DESCRIPTION
BS 6092-4:1981
This standard BS 6092-4:1981 Methods of sampling and test for sodium and potassium silicates for industrial use is classified in these ICS categories:
- 71.060.50 Salts
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:
1.1 Sodium or potassium silicates containing neither sulphides nor chlorates.
1.2 Sodium or potassium silicates containing sulphides.
1.3 Sodium or potassium silicates containing chlorates.
