ASTM E1771 C, N, O & Si Testing in Steel by Combustion/Fusion Methods
ASTM E1771-07 is the standard test method for the determination of copper in anode (99.0 to 99.8%) and blister copper (92.0 to 98.0%). It is used as a referee method, to check materials for compliance with composition specifications. This method can also be applied for the electrolytic determination of copper in some copper alloys and scrap.
