Anotace textu normy 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.
Keywords:
acceptable quality level (AQL), average outgoing quality (AOQ), control chart, lot, lower specification limit (LSL), process average, process control ratio (CPK), skip-lot inspection, statistical process control (SPC), upper specification limit (USL),, ICS Number Code 19.020 (Test conditions and procedures in general)

1.1 This specification covers a standard basis for uniform testing and frequency to determine physical and electrical compliance for aluminum and copper drawing stock, and aluminum and copper conductors. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.2.1 Exception—Resistivity is measured in SI units. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
