Equation of state

The uncertainties of the equation of state are generally 0.1% in density and 2% in the speed of sound, except in the critical region and high pressures.

Estimated uncertainty 0.6% in the dilute gas from room T to 630 K, 2% for the liquid at pressures up to 30 MPa between 273 and 343 K, 3% for pressures from 30 MPa to 100 MPa, 5% for the liquid from 100 to 500 MPa, 10% for 500 MPa to 800 MPa.

Thermal conductivity

Estimated uncertainty in thermal conductivity is 4.4% except near critical where the uncertainties are larger.
