The materials covered that must meet ASTM specifications are uranium metal and uranium oxide. Uranium materials are used as nuclear reactor fuel. For this use, these materials must meet certain criteria for uranium content, uranium-235 enrichment, and impurity content, as described in Specifications C 753 and C 776. The material is assayed for uranium to determine whether the content is as specified. Uranium alloys, refractory uranium materials, and uranium containing scrap and ash are unique uranium materials for which the user must determine the applicability of this practice. In general, these unique uranium materials are dissolved with various acid mixtures or by fusion with various fluxes.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 TitleSectionDissolution of Uranium Metal and Oxide with Nitric Acid8.1Dissolution of Uranium Oxides with Nitric Acid and Residue Treatment8.2Dissolution of Uranium-Aluminum Alloys in Hydrochloric Acid with Residue Treatment8.3Dissolution of Uranium Scrap and Ash by Leaching with Nitric Acid and Treatment of Residue by Carbonate Fusion8.4Dissolution of Refractory Uranium-Containing Material by Carbonate Fusion8.5Dissolution of Uranium-Aluminum Alloys Uranium Scrap and Ash, and RefractoryUranium-Containing Materials by Microwave Treatment8.61.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 7.
La présente partie de l'ISO 21068 spécifie des méthodes permettant de doser l'azote total et l'azote calculés comme le nitrure de silicium, l'oxygène total et les composés libres métalliques et contenant de l'oxyde dans les matières premières et produits réfractaires de carbure de silicium.Elle s'applique uniquement aux matériaux contenant du carbure de silicium qui ne sont pas liés à l'azote.

Determination of GHG direct and indirect emissions based on a mass balance method at each process step for the steel industry. Definition of performance indicators will be included as well as rules for consolidation of processes at site level. The objective is the determination of a methodology to evaluate and compare the emission performance over time or between sites. Field test will be organized to compare mass balance methodology and stack measurements for assessment of direct emissions.
