ESDU 95019 tabulates the viscosity of twenty-six aliphatic ethers at saturation pressure for temperatures from just above the melting point to approximately 0.9 of the critical temperature. Experimental data extracted from the literature were fitted by an equation for the logarithm of dynamic viscosity as a function of reduced temperature. The equation contains four constants and the values determined for them from the correlation are tabulated for each compound. Viscosities are given at 10 K and 10 degree Celsius intervals@ together with an assessment of the uncertainty in each value. The sources of the data for each compound are listed@ and the critical temperature is given. It is noted that viscosity increases by 1 per cent for a pressure increase of 10 bar@ and an equation is suggested for calculating the effect of pressure up to 500 bar. A full bibliography is given of the sources consulted.
