The reference state h=200 kJ/kg and s=1.0 kJ/kg-K at 273.15 K for saturated liquid.

The properties are valid for temperatures between 273 K and 430 K for pressures up to 6 MPa.

Viscosity and thermal conductivity have been estimated using a corresponding states approach as suggested in:

Klein, S.A., McLinden, M.O., and Laesecke , A., "An improved extended corresponding states method for estimation of viscosity of pure refrigerants and mixtures", Int. J. of Refrigeration, 20, pp. 208-217, 1997

McLinden et al., "An extended corresponding states model for the thermal conductivity of refrigerants and refrigerant mixtures",

Int. J. of Refrigeration, 23, pp. 43-63, 2000

R236fa was used as the reference fluid. The estimated transport properties should be applicable for the range in which the equation of state is valid.

Surface tension data are provided with a correlation from Chieko Kondou, et al., International Journal of Refrigeration, Vol. 53, (2015) pp. 80-89.
