International Bilateral Inter-laboratory Comparison Measurements Between Public Institutions for Dry-Block Calibrator and Thermometer Calibrations

Abstract

This study examines the efficacy of interlaboratory comparison tests in evaluating the calibration of analogue bimetal thermometers and dry-block calibrators. These instruments play a pivotal role in various industrial applications involving temperature measurement and calibration. The Turkish Standards Institution (TSE) organized a bilateral interlaboratory comparison with a foreign public authority laboratory, focusing on the calibration of a dry-block calibrator and an analogue bimetal thermometer. Interlaboratory comparison tests are expected to reveal consistent calibration results with E_n values less than one, signifying comparable calibration outcomes across different laboratories. While measurement uncertainties may vary between laboratories, these differences are anticipated to remain within acceptable limits as defined by international standards. Participation in interlaboratory comparison tests enhances the technical competencies of laboratories, particularly in calibration accuracy and uncertainty management.
