In the premises of the Directorate for Measures and Precious Metals (hereinafter: DMDM), in the period from June 12 to 13, 2025, a collegial assessment (on-site visit by peer) was carried out in the area of ​​mass. The evaluation was carried out by Bianka M. Stoilkovska, technical expert of the Macedonian National Institute for Metrology - Bureau of Metrology (BoM) in the field of quality and mass, EURAMET contact person for TC-Q and TC-M.

Collegial evaluation was carried out within EURAMET Project no. 1208 Peer visits and reviews of QMSs in BIM, MBM, IMBIH, LATMB, BoM and DMDM, and in accordance with the document EURAMET Guide for on-site visits by peers in the framework of CIPM MRA (G-TCQ-PRC-006, version 3.0), according to the standard SRPS ISO/IEC 17025:2017. The evaluation checked the technical requirements of calibration laboratories in relation to the published calibration capabilities (CMCs) in the KCDB BIPM database.

Representatives of DMDM ​​were:

• Dragan Pantić, contact person for TC-Q and TC-M, technical expert in the field of quality and mass;
• Jelena Ivandić, quality manager.

The two-day evaluation took place in a collegial atmosphere, through interactive work and the exchange of expert knowledge. The observations, which are the basis for improvement, are given in the report from the collegial visit, and the results of this assessment will serve as the basis for confirming the calibration possibilities (CMCs) of DMDM ​​in the KCDB BIPM database.

U prostorijama Direkcije za mere i dragocene metale (u daljem tekstu: DMDM), 13. avgusta 2025. godine, realizovano je kolegijalno ocenjivanje (on-site visit by peer) u oblasti gustine tečnosti.

Kolegijalno ocenjivanje sprovedeno je od strane tehničkog eksperta Turskog nacionalnog instituta za metrologiju (TUBITAK-UME) na osnovu EURAMET Projekta br. 1208, prema standardu ISO/IEC 17025:2017, proveravajući kako zahteve sistema kvaliteta, tako i tehničke zahteve laboratorije za etaloniranje u pomenutoj oblasti za objavljene mogućnosti etaloniranja (CMCs) u KCDB bazi BIPM.

DMDM, as a pilot laboratory, after collecting requests, will deliver to all participants a technical protocol of comparison and an order for the payment of the republic's administrative fee in the amount of RSD 43.800,00 (20 working hours).

At the premises of the Directorate of Measures and Precious Metals (hereinafter: DMDM), a peer review (on-site visit by peer) in the field of Time and Frequency was conducted from 24 to 25 December 2025. The review was carried out by Osman Šibonjić, Technical manager of the Laboratory for Time and Frequency at the Institute of Metrology of Bosnia and Herzegovina, contact person in EURAMET TC-TF, and technical assessor and expert in the field of Time and Frequency.

The DMDM representatives were:

• Snežana Renovica, Head of the Time and Frequency Group and contact person in EURAMET TC-TF;
• Dragana Dragutinović, Deputy Head of the Time and Frequency Group;
• Jelena Ivandić, Quality Manager.

The peer review was conducted within the ongoing EURAMET project 1208 – Peer visits and reviews of QMSs in BIM, MBM, IMBiH, LATMB, BoM and DMDM, in accordance with the CIPM MRA and EURAMET rules, the requirements of ISO/IEC 17025:2017, and the relevant reference documents in the field of Time and Frequency for the published Calibration and Measurement Capabilities (CMCs) in the BIPM KCDB.

The outcome of the peer review, which was carried out in a collegial atmosphere with an interactive exchange of expert knowledge, is documented in a report that has been submitted to the Secretariat of the EURAMET Technical Committee for Quality (EURAMET TC-Q).
