1.1These test methods cover cupellation analysis of bullion having chemical compositions within the following limits:

Element	Mass Fraction Range, %

Gold	0.5 to 4.0 and 20.0 to 99.8
Silver	1.0 to 99.5
Total gold plus silver	75.0 to 100.0

1.2These test methods appear in the following order:

		Sections

Test Method A	20.0 % – 99.0 % gold	10 – 16
Test Method B	0.5 % – 4.0 % gold	17 – 21
Test Method C	98.9 % – 99.8 % gold	22 – 28

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
