USSR National Standard Reference Data Service (NSRDS). The system was developed in 1976-1980 in the All-Union Research Center of NSRDS (now Russian Research Center on standardization, information and certification of raw materials, materials and substances) in Moscow. It provides specialists with attested databases, formed on the basis of standard and recommended reference data. The data of the lUPAC Commission on Thermodynamics, the International Association for the Properties of Steam, the U.S. National Bureau of Standards and other authenticated foreign data are used in the system as well. The informadon blocks of the system are sets of program modules, being the mathemadcal models of substances, and the blocks of numerical data for each substance. The basis for the model of a substance is a unified equadon of state for gas and liquid in the form of a double power expansion of the compressibility with respect to density and temperature. The principles of the molecular-kinetic theory and the dependence of the excess viscosity and thermal conductivity on density and temperature are used for the calculation of the transport properties. 

NIST/ASME Steam Properties Database versiou 2.21 http //www.nist.gov/srd/nistlO.cfm (accessed November 10, 2010) (purchase required). Thermophysical properties include in the STEAM Database temperature, Helmholtz energy, thermodynamic derivatives, pressure, Gibbs energy, density, fugacity, thermal conductivity, volume, isothermal compressibility, viscosity, dielectric constant, enthalpy, volume expansivity, dielectric derivatives, internal energy, speed of sound, Debye-Hlickel slopes, entropy, Joule-Thomson coefficient, refractive index, heat capacity, surface tension. The STEAM database generates tables and plots of property values. Vapor-liquid-solid saturation calculations with either temperature or pressure specified are available.
