OBJECT OF THE RESEARCH — processes of statistical evaluation of the results of interlaboratory comparisons and key comparisons.
SUBJECT OF THE RESEARCH — statistical criteria, methods for processing measurement results, decision-making algorithms and software tools for their implementation.
PURPOSE OF THE RESEARCH — to develop an approach to selecting statistical criteria for evaluating ILC and key comparison results, algorithms for calculating evaluation indicators and making decisions, and software for automated calculations.
The report presents the results of the interim R&D stage. Regulatory documents governing interlaboratory comparisons (ILCs) were analyzed. Statistical criteria for evaluating ILC results were investigated and their selection for different types of comparisons was substantiated.
A mathematical model and algorithms for calculating statistical criteria, including measurement uncertainty evaluation, were developed. A decision-making algorithm was developed for classifying participating laboratory results as satisfactory, conditionally satisfactory or unsatisfactory. The structure and functional requirements of the software were defined, and the software was tested and validated.
The developed algorithms and software were practically applied to two ILCs involving the R&D participants. The results demonstrated the possibility of automated statistical processing of ILC results and supporting decisions on laboratory competence.
IMPLEMENTATION: the developed algorithms and software were tested, validated and practically applied during two ILCs.
FIELD OF APPLICATION: 72.19; ILC organizers, national metrology institutes, calibration and testing laboratories, accreditation and technical assessment bodies.
KEYWORDS: INTERLABORATORY COMPARISONS, KEY COMPARISONS, TESTING AND CALIBRATION LABORATORIES, STATISTICAL CRITERIA, MEASUREMENT RESULTS, DECISION-MAKING ALGORITHM, SOFTWARE TOOLS.
