NIST Thermophysical Properties of Hydrocarbon Mixtures Database- SRD 4

Data provided by  National Institute of Standards and Technology

SUPERTRAPP is an interactive computer program for predicting thermodynamic and transport properties of pure fluids and fluid mixtures containing up to 20 components. The components are selected from a database of 210 components, mostly hydrocarbons. SUPERTRAPP performs phase equilibria calculations and gives the thermophysical properties of all phases and the feed.

NIST/ASME Steam Properties Database - SRD 10

Data provided by  National Institute of Standards and Technology

The NIST/ASME Steam Properties Database is based upon the International Association for the Properties of Water and Steam (IAPWS) 1995 formulation for general and scientific use for the thermodynamic properties of water, this updated version provides water properties from the international standards over a wide range of conditions. Version 3.0 incorporates new IAPWS standards adopted in 2008 for the viscosity and for the melting and sublimation curves and in 2011 for the thermal conductivity.

NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP) Version 9 - SRD 23

Data provided by  National Institute of Standards and Technology

**NOTICE: THIS VERSION OF REFPROP (9.1) has been superseded by Version 10: https://doi.org/10.18434/T4/1502528 ** NIST Standard Reference Data 23 contains revised data in a Windows version of the database, including 105 pure fluids and allowing mixtures of up to 20 components. The fluids include the environmentally acceptable HFCs, traditional HFCs and CFCs and 'natural' refrigerants like ammonia. Version9.1 REFPROP 9.1 has replaced the NIST 12 and 14 databases.
