New Test Method for Standard Test Method for Determination of Surface Oxides on Copper Rod (for Electrical Purposes)

1. Scope

The formulation and standardization of specifications, the development of qualifications data and test methods, and the stimulation of research on copper refinery shapes, copper and copper alloy castings, and copper and copper alloy wrought products. The committee participates in joint activity with other committees on related matters of mutual interest.
Refinery shapes include cathodes, cakes, slabs, billets, wire rod and wire bars. Castings include ingots for remelting, deoxidizers, and hardeners for copper and copper-base alloys and sand, centrifugal, die, precision and continuous cast products. Wrought products include fabricated flat products (plate, bar, sheet, strip, foil, and flat wire), rod, wire shapes, forgings, pipe and tubular products, cartridge case and bullet jacket cups.


Uniform Surface Oxides; Subsurface Oxides; Pops Test; Oxide thickness; copper rod


Even though this test is mandatory to comply with B49 specification for Copper Rod for Electrical Purposes, currently there is no ASTM standard describing how the measurement of the oxide layer thickness on the copper rod should be conducted . Recently the method has been tested by several laboratories and a Precision and Bias statement has been issued. The test method will be primarily used by the producers of the copper rod for electrical purposes to measure the thickness of the copper oxide layer on the rod surface, making sure the rod is compliant with the B49 requirements. The method can be also successfully used to evaluate at some extent the amount of copper oxides in the subsurface of a copper rod that has been submitted to a torsion (twist) test.

The title and scope are in draft form and are under development within this ASTM Committee.
