Abstract

A comparison of the 10 V Josephson array voltage standard of the Bureau International des Poids et Mesures (BIPM) was made with that of the National Institute of Standards and Technology (NIST), USA, in March 2009. The results are in very good agreement and the measured overall standard relative uncertainty is 1.2 parts in 10^10.
