Abstract
This paper describes the work done at the NPL, UK to establish a 10 V standard based on an array of Josephson junctions. The system is described and results obtained with the system are presented. A preliminary uncertainty budget is also presented which shows the system to be accurate to around 4 parts in 10/sup 9/ (quoted at a confidence level of at least 95%).
