适用范围：This International Standard specifies a gas-volumetric method for the determination of the carbonates content, expressed, respectively, as sodium carbonate or potassium carbonate, of sodium and potassium silicates for industrial use. Three cases, defined by a preliminary test, are envisaged : 1 Sodium or potassium silicates containing neither sulphides nor chlorates. 2 Sodium or potassium silicates containing sulphides. 3 Sodium or potassium silicates containing chlorates.
