Results of Comparison of the Josephson Voltage Standards of the DMDM and the BIPM (part of the ongoing BIPM key comparison BIPM.EM-K10.b)

In cooperation with Bureau International des Poids et Mesures BIPM, DMDM conducted comparison of Serbian National Primary DC voltage Josephson standard to the BIPM Josephson standard.

Accordingly DMDM participated in Key comparison BIPM.EM-K10.b in which participated round 30 countries, until now. Results obtained in this comparison confirmed that the realization of standard of DC voltage unit (Volt) in DMDM is recognized at international level. Degree of equivalency Di=0,1 nV (1Е-11) with expanded uncertainty Ui =3 nV (k = 2) is confirmed.

DMDM has realized national primary DC voltage standard (unit Volt) according to the definition and established traceability of measurements of DC voltage to the fundamental physical constants. This comparison confirmed equivalency of our realization of DC voltage standard to the BIPM realization of Volt.

Results of comparison are published in BIPM Key Comparison Database (KCDB) and could be found at links:
