ASTM C1508-18

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.
