ASTM B5

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 B 224. These coppers may also be used to produce coppers corresponding to the following:

1.3 Although this specification includes certain UNS designations as described in Practice E 527, 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 the standard, except for electrical resistivity, which is expressed in SI units. The values given in parentheses are mathematical conversions to SI units, which are provided for information only, and are not considered the standard.
