適用范圍：The document 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 999 parts per thousand 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 socalled white gold alloys, as well for alloys containing 990 or more parts per thousand of gold.
