Full Description

1.1This practice is applicable to sampling gaseous uranium hexafluoride (UF₆) from processing facilities, isotope enrichment cascades or storage cylinders, using the sorbent properties of aluminum oxide (Al₂O₃).

1.2It is based on the ABACC-Cristallini Method (1, 2)2 and is intended to be used for the determination of uranium (U) isotopic composition required for nuclear material safeguards as well as other applications.

1.3The application of this practice assures the resulting sample vessel contains no UF₆ and hydrogen fluoride (HF); therefore, it may be handled and categorized for transport under less stringent constraints.

1.4The scope of this practice does not include provisions for preventing criticality.

1.5Units-The values stated in SI units are to be regarded as the standard. When non-SI units are provided, they are for information only.

1.6This 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.

1.7This 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.
