#EOS               !equation of state specification
FEQ  Helmholtz equation of state for argon of Tegeler et al. (1999).
?LITERATURE REFERENCE \
?Tegeler, Ch., Span, R., and Wagner, W.,
? "A New Equation of State for Argon Covering the Fluid Region for
? Temperatures from the Melting Line to 700 K at Pressures up to 1000 MPa,"
? J. Phys. Chem. Ref. Data, 28(3):779-850, 1999.
?\
?The estimated uncertainty in density is less than 0.02% for pressures up
?to 12 MPa and temperatures up to 340 K with the exception of the
?critical region and less than 0.03% for pressures up to 30 MPa and
?temperatures between 235 and 520 K. Elsewhere, the uncertainty in
?density is generally within 0.2%.  In the region with densities up to
?half the critical density and for temperatures between 90 and 450 K, the
?estimated uncertainty of calculated speeds of sound is in general less
?than 0.02%.  In the liquid and supercritical regions, the uncertainty is
?less than 1%.  The uncertainty in heat capacities is within 0.3% for the
?vapor and 2% for the liquid.  The formulation gives reasonable
?extrapolation behavior up to very high pressures (50 GPa) and
?temperatures (17000 K).
