Résumé :	A new thermodynamic property model is presented for trans-1,3,3,3-tetrafluoropropene (trans-CHFdouble bond; length as m-dashCHCF3, HFO-1234ze(E)) based upon available experimental data. This model is an application of the extended corresponding states principle, which is one approach in property modeling for fluids with limited experimental databases. The model is capable of calculating with reasonable accuracies various properties of HFO-1234ze(E), including the PVT relation, energies, heat capacities, and vapor–liquid equilibrium. The reference fluid of the model is 1,1,1,2-tetrafluoroethane (HFC-134a). Comparisons of calculated values using the model are made with experimental data. Typical uncertainties of calculated properties are 0.2% in the vapor pressure, 0.5% in the liquid density, and 5% in the liquid and vapor isobaric heat capacities. In addition, an ancillary equation is given for the vapor pressure. Thermodynamic property diagrams generated using the model are also provided.
