Laboratories interested to have calibration results for mass standards recognized for the certification of the standards by Measurement Canada pursuant to the Weights and Measures Act must inform the National Research Council (NRC) at the time of their Calibration Laboratory Assessment Service (CLAS) Certification Process by checking the appropriate box when submitting their application form for CLAS Certification and SCC Accreditation.

For existing CLAS Laboratories, an expansion of scope application for CLAS Certification and SCC Accreditation form must be submitted to the NRC in order to include this type of calibration in their scope and to obtain the appropriate traceability of their reference standards.
