The method is designed to show whether or not the tested materials meet the specifications as given in Specifications C 787 and C 788.

1.1 This method covers the determination of bromine (Br) and chlorine (Cl) in uranium hexafluoride (UF₆) and uranyl nitrate solution. The method as written covers the determination of bromine in UF₆ over the concentration range of 0.2 to 8 μg/g, uranium basis. The chlorine in UF₆ can be determined over the range of 4 to 160 μg/g, uranium basis. Higher concentrations may be covered by appropriate dilutions. The detection limit for Br is 0.2 μg/g uranium basis and for Cl is 4 μg/g uranium basis.

1.2 This standard may involve hazardous materials, operations and equipment. 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.
