ASTM C1865-18 PDF

Scope: 1.1 This test method is for the determination of the carbon and sulfur contents in plutonium oxide (PuO2) powder. The method utilizes an induction furnace purged with oxygen for combustion of the sample. Carbon dioxide and sulfur dioxide produced by the combustion are swept into absorption cells and quantified by infrared absorption spectrophotometers. This test method is an alternative to the methods for carbon and sulfur given in Test Method C697. 1.2 Determination of the carbon and sulfur contents in nuclear-grade sintered mixed oxide (MOX) fuel pellets requires the use of larger samples and is addressed in Test Method C1853. 1.3 The values stated in SI units are to be regarded as standard. Units of measurement in parentheses are included for information only. 1.4 This standard may involve hazardous materials, operations, and equipment. 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.
