ASTM B5-22 PDF

Scope: 1.1 This specification establishes the requirements for high conductivity, tough-pitch, copper wire bars, cakes, slabs, billets, ingots, and ingot bars. 1.2 Copper under this specification corresponds to the designations “ETP” (UNS C11000) and “FRHC” (UNS C11020) as shown in Classification B224. These coppers may also be used to produce coppers corresponding to the following: Copper UNS No. Classification B224 Designation C11300, C11400, C11500, and C11600 STP C12000 DLP C12200 DHP C12300 DHPS C14520 DPTE 1.3 Although this specification includes certain UNS designations as described in Practice E527, these designations are for cross reference only and are not specification requirements. Therefore, in case of conflict, this ASTM specification shall govern. 1.4 Units—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. 1.4.1 Exception—Electrical resistivity is expressed in SI units. 1.5 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.
