This standard BS 6075-1:1981 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 method of assay of sodium hydroxide for industrial use. This assay can be expressed conventionally, as percentages by mass of NaOH, in two different ways:
- A total alkalinity (NaOH equiv.);
- B caustic alkalinity (NaOH c.), corresponding to the total alkalinity less the alkalinity due to carbonates.
