database Manager)
2. Type of comparison (key, supplementary):
Supplementary
3. Relevant CCEM Working Group (WGLF or
GT-RF): WGLF
4. This comparison will be carried out under the
auspices of (CCEM, BIPM or RMO): RMO
If RMO, specify name: EURAMET
5. Pilot Laboratory:
PTB
6. Comparison support group member names and
email addresses:
Alexander Katkov, A.S.Katkov@vniim.ru

7. Participating institutes, comprising the pilot institute (states and economies):
If bilateral,

indicate here:
(Slovakia), UME (Turkey), VMT/FTMC (Lithuania), BIPM (International)
No
8. Measurand(s) and nominal value(s):
Josephson voltage standards at 10 V
9. Description:
A comparison of Josephson array voltage standards at the 10-V level will be carried out. It is planned as
RMO KC supplementing BIPM.EM-K10.b. A portable Josephson array voltage standard of VNIIM will be
used as travelling standard. It provides a stable and isolated output voltage like a Zener reference but it is a
quantum standard with low noise. Therefore, the portable Josephson array voltage standard allows
comparisons with an uncertainty of less than 10 nV.The comparison will be organized in a loop. The
portable Josephson array voltage standard will be accompanied and operated by a specialist of VNIIM.
Approximately two days should be sufficient for each participant to measure the output voltage of 10 V.
10. Additional remarks:
11. Proposed measurement start date and timescale: 2014-07-01 – 2015-07-01
