ISO International Standard

Describes a method of subsampling suitable for taking aliquots from a representative sample of uranium hexafluoride in the liquid phase. The subsamples are intended for isotopic analysis (1 g bis 3 g), impurity analysis (10 g bis 200 g) and uranium assay (5 g bis 10 g). Carbon halides, hydrocarbons and certain metal halides can be measured directly from the sample.
