Now if we use ASME or ASTM105, it is a foreign standard that needs to be re-examined. If we use GB/T12228 directly to submit the material substitution list, is it possible to do so, and then the re-examination is not necessary?
Re-inspection requirements should be stipulated in your product specifications. Generally, it is not necessary to re-inspect the original quality certificates provided. See how your specifications are written.
