Abstract
A series of intercomparisons have been performed with good agreement between the Josephson Array Voltage Standards (JAVS) of the Danish Institute of Fundamental Metrology (DFM), Denmark; Bureau International des Poids et Mesures (BIPM); the Van Swinden Laboratory (VSL), The Netherlands: Physikalisch-Technische Bundesanstalt (PTB), Germany; Laboratoire Central des Industrie Electriques (LCIE), France; Statens Provnings och Forskningsanstalt (SP), Sweden; Centro Espanol de Metrologia (CEM), Spain; and the Israel National Physical Laboratory (INPL), Israel. For most comparisons, full calibration systems were compared using a Zener reference standard as transfer source. All but one laboratory agreed to within 10/spl times/10/sup {/-19} uncertainty (1/spl sigma/) at 1018 V nominal, with one laboratory about 3/spl sigma/ different.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
