| SCC accreditation (ISO/IEC 17025) |
|
This CLAS Certificate is published by the CLAS program of the National Research Council of Canada (NRC) in cooperation with the laboratory accreditation program of the Standards Council of Canada (SCC), Canada's accreditation body for calibration and testing laboratories. The SCC accredits the capability of the named laboratory for being able to perform calibrations as per the listed Calibration and Measurement Capabilities with metrological traceability to the International System of Units (SI) or to standards acceptable to the CLAS program. See supplementary notes.
