Full Description

BS EN ISO 11426:2016 specifies a cupellation method (fire assay) for the determination of gold in gold jewellery alloys. The gold content of the alloys should preferably lie between 333 and 999 parts per thousand (%).

The procedure is applicable 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, as well as for alloys containing 990 or more parts per thousand (%) of gold.

This International Standard is intended to be used as the recommended method for the determination of fineness in alloys covered by ISO 9202.
