capacitor, giving the measured direct capacitance at 1 kHz and at
the specified temperature near 30°C, the air-bath temperature. The
measured value is obtained by a comparison to a precision better
than 0.5 ppm with standards whose values are determined andmaintained by periodic calibrations made by NIST.
