Based on International Critical Tables. Density in kg/m³ aqueous solution, mass in g of H₂SO₄ in 100 g of aqueous solution, mass in g of H₂SO₄ in 1 litre of aqueous solution. Notes on standard hydrometers including corrections to be applied and worked examples.

This British Standard gives a table that enables the composition of an aqueous solution of sulphuric acid to be determined from its density at temperatures between 10 °C and 40 °C.

Appendix A gives information on the corrections which are necessary when density is determined by a hydrometer complying with BS 718¹⁾.

Appendix B gives information on the choice of BS hydrometers that are suitable for the determination of density of sulphuric acid solutions.

Appendix C gives examples of the use of a BS hydrometer in conjunction with Table 1.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
