CONFORMITY ASSESSMENT OF TEMPERATURE MEASURING DEVICES USED IN FORENSIC SCIENCE LABORATORIES UNDER ISO/IEC 17025: 2017

Calibration is an expectation for quality management systems as well as a need for laboratories. If there is a need to measure the size in the laboratory, there is also a need to determine whether the measuring instrument used there is measuring with the desired accuracy.In our study, the suitability of the digital thermometer, which is one of the devices used in the forensic science laboratory during the examination of the evidence, was examined within the scope of ISO / IEC 17025: 2017 standard.The temperature of the environment is very important during the analysis of the evidence.Therefore, it is important to determine the measurement uncertainty and confidence interval in the thermometer that measures this temperature.For this reason, in our study, the calibration procedures were carried out by selecting the digital thermometer device and using the calibration method compared to the reference.Uncertainty budgets were prepared by calculating the measurement uncertainty parameters one by one. Conformity assessment was made according to the measurement results.
