Popis
BS 7317-7:1990
This standard BS 7317-7:1990 Methods for analysis of high purity copper cathode Cu-CATH-1 is classified in these ICS categories:
- 77.120.30 Copper and copper alloys
This Part of BS 7317 describes a method for the determination of the actual amount of the impurity element lead present in high purity copper cathode (designated Cu-CATH-1), by atomic absorption spectrophotometry. It is applicable to concentrations of lead not exceeding the following limit.
| Lead | 8 µg/g (0.0008 % m/m) maximum |
NOTE. The titles of the publications referred to in this Part of BS 7317 are listed on the inside back cover.
Low levels of lead in copper cathode specified in BS 6017.
