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

Importancia y uso:

5.1 The copper oxides layer present on the surface of the copper rod has a detrimental effect on both final surface quality of the copper wire produced by cold drawing of the rod, and on the drawing process itself leading to wire breaks and excessive wear of the drawing dies. Thus, it is critical to use adequate cleaning techniques during the copper rod manufacturing process in order to limit the depth of the residual copper oxide layer on the finished rod, and it is necessary to have a method to accurately measure the copper oxide depth.

5.2 This test method is the most common test method used by continuous casting and rolling mills to measure the depth of residual surface oxides after the copper rod has been cleaned.

5.3 Applicability of the test method for any other purpose or product has not been evaluated. Suitability beyond the stated scope shall be evaluated before use.
