Abstract

A three-way comparison of the 10 V voltage reference standards of the BIPM and the NIST sites in Gaithersburg and Boulder was carried out from October 1998 to January 1999 by using three Zener travelling standards. An important reason to make this comparison is to provide a robust link between the comparisons of Josephson voltage standards via Zeners in NORAMET and similar comparisons underway in other regional metrology organizations such as EUROMET, COOMET and APMP in which BIPM has participated. The comparison is designed to test the techniques used to compare Josephson voltage standards via Zener travelling standards, in particular, the veracity of corections of the Zener voltages for temperature and pressure dependence. The differences among the 10 V calibrations traceable to the three Josephson voltage standards measured by shipping three Zener standards, lie within 0.26 V or 2.6 parts in 10⁸.
