ASTM E37-05

These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use these methods 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.

1.1 These test methods cover the chemical analysis of pig lead having chemical compositions within the following limits:

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

1.3 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in the individual test methods.

1.4 This test method covers the determination of bismuth in concentrations from 0.002 to 0.2 %, copper from 0.001 to 0.1 %, silver from 0.001 to 0.03 %, and zinc from 0.001 to 0.005 %.

1.5 This test method covers the determination of antimony in pig lead in concentrations from 0.0008 to 0.005 %.
