Active Standard ASTM C1689 | Developed by Subcommittee: C26.05
Book of Standards Volume: 12.01
Historical (view previous versions of standard)
Significance and Use
Uranium hexafluoride is normally produced and handled in large (typically 1- to 14-ton) quantities and must, therefore be characterized by reference to representative samples. The samples are used to determine compliance with the applicable commercial Specifications C 996
It is emphasized that this test guide is not meant to address conventional or nuclear criticality safety issues.
1.1 This practice is applicable to subsampling uranium hexafluoride (UF6), using heat liquefaction techniques, from bulk containers, obtained in conformance with C 1052
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 It 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.
1.4 The number of samples to be taken, their nominal sample weight, and their disposition shall be agreed upon between the parties.
1.5 The scope of this practice does not include provisions for preventing criticality incidents.
1.6 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.
