ASTM C1636-22 - Standard Guide for Determination of Uranium-232 in Uranium Hexafluoride

1.1 This guide covers the determination of ²³²U in uranium hexafluoride by alpha spectrometry.

1.2 The values stated in SI units are to be regarded as standard, except where the non-SI unit of molar, M, is used for the concentration of chemicals and reagents. The unit of electronvolt (eV) is outside the SI but its use with the SI is accepted by the International Committee for Weights and Measures (CIPM, Comité International des Poids et Mesures) and the U. S. National Institute of Science and Technology (NIST). No other units of measurement are included in this standard.

1.3 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.

1.4 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.
