Quantifying Uncertainty in Analytical Measurement, 3rd Edition.

Abstract

This Guide gives detailed guidance for the evaluation and expression of uncertainty in quantitative chemical analysis, based on the approach taken in the ISO “Guide to the Expression of Uncertainty in Measurement” [H.2]. It is applicable at all levels of accuracy and in all fields - from routine analysis to basic research and to empirical and rational methods (sees section 5.5.). Some common areas in which chemical measurements are needed, and in which the principles of this Guide may be applied, are: • Quality control and quality assurance in manufacturing industries. • Testing for regulatory compliance. • Testing utilising an agreed method. • Calibration of standards and equipment. • Measurements associated with the development and certification of reference materials.
