| Silicon | 0.02 to 0.15 |
1.2 The test methods in this standard are contained in the sections indicated below.
| Sections | |
| Chromium by the Diphenylcarbazide Photometric Test Method [0.004 to 0.04 %] | 10-19 |
| Iron by the 1,10-Phenanthroline Photometric Test Method [0.05 to 0.25 %] | 20-29 |
| Manganese by the Periodate Photometric Test Method [0.08 to 0.04 %] | 30-39 |
| Nickel by the Dimethylglyoxime Photometric Test Method [0.001 to 0.04 %] | 40-49 |
1.3 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.
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.
