Description of the design and operation of an instrument for the measurement of the viscosity of liquids in the temperature range 10-15 degree C and the pressure range 0. 1-30 MPa. Measurements of the viscosity of liquid water under these conditions are reported. The instrument is of the oscillating-disk type and its design has been carried out with due regard to the theory of its operation and other, physical, constraints so as to optimize the precision of the viscosity measurements for water and aqueous solutions of inorganic salts. The experimental data are compared with the correlation promulgated by the Eighth International Conference on the Properties of Steam. The standard deviation is one of only plus or minus 0. 3%, which is within the eror band of the international correlation. Owing to the high precision of the experimental results, they are to be preferred. A correlation of the present experimental data is provided which reproduces the tabulated viscosities to within their estimated uncertainty.
