Significance and Use
4.1 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:
| Element | Range, % |
| Aluminum | 0.05 to 0.30 |
| Beryllium | 97.5 to 100 |
| Beryllium Oxide | 0.3 to 3 |
| Carbon | 0.05 to 0.30 |
| Copper | 0.005 to 0.10 |
| Chromium | 0.005 to 0.10 |
| Iron | 0.05 to 0.30 |
| Magnesium | 0.02 to 0.15 |
| Nickel | 0.005 to 0.10 |
| Silicon | 0.02 to 0.15 |
1.2 The test methods in this standard are contained in the sections as follows.
|
| Sections |
| Chromium by the Diphenylcarbazide Spectrophotometric Test Method | 10 – 19 |
| Iron by the 1,10-Phenanthroline Spectrophotometric Test Method | 20 – 29 |
| Manganese by the Periodate Spectrophotometric Test Method | 30 – 39 |
| Nickel by the Dimethylglyoxime Spectrophotometric Test Method | 40 – 49 |
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 the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
