Comparison of the results of pH measurements in a buffer solution
Аннотации
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.
