Based on the Law on Time Calculation ("Official Gazette of the SCG", No. 20/06), daylight saving time in 2025 begins on March 30, 2025 at 2 h, 00 min, 00 s, so that, moving by one hour ahead, the time at 2 h, 00 min, 00 s counts as 3 h, 00 min, 00 s.

On March 19, 2025, the International Bureau of Weights and Measures (BIPM) published a new measurement and calibration capability (CMC) of the Directorate of Measures and Precious Metals in the field of thermometry, sub-field of temperatures, in the KCDB 2.0 database.

The measurement capability of calibrating industrial resistance thermometers in the temperature range from 550 ⸰C to 660 ⸰C using the comparison method has been published.

More information about the CMC Directorate for Measures and Precious Metals in the field of thermometry and other areas can be found in the BIPM database  KCDB .

The representative of the Directorate for Measures and Precious Metals, Dr. Dušan Matijašević, metrologist in the Electrical Quantities Group, participated in the work of the Technical Committee TC 12 Project Group - Instruments for Measuring Electrical Quantities, as well as in the meetings of three subcommittees: P1 Electricity Meter - Alternating Current (AC) - Alternating Current Meters, R3 Electric Vehicle Supply Equipment - Supporting Equipment for Electric Vehicles and R4 - DC Electricity Meters - Direct Current Meters, which were held in Prague, Czech Republic.

The meetings were organized by the Czech Metrology Institute (ČMI). The meetings were attended by over 40 participants, representatives of national metrology institutes, national regulatory bodies and equipment manufacturers from countries around the world.

The meetings reviewed reports from the three subcommittees within TC-12, as well as the status of current documents. Recommendations and standards related to the relevant areas were reviewed and harmonized.

The next meeting of the OIML Technical Committee TC 12 Project Group is planned to be held in June 2025.

From March 11 to 14, 2025, the International Congress of Metrology CIM 2025 was held in Lyon, France.

At this congress, a poster was presented by Boban Zarkov, metrologist for optical quantities at the Directorate for Measures and Precious Metals, and Dr. Veljko Zarubica, technical director of the accredited laboratory Analysis doo. This poster presents a new type of material that can be used as a certified reference material for the calibration of analytical instruments, spectrophotometers in the UV range, as well as nano drop spectrophotometers. The material was characterized, including short-term and long-term stability, homogeneity, temperature dependence and measurement uncertainty budget.

Publication of this work in scientific journals is planned in the coming months.

Representatives of the Directorate for Measures and Precious Metals, Dr. Jelena Bebić, Head of the Group for Metrology in Chemistry, and Luka Gažević, metrologist in the Group for Metrology in Chemistry, participated in the work of the EURAMET Technical Committee for Metrology in Chemistry (EURAMET TC-MC) from 4 to 6 February 2025, as well as in the meetings of the Subcommittee on Organic and Bioanalysis and the Subcommittee on Gas Analysis, which were held in Boras, Sweden.

The meeting was organized by the National Metrological Institute of Sweden (RISE). The meetings were attended by over 60 participants, representatives of national metrology institutes and designated institutes from most European countries.

The meetings discussed reports from all subcommittees within the TC-MC, the status of current ERM projects, current European Metrology Networks (EMNs), projects related to various forms of cooperation between national metrology institutes, key comparisons, as well as information regarding the status of reported measurement and calibration capabilities (CMCs).

Ideas for new projects within the EPM program were presented, as well as the upcoming celebration of the 150th anniversary of the signing of the Metre Convention, which will be organized by the BIPM in May 2025.

The next annual meeting of the EURAMET Technical Committee for Metrology in Chemistry (EURAMET TC-MC) is planned to be held in Ljubljana, Slovenia.

In accordance with Article 5 of the Regulation on the program, conditions and manner of taking the professional exam for measuring instrument verification ("Official Gazette of the Republic of Serbia", No. 2/17), the Directorate for Measures and Precious Metals has published a list of literature for the preparation of the Professional Exam for Measuring Instrument Verification.
