This test method for the analysis of fine gold is primarily intended to test such material for compliance with compositional specifications. It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory and operated in accordance with Guide E 882.1.1 This test method covers the analysis of refined gold for the following elements having the following chemical composition limits:ElementConcentration Range, ppmCopper17 to 300Iron6 to 150Lead17 to 100Palladium7 to 350Silver17 to 5001.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 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.

This test method is intended to test for compliance with compositional specifications. It is assumed that all who use this method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory.1.1 This test method applies to the determination of carbon in refractory and reactive metals and their alloys in concentrations from 0.004 to 0.100 % (see Note 1).Note 18212;Actual instrument range might vary from manufacturer to manufacturer and according to sample size.1.2 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. Specific precautionary statements are given in Section 8.
