Content of the short-term learning experience
Participants learn about the theoretical fundamentals of measurement errors and measurement uncertainty, relation between measurement uncertainty and product tolerances, and an internationally standardized measurement uncertainty evaluation procedure is presented to them in detail. The presented procedure is supported by examples of evaluating measurement uncertainty in calibration of dimensional measuring instruments and in the control of production processes (measurement of geometric characteristics of products). The acquired theoretical knowledge is complemented by practical examples of experimental and analytical evaluation of contributions to measurement uncertainty in various measurement procedures and on various measuring instruments. The content of the practical work can be adapted to the wishes of the users according to the requirements in their working environments. The practical part of the training is carried out in the calibration laboratory, which has the status of the holder of the national standard for length in Slovenia ("Slovenian meter"). The staff of the laboratory has excellent competence and experience in the field of calibrating measuring instruments and developing measurement methods and procedures.

Dr. Jasna Tompa
The colleague is an assistant in the Laboratory for Production Measurements and is scientifically engaged mainly in developing demanding calibration procedures and executing calibrations at the highest accuracy level. Her bibliography includes four original scientific articles in the last five years. One of these metrological, and deals with experimental determination of uncertainty in the calibration of gauge blocks. The development work of the colleague is focused on creating and updating calibration procedures. In the last five years, independently or in cooperation with colleagues from the Laboratory for Technological Measurements, she has published twenty calibration procedures, which are also accredited by the Slovenian Accreditation. She also maintains a quality management system in the national laboratory, which she successfully presented at the EURAMET technical committee for quality in 2024.
