P-V-T equation of state of copper up to high temperature and pressure studied by statistical moment method (SMM). We calculate the P-V-T equation of state for copper of the simple form, without adjustment parameters. The numerical results of the pressure as a function of the compressibility on the copper isotherms, are in good agreement with the values obtained by the previous semiempirical equation of state for copper, at pressure up to 500kbar and temperature up to 2000K. In addition, the expressions for the thermodynamic quantities of copper as simple functions of temperature and pressure are also obtained directly from this equation of state. The numerical results of the thermal expansion coefficient, heat capacity of copper, are in excellent agreement with the experimental data. The P-V-T equation of state of copper obtained in this work can be used as a pressure scale up to 500kbar and temperature up to 2000K.
