Explosion proof certification and explosion-proof qualification certificate are two concepts that many people easily confuse.
From the explanation on Baidu Baike:
Explosion proof certificationIt is the work of determining whether the equipment meets the requirements of explosion-proof standards, conducting type tests and routine tests for adaptation, and issuing relevant qualification certificates.The certificate can be for Ex devices or Ex components.
Explosion proof certificate: used to determine whether the equipment meets the requirements of standards, type tests, and adaptabilityZhongnuo TestingThe files of routine tests.The certificate can be for Ex devices 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.
Explosion proof products can obtain an explosion-proof certificate after passing the explosion-proof certification.
At present, China's explosion-proof certification mode is divided intoExplosion proof certificateSystem, Explosion proof 3C Certification System, and Coal Safety Certification System.
