• An equation of state for sulfur hexafluoride (SF_6) is proposed based on the available experimental data. Method and procedures for formulating the equation of state are reported. The proposed equation of state as a function of temperature and density is valid in the range of temperatures from the triple point of 222.35 K to 500 K and of pressures from the ideal gas state to 50 MPa which corresponds to the density variation from 0 to 2000 kg/m^3. The thermodynamic properties calculated by the proposed equation agree well with the available experimental data, which verifies the thermodynamic consistency of the proposed equation. According to the method applied here, it is possible to formulate an equation of state for fluids describing the most reliable thermodynamic state surface.
