This Part of BS 7317 describes a method for the determination of the actual amount of the impurity element sulphur present in high purity copper cathode (designated Cu-CATH-1), by hydrogen sulphide evolution and spectrophotometry. It is applicable to concentrations of sulphur within the range 5 µg/g to 30 µg/g (0.0005 % m/m to 0.0030 % m/m).
