Причина отменыThis test method described the electrolytic determination of copper in commercial anode (99.0 to 99.8%) and blister copper (92.0 to 98.0 %).

Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, this test method was withdrawn in January 2016 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

This test method for the determination of copper in anode (99.0 to 99.8 %) and blister copper (92.0 to 98.0 %) is primarily intended as a referee method, to test such materials for compliance with compositional specifications. It is assumed that users of this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.

This test method is intended to determine the copper content of commercial anode and blister copper. Those elements that interfere are removed by precipitation or volatilization, or both. Copper is electrodeposited as the metal and weighed.

This method will also be found useful for the electrolytic determination of copper in some copper alloys and scrap.
