AS 2849-1986

Specifies two methods for the determination of the numerical value of the density of water under specified conditions, viz. by reference to a table and by calculation. The value of the density of standard mean ocean water under specified conditions is included in an appendix. The values are those proclaimed in a determination by the National Standards Commission - Recognised-value Standard of Measurement of Density - Water, dated 21 March 1985, in accordance with the National Measurement Act 1960.

This standard sets out two ways of ascertaining the numerical value of the density of water where-(a) the impurities in the water do not exceed ten parts in one million, by mass (see Note 2); (b) the temperature is not less than 0°C nor greater than 40°C; and (c) the pressure is not less than 20 kPa nor greater than 1 MPa.NOTES:1. The value of the density of water is proclaimed in a Determination by the National Standards Commission-Recognised-value Standard of Measurement of Density-Water, dated 21 March 1985, in accordance with the National Measurement Act 1960.2. The density of standard mean ocean water is given in Appendix A.
