The equation received in work considers asymmetry of a real liquid concerning critical isochoruses. The quantitative estimation of its accuracy and the size of working area is spent on an example of the description of equilibrium properties R218. The error of the description of density and isochoric thermal capacities in single-phase area, warmth of steam formation, pressure and density on a line of phase balance the offered not analytical equation of state is comparable with a margin error corresponding experimental data.
