kindly invite you to participate

in the 22th International scientific and technical seminar

“Uncertainty of measurement: scientific, applied, regulatory and methodical aspects” (UM-2025)

The approximate range of issues that will be discussed:

  • development of the theoretical fundamentals of modeling and empirical approaches to the measurement uncertainty evaluation;
  • processing of the results and evaluation of measurement uncertainty during testing, calibrations, comparisons;
  • validation of methods of calibration and testing;
  • improving the regulatory base of measurement uncertainty evaluation;
  • automatization of processing of the results and evaluation of measurement uncertainty;
  • organizing and conducting interlaboratory comparative tests, processing their results;
  • training (including e-learning) on the issues of estimation of measurement uncertainty.

Participants of the seminar are invited to submit the abstracts (1-2 full page) in accordance with the template before November 30, 2025 to e-mail: newzip@ukr.net. must be attached to the abstracts a table of information about the authors.

Abstracts of reports will be published by the beginning of the seminar.

Presentations should be reported on November 10-11, 2025 at an online meeting.

Participation in the seminar is free.

Extended versions of the reports, from among those presented at the seminar, following peer review, will be published as articles in English in nearest issues “Metrology and instruments” (M&I) (included in the List of Scientific Professional Editions of Ukraine in category “Б”.

On December 10–11, 2025, the 22nd International Scientific and Technical Seminar “Uncertainty of Measurements: Scientific, Applied, Regulatory and Methodological Aspects” (UM-2025) was held. The co-founders of the UM 2025 seminar are Kharkiv National University of Radio Electronics (Ukraine), the National Scientific Center 'Institute of Metrology' (Ukraine), Technical University of Sofia (Bulgaria) and the Union of Metrologists in Bulgaria.

The following scientific and practical topics were discussed at the UM 2025 seminar: development of theoretical foundations of model and empirical approaches to measurement uncertainty evaluation; processing of results and evaluation of measurement uncertainties during testing, calibration, and verification; validation of testing and calibration methods; automation of result processing and uncertainty evaluation in measurements; improvement of the regulatory framework for measurement uncertainty evaluation; organization and conduct of interlaboratory comparison tests, processing of their results; specifics of training in measurement uncertainty evaluation issues.

The seminar brought together researchers from several countries (Poland, Ukraine, Bulgaria, Italy, and the USA), as well as PhD students and students from Ukrainian universities. A total of sixty papers were presented. Following the event, a Theses of reports UM 2025 PDF (Sofia: Softrade. 2025, 92 p, ISBN 978-954-334-284-6) was published.
