A total of 43 measurement data were measured during the experiment which was conducted on a high precision PVTx test apparatus designed by the authors with slight modifications. Uncertainties of temperature was ±10mK and of pressure was ±500Pa. Purity of sample was either 99.95wt% or 99.98wt%. Data resulting from this experiment matched closely with the newest data published internationally. Compared to our proposed equation for calculating vapor pressure of HFC-134a, the RMS deviation of experimental data was only 0.0531%, showing relatively high precision.
