Standards calibration — Dimensions

Tape measures and test objects used by Measurement Canada inspectors to inspect multiple dimensional measuring devices (MDMDs) are verified for use in the field.


  • Test objects used to inspect MDMDs are measured using instruments traceable to the National Research Council (NRC).
  • Tape measures are verified to meet the tolerances described in Schedule V and/or VI.
  • Measurement Canada's Approval and Calibration Services Laboratory (ACSL) verifies the results and issues a calibration certificate when applicable.

Measurement conditions:

  • Conditions under which standards or test objects are verified vary and are listed on individual calibration certificates.

Calibration location:

  • Test objects and tape measures are sent to a third party for initial assessment.
  • The results are verified by the ACSL in Ottawa, which also issues the calibration certificate.

Fees: N/A

Only standards and test objects used by Measurement Canada inspectors are eligible for this service.
