<jats:p>The paper investigates issues related to construction of the equation of state which takes into account the peculiarities of substance behavior in the critical region and which is associated with the scalihg theory of critical phenomena. Construction method of a unified fundamental equation of state (UFEoS) for SFß that satisfies the power laws of scaling theory (ST) and the requirements imposed on the fundamental equations of state of the virial form (FEoS) is considered. UFEoS is based on a new representation of the scaling hypothesis in variables density – temperature and Benedek hypothesis. The authors have developed FEoS for SF<jats:sub>6</jats:sub> in the range of state parameters: in density up to 2000 kg/m<jats:sup>3</jats:sup>, in temperature from 223.555 to 650 K.
