Explosion proof certification and explosion-proof qualification certificate are two concepts that are easily confused by many people.

From the explanation on Baidu Baike:

Explosion proof certificationIt is used to determine whether the equipment meets the requirements of explosion-proof standards, type tests, and routine tests for adaptation, and to issue relevant qualification certificates.The certificate can be specific to Ex equipment or Ex components.

Explosion proof certificate: used to determine whether the equipment meets the requirements of the standard, type testing, and adaptationZhongnuo TestingThe document for routine testing.The certificate can be specific to Ex equipment or Ex components.

It is obvious that this is the distinction between process and result, explosion-proof certification is the process, and explosion-proof qualification certificate is the result.

After passing the explosion-proof certification, explosion-proof products can obtain an explosion-proof certificate.

At present, China's explosion-proof certification mode is divided intoExplosion proof certificateSystem, explosion-proof 3C certification system, and coal safety certification system.
