dc.description.abstract As a result of the increasing need to study the choice of the assigned value during the inter-laboratory comparisons is becoming more and more relevant. Since the assigned value is a reference point when comparing the results of the participants of the qualification test. Frequently, qualification verification providers face a number of problems when choosing the assigned value. An incomplete analysis of the results of interlaboratory comparisons will lead to an inaccurate assessment of the competence of the laboratory, which contributes to the revocation of the certification of the accreditation of the laboratory participant. This article attempts to provide a complete statistical analysis of the results of interlaboratory comparisons from the beginning to the end of the tour with the content of all statistical analyses recommended in GOST ISO/IEC 17043-2013. The results of interlaboratory comparisons conducted in testing laboratories of Kazakhstan aimed at ensuring metrological traceability of pH measurements in a buffer solution are presented. The reference values of the buffer solution are determined in the state scientific metrological center. ru
