1.1 This practice covers dissolution treatments for uranium materials that are applicable to the test methods used for characterizing these materials for uranium elemental, isotopic, and impurities determinations. Dissolution treatments for the major uranium materials assayed for uranium or analyzed for other components are listed.
1.2 The treatments, in order of presentation, are as follows:
| Procedure Title | Section |
| Dissolution of Uranium Metal and Oxide with Nitric Acid | 8.1 |
| Dissolution of Uranium Oxides with Nitric Acid and Residue | 8.2 |
| Dissolution of Uranium-Aluminum Alloys in Hydrochloric Acid | 8.3 |
| Dissolution of Uranium Scrap and Ash by Leaching with Nitric | 8.4 |
| Dissolution of Refractory Uranium-Containing Material by | 8.5 |
| Dissolution of Uranium—Aluminum Alloys | 8.6 |
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
