1.1The thermophysical property tables for propane are used in calculating the pressure-volume-temperature (PVT), thermodynamic, and transport properties of propane for process design and operations. Two tables provide properties at the conditions of liquid-vapor equilibrium (saturation properties), one for liquid and one for vapor, at temperatures between 90K and the critical point, 380K. A third table provides properties at selected T, p points for the equilibrium phase at temperatures between 90K and 600K at pressures to 20 MPa. The tables were developed by the National Institute of Standards and Technology from a Standard Reference Database product REFPROP, version 9.0.

1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
