Withdrawn
Abstract
The method is based on drying a test portion at 105 °C and determination of the loss in mass, which corresponds to the content of water and other components volatile at that temperature. Applies to fluorspars, which may be dried material containing not less than 0,02 % (m/m) of components volatile at 105 °C, or filter cake.
