Tillner-Roth, R. and Baehr, H.D., "An international standard formulation of the thermodynamic

properties of 1,1,1,2-tetrafluoroethane (HFC-134a) for temperatures from 170 K to 455 K at

pressures up to 70 MPa" J. Phys. Chem. Ref. Data, 23:657-729, 1994.
(Typical uncertainties are 0.05% for density, 0.02% for vapor pressure, 0.5-1% for

heat capacity, 0.05% for vapor speed of sound, and 1% for liquid speed of sound, except

in the critical region.)
