SCC Accreditation: (ISO/IEC 17025)

  • Accredited Laboratory 810
  • First issued
  • Issue 1.0e

This scope of calibration capabilities is published by the CLAS program of the National Research Council of Canada (NRC) in close co-operation 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 the listed calibrations at the given Calibration Measurement Capability (see Supplementary note C and note D) with traceability to the International System of Units (SI) or to standards acceptable to the CLAS program.
