Ministry of Economy in the period from October 20 to November 10, 2023 conducts a public hearing on the Draft Law on Amendments to the Law on Items Made of Precious Metals.

The Ministry of Economy invites state authorities, the professional public, as well as other interested parties to familiarize themselves with the text of the Draft Law during the public discussion and give their comments, proposals and suggestions.

Remarks, proposals and suggestions are submitted to the Ministry of Economy by e-mail to the e-mail address: This email address is being protected from spambots. You need JavaScript enabled to view it., as well as by mail to the address Ministry of Economy, Sector for Quality and Product Safety, Kneza Milosa 20, 11000 Belgrade, with the indication "Public hearing on the Draft Law on Amendments to the Law on Items Made of Precious Metals".

The representative of the Directorate for Measures and Precious Metals, Ljiljana Micic, head of the Volume and Flow Group, actively participated on October 19, 2023 in the meeting of the Subcommittee for Liquid Volume of the EURAMET Technical Committee for Flow (EURAMET TC-F), which was held via video - conferences.

The organizer of the meeting was the chairman of the Subcommittee for the volume of liquids EURAMET TC-F Elsa Batista, and the meeting was held in the presence of 20 eminent experts, representatives of national metrology institutes (NMI).

At the meeting, the statuses of the ongoing and completed key and supplementary comparisons were presented, as well as the plan of the planned international comparisons.

The revision of the guide EURAMET cg 21 "Guidelines on the Calibration of Standard Capacity Measures Using the Volumetric Method" has been completed and is expected to be published in early 2024, when it is planned to start the revision of the guide EURAMET cg 19 "Guidelines on the Determination of Uncertainty in Gravimetric Volume Calibration".

Ljiljana Mićić, in her capacity as the coordinator of the EURAMET project 1533 - Comparison of piston operated volumetric instruments, presented information on the supplementary comparison in which 14 national metrology institutes participate.

On Tuesday, October 17, 2023, the Directorate for Measures and Precious Metals (hereinafter: DMDM) hosted the students of the Technological and Metallurgical Faculty of the University of Belgrade.

On that occasion, students were introduced to the importance of metrology, as a science of measurements, which is present in all areas of human activity, the importance and method of ensuring metrological traceability to the international level, as well as the long tradition of metrology in Serbia. Through the promotional film, the importance and role of DMDM, as a national metrology institution, its competences, jobs and tasks in the field of metrology were presented.

The expert visit included a tour of laboratories for metrology in chemistry, thermometry, large and small volumes, as well as a laboratory for control on precious metals articles.

During the visit to the laboratories, the students had the opportunity to become more familiar with the measurement and calibration possibilities of DMDM, the international EMPIR projects in which DMDM participates, as well as other tasks performed as a national metrology institute.
