METHODOLOGY FOR IMPROVING INTERLABORATORY COMPARISONS FOR ASSESSING PHYSICAL FACTORS IN THE WORKPLACE

This article covers the implementation of the requirements of the interstate standard "General Requirements for the Competence of Testing and Calibration Laboratories" in the context of interlaboratory comparisons aimed at assessing the lighting of workplaces. The regulatory framework, including guidelines and international studies in this area, is analyzed, which helps to identify key methodological gaps. The essence of interlaboratory comparisons, their role in the activities of testing laboratories and the problems that arise during their formal implementation are considered, and a review of relevant scientific studies on the topic of the study is provided. The article presents the results of the author's experimental study, showing significant discrepancies in the measurement results with different selection of measurement points for illumination parameters. The author's methodology for improving interlaboratory comparisons is presented, aimed at increasing the reproducibility of measurements due to a standardized approach to the selection of measurement points. Recommendations are given for the application of the proposed methodology in testing laboratories, which helps to increase the accuracy of measurements and improve metrological control in the field of assessing the illumination of workplaces.
