Significance and Use | ||||||||||
5.1 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 C996 and C787 by means of the appropriate test method (for example, Test Method C761 and references therein). The quantities involved, physical properties, chemical reactivity, and hazardous nature of UF6 are such that for representative sampling, specially designated equipment must be used and operated in accordance with the most carefully controlled and stringent procedures. This practice indicates appropriate principles, equipment and procedures currently in use for subsampling of liquid UF6. It is used by UF5.2 It is emphasized that this test guide is not meant to address conventional or nuclear criticality safety issues. |

1. Scope | ||||||||||
1.1 This practice is applicable to subsampling uranium hexafluoride (UF6), using heat liquefaction techniques, from bulk containers, obtained in conformance with C1052, into smaller sample containers, which are required for laboratory analyses. 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 UF1.4 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. |
