Applies to low levels in high purity copper cathode specified in BS 6017.

This Part of BS 7317 describes a method for the determination of the actual amounts of the impurity elements phosphorus and silicon present in high purity copper cathode (designated Cu-CATH-1), by spectrophotometry. It is applicable to concentrations of the elements not exceeding the following limits:

phosphorus 20 µg/g (0.0020 % m/m) maximum;
silicon 25 µg/g (0.0025 % m/m) maximum.

NOTE The titles of the publications referred to in this Part of BS 7317 are listed on the inside back cover.
