Pilot study: Zn fixed point realisation
Project Description
Perform an investigation of equivalence of Zn fixed point realisation in 5 Euramet NMIs:
LNE-CNAM, NPL, PTB, SMD, VSL.
The major sources of uncertainties in fixed points realisations will be investigated by using different SPRTs, different furnaces and different bridges.
Measurements will be performed in SMD lab. Each lab will provide a Zn cell, both open and closed cells will be compared. The cell will be compared to the corresponding national reference either before or after measurements at SMD.
