ASTM B5-22 - 1.10.2022
 
Significance and Use

14.1?Calculated values shall be rounded to the specified number of places in accordance with Practice E29.

 
1. 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.

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?UnitsThe 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?ExceptionElectrical 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.
