The representative of the Directorate for Measures and Precious Metals (hereinafter: DMDM), Boban Zarkov, metrologist for optical radiation quantities - coordinator, attended the ETraceABS project meeting, which was held in Lisbon from November 18 to 19, 2025.

The meeting was attended by 14 representatives of national metrology institutes and about ten metrologists who attended the meeting online.

During this meeting, topics were presented on the improvement of measurement systems and measurement results up to the 18th month according to the project program, measuring the dependence of the influence of ultraviolet radiation on the change in solution absorption and measurement results related to the influence of short-term and long-term stability of the solution.

DMDM representative, Boban Zarkov, presented the multi-device measurement method and showed how DMDM ​​measures, verifies and compares spectral bandwidth values ​​on devices.

The meeting participants had the opportunity to learn about the challenges that can occur during the measurement and sampling process and to see how problems can be solved or their impact minimized.
