These test methods are intended for the determination of the gold content of gold and silver bullion. It is assumed that all who use these test methods are trained assayers capable of performing common fire assay procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.1.1 These test methods cover cupellation analysis of bullion having chemical compositions within the following limits: Element Concentration Range, % Gold 0.5 to 4.0 and 20.0 to 99.8 Silver 1.0 to 99.5 Total gold plus silver75.0 to 100.0 1.2 These test methods appear in the following order: Sections 20.0 % – 99.0 % gold10-17 0.5 % – 4.0 % gold18-23 98.9 % – 99.8 % gold24-30 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific safety hazards, see Section 8. 10.1 This test method covers cupellation analysis of gold in bullion containing 20.0 % to 99.0 % gold and 1.0 % to 80.0 % silver. 18.1 This test method covers the determination of gold in bullion estimated to contain from 0.5 % to 4.0 % gold and 75.0 % to 99.5 % silver. 24.1 This test method covers the cupellation analysis of gold in grade 99.5 refined gold.
