Significance and Use

5.1 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 E882.

1. Scope

1.1 This test method covers the analysis of refined gold for the following elements having the following chemical composition limits:

Element

Content Range, µg/g

Copper

17 to 300

Iron

6 to 150

Lead

17 to 100

Palladium

7 to 350

Silver

17 to 500

1.2 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.
