Abstract

Abstract This article presents a method for assessing the accuracy of the measurements obtained at different tests conducted in laboratories by implementing the interlaboratory comparison method (organization, performance and evaluation of measurements of tests on the same or similar items by two or more laboratories under predetermined conditions). The program (independent software application), realised by the author and described in this paper, analyses the measurement accuracy and performance of testing laboratory by comparing the results obtained from different tests, using the modify Youden diagram, helping identify different types of errors that can occur in measurement, according to ISO 13528:2015, Statistical methods for use in proficiency testing by interlaboratory comparison. A case study is presented in the article by determining the chemical composition of identical samples from five different laboratories. The Youden diagram obtained from this study case was used to identify errors in the laboratory testing equipment.
