This Standard sets out gravimetric procedures for the determination of gold content in the range 0.2% to 30% in gold and gold bearing alloys with, <2% nickel, <0.05% rhodium, <0.05% tungsten and (0.5% tin. Platinum (10% and palladium (3%.Two methods of gold determination are specified: the first method is used when the total precious metal content is less than 40% and the second method is used when the total precious metal content is 40% or greater.A preliminary assay may first be performed to determine the gold, silver and base metal present.The presence of the following elements may cause difficulties in obtaining a homogeneous sample: iron, lead, antimony, nickel or arsenic.
