IUPAC/CITAC Workshop on
Quality of Test Results for Conformity Assessment
of a Chemical Composition

What is Good and What is Bad?

January 21, 2019
Kfar Maccabiah, Ramat Gan

The main goal of the workshop is discussion of the quality parameters of test (chemical analytical) results in pharmaceutical industry, environmental analysis, metallurgy and other fields, necessary for conformity assessment of a material or object. This discussion will include the following topics:

  • use of measurement uncertainty as a parameter of quality of test results
  • evaluation of correlation of test results of concentrations of different components as another quality parameter of the results
  • influence of measurement uncertainty and correlation of the test results on probabilities of false decisions on conformity of the material or object
  • ways of minimization of measurement uncertainty to its target value and quality improvement

Dr. Narine Oganyan
In the majority of cases conformity assessment is based on measurement results, since human activity is related to measurements and measurement results are considered as the main source of information about the characteristics / parameters of any object or subject. Since true values of measurement results are unknown, the Guide to the Expression of Uncertainty in Measurement (GUM) suggests to express a measurement result as the best estimate of the measurand, associated with the measurement uncertainty. Measurement uncertainty is one of the important quality characteristics of any measurement. When measurement uncertainty is large, the probability of a false decision in conformity assessment is large also. As the measurement uncertainty depends on such factors as the measurement procedure, operator qualification, parameters of the measurement system, each testing laboratory should understand which measurement uncertainty is fit for which purpose, and when there is the necessity to reduce the measurement uncertainty.
