Abstract

In September 2004, the Bureau International des Poids et Mesures (BIPM) began a new round of its large-scale international comparison of Josephson array voltage standards with national metrology institutes. As an option, it offers a new simplified measurement procedure, whereby the other participants simply measure the BIPM array as if it were an electronic voltage standard. This presentation discusses the accuracy of JAVS, the problems that were encountered in the new round, and how most of them were resolved
