Abstract :
We describe dissipation factor measurements of 10-pF fused-silica capacitance standards from 50 Hz to 20 kHz using a toroidal cross capacitor and a 10-pF nitrogen-filled capacitor as the references. The relative combined standard uncertainties are 0.56 10-6, 0.16 - 10-6, and 0.26 10-6 at 100 Hz, 1 kHz, and 10 kHz, respectively
