Electrical Standards - Calibration Services

Ordering Calibrations Services

The Electrical Standards Group develops and maintains Canada's national standards of electrical measurement and disseminates the corresponding electrical units throughout Canada. The Group provides technical support to the Canadian Laboratory Assessment Service (CLAS) in the area of electrical standards and participates with other national and international organizations in activities related to electrical standards.

Contact: Dr. Dave Inglis
Tel. 613-991-5650

The calibration services of the Group cover:

DC resistance from 10 µto 100 T
DC voltage from 100 µV to 100 kV
AC voltage (ac-dc difference) from 0.5 V to 500 V and 2 Hz to 500 MHz*
AC resistance (shunts) from 25 mto 100from dc to 5 kHz*
AC capacitance from 0.001pF to 1 µF at 1 kHz
AC inductance from 1 µH to 10 H at 1 kHz
RF voltage (ac-dc difference) from 1 µV to 100 V and from 1 MHz to 1 GHz*
RF impedance (Z/Zo) from 0.5 to 2.0 from 250 MHz to 18 GHz
RF attenuation to 60 dB at frequencies from 1 MHz to 36 GHz
RF power from 1 µW to 10 mW from 1 MHz to 40 GHz
*not all combinations are available

A number of other measurements can be performed by special arrangement.

The Electrical Standards Group usually begins calibrations only in April, May, June, October, November, and December. Calibrations may begin in other months, but only by special arrangement. To assure minimum calibration delays, please consult with the Group before sending calibration equipment to NRC. Measurements are normally performed at room temperature, typically 20°C to 23°C, and approximately 40% relative humidity, unless otherwise specified.

Standard cells normally require from one to three weeks to stabilize under laboratory conditions of constant temperature followed by a period of about two weeks for calibration. The calibration report will quote the mean value of the electromotive force (emf) observed during this latter period, in terms of the unit of emf maintained by NRC, and will provide an indication of the variations observed. If appreciable, the change observed during the initial stabilizing period will also be reported.
