The representative of Directorate of  Measures and Precious Metals, Dr Jelena Bebić, Head of Group for Metrology in Chemistry, from 6.  to 8. February 2024, has actively participated in the work of the EURAMET Technical Committee on Metrology in Chemistry (EURAMET TC-MC) as well as at the subcommittee meeting for organic and bio analysis in  Delft, Netherlands.

The EURAMET TC-MC meeting was attended by over 60 eminent experts, representatives of the National Metrology Institutes (NMI) and designated laboratories from most European countries. The host and the organizer of the meeting was VSL, National Metrology Institute of Netherlands.

Reports from all subcommittees within TC-MC, the status of current EPM projects, current European Metrology Networks (EMNs), projects related to various types of cooperation between National Metrology Institutes, key comparisons, as well as information regarding the status of  submitted and published calibration and measurement capabilities  (CMCs) were discussed at the meeting.

The representative of the Directorate for Measurements and Precious Metals (hereinafter: DMDM), Boban Zarkov, Metrologist for Quantities of Optical Radiation - Coordinator, in the period from January 22 to 26, 2024, participated in the work of the EURAMET Technical Committee for Photometry and Radiometry ( EURAMET TC-PR), which this year was held hybridly in Istanbul, Turkey.

The organizer of the meetings was the National Metrology Institute of Turkey - UME Tubitak. The meeting was attended by 19 participants from national metrology institutes, 12 guests from institutions that actively participate in the work of EURAMET and 13 metrologists who participated in the work of the technical committee via the Internet.

During this meeting, a workshop on single-photon radiation sources and a retrospective of previous research through the EURAMET project SEQUME was held, including all project partners as well as interested parties from the field of industry and telecommunications.

Also, a seminar was held in the form of a training, where the participants were shown the Toolbox used by the pilot laboratories in Euramet's key comparisons. Mathematical models of the final result of the participants, the use of the Phython programming language, as well as the Rulebook on the selection of a pilot laboratory were discussed.

The meeting discussed key comparisons, as well as the measurement results that DMDM submits to this technical committee in a timely manner.

By participating in the work of EURAMET TC-PR and raising metrological education through constant contacts with leading laboratories in the world, better and better metrological work of the laboratory for optical sizes and acoustics DMDM is enabled, as well as raising the quality of services in the field of photometry and radiometry.
