Are there any mandatory requirements regarding sampling for re-inspection of steel plates? Such as the sampling location.
Select the appropriate testing standard based on the test items. For materials that comply with national standards, the sampling method for mechanical testing is specified in GB2975; the standards for tensile testing are GB228, those for bending testing are GB232, and those for impact testing are GB229. For materials that meet American standards, the mechanical testing sampling methods and relevant standards include A20, A6, A370, etc.; other standards are not listed here one by one. Wugang Panglong
Generally, re-inspection is the responsibility of the factory itself; it is sufficient to conduct inspections and take samples in accordance with the ordering requirements. If the retesting requirements are higher than those specified in the order, then it is meaningless if the retesting results are unsatisfactory; it is not possible to determine that the material is defective. Check whether the ordering specifications specify the sampling location; the reinspection should not exceed these requirements.
