This specification covers structural quality carbon steel plates in standard and non-standard grades furnished to chemical composition requirements. The materials shall conform to carbon, manganese, phosphorus, sulfur, silicon, and copper contents of its specified grade. Values are also given to specify the range, limit, and maximum chemical compositions of the carbon steel.1.1 This specification covers structural quality carbon steel plates furnished to chemical composition requirements.1.2 The plates are available in several standard steel grades and non-standard grades.1.3 The plates are usually furnished in the as-rolled (hot-rolled) condition.1.4 Supplementary requirements are provided for additional requirements that may be specified on the order.1.5 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.7 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.

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.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.
