The Directorate for Measures and Precious Metals (hereinafter: DMDM), the Section for dimensional, optical quantities and acoustics plans to organize an inter-laboratory comparison (PT scheme) in the field of dimensional sizes for interested accredited and other laboratories:

1. Calibration of micrometers for external measurements

All interested laboratories from the country and region who want to participate in the mentioned comparison can submit their request/application in free form to the address: Directorate for Measures and Precious Metals, 11000 Belgrade, Mike Alasa 14, to email: This email address is being protected from spambots. You need JavaScript enabled to view it. or to email: This email address is being protected from spambots. You need JavaScript enabled to view it., no later than November 15, 2024.

Participating laboratories will bear the costs of the interlaboratory comparison, as well as the costs of transporting the calibration items. The laboratories are obliged to ensure the transport of the standards themselves to the next participating laboratory in accordance with the schedule from the technical comparison protocol.

Along with the request submitted to DMDM, it is necessary to attach proof of payment of the republican administrative tax in the amount of RSD 400.00. DMDM, as a pilot laboratory, after collecting requests, will provide all participants with a technical comparison protocol and a payment order in the amount of RSD 42,200.00 and determine the start date of the mentioned activity.

Representatives of the Directorate for Measures and Precious Metals, Nebojsa Arsenijevic, Head of the Section for verification of measuring instruments, and Sofija Vuković, Junior Advisor in the Group for metrology in chemistry, participated in the metrology summer school as part of EURAMET TC Flow in the period from September 9 to 13, 2024 in Brno, Czech Republic.

The organizer of the summer school was the National Metrological Institute of the Czech Republic (ČMI). 56 participants attended the summer school.

In addition to theoretical lectures, a practical part was also organized, which included demonstration laboratory measurements. The basics of liquid volume measurements, liquid and gas flow, as well as air flow velocity measurements are presented. The participants were also introduced to calibration methods, as well as other documents and standards related to the traceability of the mentioned measurements.

The representative of the Directorate for Measures and Precious Metals Ljiljana Micic, Head of the Group for volume and flow, attended the meeting of the working group for measures (WGMI), which was held online on September 12, 2024.

The organizer of the meeting was the Working Group for Benchmarks at the European Commission (WGMI), which has 96 members.

The meeting was attended by representatives of organizations of interested parties and appointed representatives of countries that have the following statuses in the European Commission:

- 01 Leader

- 02 Committee members

- 03 EFTA Competent Authority

- 04 EU MS Authority not Committee Member

- 05 Candidate Country Observer

- 06 Industry and International Organization Observer

Planned amendments to the MID European Directive on benchmarks were presented at the meeting. The chairman of the working group, Zsuzsanna DAKAI, emphasized that the amendments are necessary, because the subject and basic requirements of the MID European directive on standards have not been changed for 20 years. Also, the MID European Directive on meters does not include fast charging stations for electric vehicles, nor hydrogen vehicle charging stations, and the requirements cannot be applied to smart meters.

There is a need to amend the MID European Benchmark Directive as soon as possible, in order to avoid the discontinuity of the single market and the associated costs, as well as to support the introduction of "clean mobility" (AFIR - Alternative Fuels Infrastructure Regulation) and achieve the goals in related to energy efficiency (EU directive 2023/1791).

Representatives of the Directorate for Measures and Precious Metals, Dragana Zivkovic-Micunovic, employed in the Group for Control of Precious Metal Articles and PhD Mladen Miric, metrologist for precious metals in the Group for Control of Precious Metal Articles, participated in the 92nd meeting of the Standing Committee of the Convention (hereinafter: SK Convention) on the control and hallmarking of objects made of precious metals (Hallmarking Convention), which was held on September 5 and 6, 2024 in Vicenza, Italy.

The meeting was attended by representatives of member countries of the SC Convention - 54 officials representing 20 of the 22 member states, 1 applicant state (Ukraine) and 2 participants of the technical program (Moldova and KRISOS/Spain).

The results of the SK Convention's work were presented, especially in the form of the increasing use of the Convention trademark "SSM" (Common Control Mark), whose goal is the safety of end users, as well as the flexibility of business worldwide.

At the meeting, reports from interlaboratory comparisons held this year (Round Robins, RR 57&58) were discussed, 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 get acquainted with the latest technical achievements in the field of testing and stamping of objects made of precious metals. This year, the inter-laboratory testing of marking ("RR on Marking"), with mechanical and laser methods, was launched.

The next meeting of the SC Convention is scheduled for October 2025. On that occasion, the fiftieth anniversary of the existence of the Convention will be marked.
