Measurements of PvT properties, saturated densities, and critical parameters were carried out for a low-GWP refrigerant: 3,3,3-trifluoropropene (HFO1243zf, CF3CH═CH2). Seventy-five property data points along seven isochores around the point obtained in temperature range from 328 to 430 K, density between 50 899 kg m–3, at pressures up 6.9 MPa by isochoric method. Fourteen densities observation meniscus disappearance region. On basis these measurements, Tc = 376.93 ± 0.01 K ρc 414 3 m–3 determined. The present results are compared an available equation state.
