    Abstract - (Show below) - (Hide below)

    Sets out a gravimetric procedure (fire assay) for the determination of gold content in gold and gold bearing alloys. This method is applicable to gold and gold alloys containing from 30 percent to 99.5 percent gold and less than 3 percent palladium, 2 percent nickel, 1 percent platinum, 0.05 percent rhodium and 0.05 percent tungsten.

    Scope - (Show below) - (Hide below)

    This Standard sets out a gravimetric procedure (fire assay) for the determination of gold content in gold and gold bearing alloys. This method is applicable to gold and gold alloys containing from 30% to 99.5% gold and less than 3% palladium, 2% nickel, 1% platinum, 0.05% rhodium and 0.05% tungsten.NOTES: 1 Recommended methods of sampling dore bullion for use with this Standard are provided in Appendix A.2 The presence of the following elements may cause difficulties in obtaining a homogeneous sample: iron, lead, antimony or arsenic.
