Densities of 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1,1,1,3,3,3-hexafluoropropane (HFC-236fa) have been measured for temperatures from 293 to 373 K and pressures up to 70 MPa, with a high-pressure vibrating tube densimeter system in the liquid state. The system was calibrated using water and vacuum via the method of Lagourette et al. The uncertainty in the density measurement was estimated to be +-0.6 kg m-3. The experimental results were correlated to a Tait equation. The average absolute percentage deviations of measurement results from the correlations of HFC-245fa and HFC-236fa are 0.0096% and 0.031%, respectively.
