Accreditation scope — calibration items (3)

The uncertainty covered by the CMC does not include the uncertainty components related to the stability and homogeneity of the reference material. The measurement uncertainty value for CMC expressed as a percentage is a relative measurement uncertainty and refers to a percentage contribution in the value of the measurand.
