Predstavnici Direkcije za mere i dragocene metale, Slobodan Zelenika, šef Odseka za dužinu, optičke veličine i akustiku i Aleksandar Jevremović, metrolog za dužinu, učestvovali su uživo u radu EURAMET Tehničkog komiteta za dužinu (EURAMET TC-L) u  periodu od 13. do 15. oktobra 2025. godine, koji je održan hibridno.

Organizator i domaćin sastanaka bio je Nacionalni metrološki institut Poljske (GUM), a sastanak je održan u prostorijama novoizgrađenog kampusa u Kjelceu.

Sastanku je prisustvovalo oko 50 eminentnih stručnjaka iz većine evropskih zemalja, predstavnika nacionalnih metroloških instituta (NMI), imenovanih instituta (DI), EURAMET i gosti iz drugih RMO.

Na sastanku se razgovaralo o ključnim i dopunskim poređenjima, kao i ostalim EURAMET TC-L projektima, mogućnosti merenja i etaloniranja (CMCs), saradnji u okviru evropskih metroloških mreža (EMN) i digitalne transformacije, projektima evropskog partnerstva u metrologiji (EPM), kao i o svim ostalim relevantnim pitanjima iz oblasti metrologije dužine iz delokruga rada EURAMET TC-L.

Tokom ovog sastanka održana je i otvorena Radionica o izdradnji kapaciteta u okviru redovnog godišnjeg sastanka Evropske metrološke mreže za naprednu proizvodnju (EMN Advanced Manufacturing) – Nanometrology for Emerging National Metrology Institutes, u čijem radu su učestvovali i predstavnici EURAMET TC-L.

Nakon završetka drugog dana sastanka, učesnici sastanka obišli su odabrane laboratorije (uključujući i laboratorije za dužinu) novog metrološkog kampusa GUM u Kjelceu.

Planirano je da se sledeći godišnji sastanak EURAMET TC-L održi u oktobru 2026. godine u organizaciji Nacionalnog metrološkog instituta Švajcarske (METAS).

The representative of the Directorate for Measures and Precious Metals, Dr. Mladen Mirić, a precious metals metrologist in the Department for the Control of Precious Metals, participated in the 93rd Meeting of the Standing Committee of the Hallmarking Convention, which was held on October 9, 2025 in Larnaca, Republic of Cyprus.

The meeting was attended by representatives of all member states of the Hallmarking Convention - 22 member states, one applicant state (Ukraine) and five participants in the technical program (Moldova, Montenegro, North Macedonia, Bosnia and Herzegovina and KRISOS/Spain).

The results of the work of the SK Convention were presented, especially in the form of the use of the Convention mark "SSM" (Common Control Mark), the use of which is not at an enviable level, and whose goal is the safety of end users, as well as increasing the flexibility and cost-effectiveness of business worldwide.

The meeting discussed reports from interlaboratory comparisons held this year (Round Robins), in which Serbia also took an active part and presented excellent results of interlaboratory comparisons.

The participants of the SK Convention had the opportunity to learn about the latest technical achievements in the field of testing and marking of objects made of precious metals. Due to the increasing price of gold on the world stock exchange (120 euros for 1 g of pure gold of fineness 999.9), there is an increasing turnover of objects made in fineness 375/1000, and some countries that do not have this fineness as a legal requirement are introducing it into their legislation.

The next meeting of the SK Convention is scheduled for October 2026 in Geneva, Switzerland.
