Scope

This International Standard specifies a cupellation method (fire assay) for the determination of gold in gold jewellery alloys. Preferably the gold content of the alloys lies between 333 and 930 parts by mass per thousand (%o) of gold. The procedure applies specifically to gold alloys incorporating silver, copper and zinc. Some modifications are indicated where nickel and/or palladium are present in the so-called white gold alloys.
