Die Annotation des Normtextes ASTM B830-18 :

This specification covers a standard basis for uniform testing and frequency to determine physical and electrical compliance for aluminum and copper conductors. Diameter, tensile, resistivity and all other material properties shall be tested per specific level and acceptable quality level (AQL) and must meet the corresponding requirements. Any lot of drawing stock/wire that has been sampled and from which the number of specimens failing to comply with the requirements does not equal or exceed the appropriate reject number of the sampling used, shall be considered as complying with requirements of ASTM. Rejected lots may be screened to remove nonconforming production units by testing one specimen form each production unit in the lot for the failing characteristic. Identify and classify product, process, and service characteristics for which statistical techniques will be used as basis for the assurance and control of quality and acceptance or rejection of lots. The process performance index (CPK) shall meet the requirements of the applicable ASTM standard.
