 | | | | All values of uncertainty are the combined expanded uncertainty with a level of confidence of 95% estimated as a part of the IUPAC Project "Ionic Liquids Database". Information provided by the authors in the text of the articles is considered in the uncertainty evaluation process. Numerous issues with regard to synthesis, purification, analysis, and measurement details for these materials often make estimation of uncertainties impossible without numerous assumptions. The listed values of the combined expanded uncertainties should be considered preliminary, and are subject to change as more information becomes available and analysis of the experimental data continues. |
| | Incorporation of the combined expanded uncertainties assessed on the basis of the GUM in this database was recommended by the IUPAC Task Group for the Project, "Thermodynamics of ionic liquids, ionic liquid mixtures, and the development of standardized systems." |
| | Terminology related to specification of uncertainties is as defined in the Guide to the Expression of Uncertainty in Measurement (“the GUM”). [1] These ISO recommendations were adopted with minor editorial changes as the U.S. Guide to the Expression of Uncertainty in Measurement. [2] The interpretation of the GUM specifically for thermophysical and thermochemical property data has been published [3]; in particular, see pages 1356-1357. |

This Guide was prepared by ISO Technical Advisory Group 4 (TAG 4), Working Group 3 (WG 3). ISO/TAG 4 has as its sponsors the BIPM, IEC, IFCC (International Federation of Clinical Chemistry), ISO, IUPAC (International Union of Pure and Applied Chemistry), IUPAP (International Union of Pure and Applied Physics), and OIML. Although the individual members of WG 3 were nominated by the BIPM, IEC, ISO, or OIML, the Guide is published by ISO in the name of all seven organizations. |
