Accreditation scope — calibration items (13)

CMC — lowest stated expanded measurement uncertainty (ILAC-P14, EA-4/02 M); if not stated otherwise, coverage probability approx. 95 % and values without a unit are relative to the measured value. The uncertainty of a specific calibration may be higher.
