Abstract :
An intercomparison of standard capacitor of value 10 pF has been carried out between NPL (India) and Physikalisch-Technische Bundesanstalt (Germany) under the PTB-NPL Cooperation programme. The measurements of a 10 pF silica capacitor at the frequency 1592 Hz for two different temperatures agreed within 0.15 ppm.
