The correlation is valid for temperatures in the range between 130 K and  440 K for pressures less than 20 MPa.  Enthalpy and entropy values are referenced to 200 kJ/kg and 1 kJ/kg-K respectively for saturated liquid at 273.15 K. 


Transport property data were obtained by curve fitting data from REFPROP 8.
