Defines the compositions of copper-based master alloys for the manufacture, deoxidation or desulfurization of cast or wrought alloys, particularly those based on copper ingots, notched bar, notched slab, granules or broken pieces. Contains method for sampling the master alloys for analysing for verifying the conformity to the composition requirements.

This European Standard specifies the compositions of copper-based master alloys intended for the manufacture, deoxidation, or desulfurization of cast or wrought alloys, especially those based on copper, supplied in the form of ingots, notched bar, notched slab (waffle plate), granules or broken pieces. A procedure is included for sampling the master alloys for analysis for verification of conformity to the composition requirements. A method for the determination of chromium(III)-oxide in chromium-copper master alloy is given in annex A.
