A dynamic physical properties (DPP) library of a new type of architechture is discussed. The library consists of a property evaluation program and a database which contains original experimental data and regression models, as well as statistical and graphical information for assessing their quality. The property evaluation program identifies 'smooth'regions, where optimal regression models are fitted to the data, and discontinuities (transient regions), where statistically valid models cannot be obtained. The property evaluation program and the databases can be continuously updated to include the current state of the art regression models, experimental data, and regression techniques. The advantages of the DPP library structure over the traditional correlation libraries are demonstrated using an example of correlating heat capacity for a solid substance, where the experimental data includes smooth and transient regions.
