samples
Annex B (informative) Information on electrical resistivity
and conductivity relationships
Annex C (informative) Bibliography

Defines the composition and property requirements for cathodes of two copper grades, Cu-CATH-1 (CR001a) and Cu-CATH-2 (CR002A). Covers procedures for sampling cathodes to be used in cases of dispute between the purchaser and supplier. Also provides information on the relationships between electrical resistivity and conductivity of copper.
