An interlaboratory comparison of Josephson voltage standards has been made among fifteen national, industrial, and military standards laboratories in North America. The comparison was made at 10 V using a set of four travelling Zener reference standards. The uncertainty (2σ) of the comparison is estimated to be 17 parts in 10 9 . The measurements of all participants fall within this uncertainty, indicating that no significant difference has been detected among them.
