This Standard sets out gravimetric procedures for the determination of gold content in the range from 30 % to 99.5 % in gold and gold bearing alloys with < 2 % nickel, < 0.05 % rhodium, < 0.05 % tungsten, < 1 % platinum and < 3 % palladium. This method is not suitable for alloys containing Iridium.
NOTE 1 Recommended methods of sampling bullion for use with this Standard are provided in Appendix A.
NOTE 2 The presence of the following elements may cause difficulties in obtaining a homogeneous sample: iron, lead, antimony or arsenic.
NOTE 3 A preliminary assay may first be performed to determine the gold, silver and base metal present.
