scope:

This International Standard specifies a method of sampling precious metal jewellery alloys for the
determination of the precious metal content. It is applicable to raw materials, semi-finished products, and
finished products of the jewellery alloys of precious metals. Its aim is to define all the operations needed to
obtain samples intended for the determination of the precious metal content of a particular jewellery alloy. It is
intended to be applied when sampling alloys are claimed to be homogeneous.
Alloys of precious metals used in industrial products, coins qualified as legal tender, dentistry or decorative
coatings on some other material are outside the scope of this standard. It is not intended to apply to
procedures employed for the purposes of production control nor for the provision of samples other than for the
determination of the precious metal content.
