1.1 This specification establishes the requirements for high conductivity, tough-pitch, copper wire bars, cakes, slabs, billets, ingots, and ingot bars.


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.


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