The water in a test portion is removed by azeotropic destillation with boiling xylene or petroleum. The volume of the water collected is measured. The method is applicable to products in the form of powders having water contents greater than 5 % (m/m), and in the form of pastes ans solutions. It is not applicable to samples containing water-soluble volatile compounds, for example ethanol.
