This standard BS 6075-6:1981 Methods of sampling and test for sodium hydroxide for industrial use is classified in these ICS categories:
- 71.060.40 Bases
This International Standard specifies a titrimetric method for the determination of the carbonates content of sodium hydroxide for industrial use. The method is applicable to products having carbonates contents, expressed as CO2, greater than 0,01 % (m/m):
Three cases, selected by a preliminary test, are envisaged:
1.1 Sodium hydroxide containing neither sulphides nor chlorates.
1.2 Sodium hydroxide containing sulphides.
1.3 Sodium hydroxide containing chlorates.
