Significance and Use:

These test methods for the chemical analysis of beryllium metal are primarily intended as referee methods to test such materials for compliance with compositional specifications. 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:

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

1.2 The test methods in this standard are contained in the sections indicated below.

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 problems, 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.

10.1 This test method covers the determination of chromium in concentrations from 0.004 % to 0.04 %.

20.1 This test method covers the determination of iron in concentrations from 0.05 % to 0.25 %.

30.1 This test method covers the determination of manganese in beryllium metal in concentrations from 0.008 % to 0.04 %.

40.1 This test method covers the determination of nickel in concentrations from 0.001 % to 0.04 %.
