The difference between explosion-proof certification and explosion-proof approval certificate
Thread Content
Explosion-proof certification and explosion-proof approval certificate are two concepts that many people tend to confuse. According to the explanation on Baidu Baike, explosion-proof certification is a process aimed at determining whether a device meets the requirements of explosion-proof standards, carrying out type tests and relevant suitability tests, and issuing corresponding certificates of conformity. The certificate can be for Ex equipment or Ex components. Explosion-proof certificate: A document used to verify that the equipment meets the standard requirements, as well as the results of type testing and relevant routine tests. The certificate can be for Ex equipment or Ex components. Obviously, this is a distinction between process and result: the explosion-proof certification is the process, while the explosion-proof certificate is the result. Explosion-proof products can obtain an explosion-proof certification after passing the relevant certification. Currently, China’s explosion-proof certification systems include the explosion-proof certificate system, the explosion-proof 3C certification system, and the coal safety certification system. https://pic1.zhimg.com/80/v2-aafa405216d4ffb2f4704dc805a9c0cc_720w.jpg
