Description

1.1 These test methods cover the chemical analysis of chromium and ferrochromium having chemical compositions within the following limits:

1.2 The analytical procedures appear in the following order:

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 %.
