Measurements of the viscosity of liquid 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) are reported over the temperature range 263.15 K to 343.15 K along the saturation line made with a calibrated capillary viscometer. An improved method was developed for calibrating the viscometer and measuring the viscosity. The uncertainty of the results is estimated to be no more than {+-}3%. The results were correlated as a function of temperature.
