Scope

This Document specifies a method for determining the content of precious metals by
determining the content of impurity elements in gold, platinum, and palladium alloy
jewellery.
This Document is applicable to gold alloy jewellery with gold content of 725‰~999‰,
platinum alloy jewellery with platinum content of 800‰~999‰, and palladium alloy
jewellery with palladium content of 800‰~999‰.
NOTE: The applicable measurement range of the precious metal content is the range covered
by the precision test. It may also be applicable beyond this range, but the laboratory is required
to verify the test beyond the range.
