An indirect comparison between the 10 V Josephson array voltage standards of the BNM/LCIE and the BIPM has been carried out using Zener-diode based voltage references as transfer standards. The results show an agreement of 5 parts in 10{sup 9} with an uncertainty (1{sigma}) of 3 parts in 10{sup 9}, mainly due to instability of the Zener references. A direct comparison is to be carried out early in 1994 to avoid this limitation.
