Used Formulations
The library uses new industrial formulation for steam tables, called "IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam (IAPWS-IF97)", and replaces the previous industrial formulation for steam tables, IFC-67.

IAPWS-IF97 improves significantly both accuracy and speed of the calculation of the thermodynamic properties compared with the old formulation.

For transport properties calculations are based on the latest internationally accepted equations also available from IAPWS.
