GB/T 11840-2025 "Method for Determination of Moisture Content in Uranium Dioxide Powder and Pellets" specifies the method for determining the moisture content in uranium dioxide powder and sintered pellets used in the nuclear fuel field. The principle involves using thermogravimetric analysis, where the sample is heated to a specific high temperature in an inert atmosphere or air, and the moisture content is determined by accurately measuring the mass loss before and after heating.
