1.1This practice is applicable to subsampling uranium hexafluoride (UF₆), using heat liquefaction techniques, from bulk containers, obtained in conformance with Practices C1052, C1703, and C1883, into smaller sample containers, which are required for laboratory analyses.

1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3It is assumed that the liquid UF₆ being sampled comprises a single quality and quantity of material. This practice does not address any special additional arrangement that might be required for taking proportional or composite samples.

1.4The number of samples to be taken, their nominal sample weight, and their disposition shall be agreed upon between the parties.

1.5The scope of this practice does not include provisions for preventing criticality incidents.

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 and health 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.
