Summary

Transport properties (viscosity and thermal conductivity) and surface tension have been measured for the R23-R116 azeotropic mixture (46-54 mass%). Viscosity was measured by capillary tube method, thermal conductivity was measured using the steady state hot wire method, and surface tension was measured by differential capillary rise method. Saturated transport properties and surface tension were determined over a temperature range from -100 to 10 deg C. Transport properties for the vapours at atmospheric pressure were measured over a temperature range from -80 to 100 deg C. Calculated uncertainties of the experimental viscosity, thermal conductivity, and surface tension data are less than more or less 1.2%, more or less 1%, and more or less 0.05 milliN-meter, respectively. A set of equations for viscosity, thermal conductivity, and surface tension are presented.
