Fluid Phase Equilibria, 244 (2006) 193-211

The correlation is valid for temperatures in the range between 214.15 K and 673K for pressures less than 30 MPa.

Values of specific enthalpy and entropy are referred to 0 for saturated liquid at the normal boiling point 482.4 K).

Transport properties are not implemented for this fluid.
