**RC318**

RC318 provides high accuracy thermodynamic and transport properties for RC318 (octafluorocyclobutane, C4F8, MW 200.03 g/gmole) using the Fundamental Equation of State as described by Reiner Tillner-Roth, "Fundamental Equations of State", Shaker, Verlag, Aachan, 1998. The correlation is valid for temperatures in the range between 233.3 K and 623 K for pressures less than 60 MPa. The correlation is based on information from:

Platzer, B., Polt, A., and Maurer, G., "Thermophysical Properties of Refrigerants," Springer-Verlag, Berlin, 1990.

The parameters for the fundamental equation of state and ancillary equations were provided by Professor Steve Penoncello, College of Engineering, University of Idaho, Moscow, Idaho, 83844-1011
