A DETERMINATION of the absolute viscosity of water at 20°C with greater accuracy than ever before realized has recently been completed by J. F. Swindells of the National Bureau of Standards, U.S.A. The new value is 0.01002 poise (dyne‐seconds per square cm) as compared with 0.01005 poise which has been generally accepted up to the present time. The absolute viscosity of water serves almost universally as the standard to which the viscosities of all other liquids are referred. Beginning July 1, 1952, the Bureau will use the new value as the primary standard for calibrating viscometers and for evaluating secondary standards which are issued as viscometer calibrating liquids.
