CFX 10.0. Make an RGP file or use the Redlich Kwong Equation of State

CFX 11.0. Same as CFX 10.0 or use the IAPWS equation of state.

Hi all!
I have a guestion about iapws-if97 in Ansys Cfx. In my library materials, iapws steam have diferent scope (range) than in The International Association for the Properties of Water and Steam releases.
For egzample: Steam 1 in my CFX have 273.15<T<450 K and 620<p<100 kPa while in IAPWS releases Steam 1 have: 273.15<T<623.15 K and ps(T)<p<100MPa.
If You know why, please answer.

Thanks for attention.
Marcin
