Uncertainties
Uncertainties listed in all tables and output files of the
ThermoData Engine software represent estimates of the
Combined Expanded Uncertainty (with
95% Level of Confidence) for the property value.
The Combined Expanded Uncertainty and Level of Confidence are defined in the article:
- Chirico, R. D.; Frenkel, M.; Diky, V. V.; Marsh, K. N.; Wilhoit, R. C. ThermoML - An XML-Based Approach for Storage and Exchange of Experimental and Critically Evaluated Thermophysical and Thermochemical Property Data. 2. Uncertainties. J. Chem. Eng. Data 2003, 48, 1344-1359.

The definitions are in accord with those provided in the
U. S. Guide to the Expression Of Uncertainty in Measurement, which is also known as the
