should refer to GB/T3836.1 and GB/T3836.5

The national explosion-proof standard GB/T 3836 series has clear design requirements for various explosion-proof types, different explosion-proof areas, different explosive environments, etc.
