The Directorate for Measures and Precious Metals (hereinafter: DMDM), Group for Time and Frequency, plans to organize an interlaboratory comparison (PT scheme) for interested accredited and other laboratories in the field of time and frequency, subfield of time interval, namely:

1. Calibration of the stopwatch.

All interested laboratories that wish to participate in the mentioned comparison can submit a request/application on the form Request for issuing a report on inter-laboratory comparison (https://www.dmdm.rs/rs/obrasci), to the address: Directorate for Measures and Precious Metals, 11158 Belgrade, Mike Alasa 14 or to email: This email address is being protected from spambots. You need JavaScript enabled to view it., no later than February 16, 2026. With the request submitted to the DMDM, it is necessary to attach proof of the payment of the republican administrative fee in the amount of RSD 420,00.

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 in accordance with the schedule from the technical comparison protocol. 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).
