[Current]Copper and copper alloys — Sampling for chemical and spectrochemical analysis, and physical testing
Sets out methods for obtaining a representative sample of copper and copper alloys and procedures for the preparation of laboratory samples required for the determination of their chemical composition by both chemical and spectrochemical analyses. The samples are taken either from molten metal or from cast forms. This Standard is also suitable for sampling copper and copper alloys for selective physical tests.
