In this paper, some thermophysical properties at low pressure of sulphur hexafluoride (SF$_6$) fluid are modelled and predicted. Also, by comparing the obtained results with experimental data, the correlation performance of virial coefficients to predict thermodynamic properties over a wide temperature range is evaluated. Studied properties consist of Joule–Thomson coefficient, enthalpy, deviation function, fugacity coefficient, thermal expansion, Boyle temperature and Boyle volume. The studied correlation function is the one suggested by Zarkova et al and compared with correlation of Meng et al. The obtained results show that the correlation equation presented has a good ability to predict the thermophysical properties of sulpur hexafluoride and its deviation from the idealstate over a wide range of temperatures. Average absolute deviations (AAD) of thermophysical properties of SF$_6$ calculated by this approach is mainly below 5%.
