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.
- Conditions under which standards or test objects are verified vary and are listed on individual calibration certificates.
- 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.
Only standards and test objects used by Measurement Canada inspectors are eligible for this service.
ISO/IEC 17025 accreditation
Many of the calibration services offered by Measurement Canada's Approval and Calibration Services Laboratory (ACSL) are accredited to international standard ISO/IEC17025—General Requirements for the Competence of Testing and Calibration Laboratories. This accreditation is granted by the Standards Council of Canada, Canada's accreditation body for calibration and testing laboratories via the Calibration Laboratory Assessment Service (CLAS) program of the National Research Council of Canada. Measurement Canada's ACSL is accredited to perform calibrations listed on its CLAS certificate, number 2009-03. All accredited calibrations are traceable to the International System of Units or to standards acceptable to the CLAS program. The certificate of calibration and designation created by Measurement Canada for each calibration of a standard that falls under this scope bears the CLAS logo.
The ISO/IEC 17025 standard requires that certain information be reported on the certificates issued for calibrations by accredited laboratories or be made available to clients if they request it. In its role as a regulator, Measurement Canada chooses what information is relevant to report on the certificates that it issues for calibrations. The ACSL keeps any information not presented on the certificate, but required under ISO/IEC 17025, and makes it available to its clients upon request. In accordance with Government of Canada privacy policies, this information is only provided to the requestor of the calibration service for the certificate in question. To request this information, add a comment on the Calibration Services Request form or contact the ACSL.
