BS 6075-6:1981

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.
