Standard Specification for High Conductivity Tough-Pitch Copper Refinery Shapes

ABSTRACT
This specification establishes the requirements for high conductivity, tough-pitch, copper wire bars, cakes, slabs, billets, ingots, and ingot bars. Copper wires under this specification include UNS C113000, C11400, C11500 and C11600, C12000, C12200, C12300, and C14500. The maximum values of mass resistivity for wire bars, cakes, slabs, and billets, for electrical use and for other uses, shall conform to the specified requirements. Samples for the electrical resistivity test of electrolytic copper, electrorefined copper, electrowon copper, and fire-refined copper shall be fabricated into a rod. The external oxide shall be removed, the rod cold drawn into a wire of a specific diameter, and cut into sampling lengths. The resulting specimen shall be annealed and quickly cooled in an inert atmosphere. The mean resistivity shall be determined as the mean of the observations from the test on the wires.
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 B 224. These coppers may also be used to produce coppers corresponding to the following:Copper UNS No.Classification B 224 DesignationC11300, C11400, C11500, and C11600STP C12000 DLPC12200 DHPC12300 DHPSC14500 DPTE
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.
