How about People's Republic of China (PRC) (PRC) special equipment inspection and testing personnel certificate?

You are talking about two kinds of certificates, one is inspection qualification certificate, the other is testing qualification certificate, which is a qualification certificate issued by AQSIQ. The former is valid only if it belongs to the inspection organization, and it is the inspection qualification of corresponding special equipment, such as elevator inspector. The latter must belong to the testing organization to be effective. It is the qualification of the corresponding testing type, such as the second-level certificate of ultrasonic testing in nondestructive testing. The scope of inspection qualification certificate is relatively narrow, and the scope of application of inspection qualification certificate is wider. Now many social inspection and testing institutions have been established in various places, and these certificates may be more popular.
