Significance and Use

These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications such as Specification A101 and A481. It is assumed that all who use these test 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.

Scope

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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 6.

10.1 This test method covers the determination of arsenic in chromium and ferrochromium in concentrations from 0.001 % to 0.005 %.

21.1 This test method covers the determination of lead in chromium and ferrochromium in concentrations from 0.001 % to 0.05 %.

32.1 This test method covers the determination of chromium in all carbon grades of ferrochromium in concentrations from 50 % to 75 %.
