Abstract

An intercomparson of 10 pF and 100 pF capacitance standards has taken place within the framework of EUROMET. The intercomparison piloted by NPL, has involved seventeen laboratories, including several who are members of other regional organisations. The results presented in this report appear to show that there are significant differences between some laboratories' representation of the farad. However, the agreement demonstrated by the intercomparison provides confidence in maintaining traceability for the farad either via a calculable capacitor or via a quantum Hall reference standard and the consensus value of the von Klitzing constant (RK-90).
