The uncertainty covered by the CMC is the expanded uncertainty with a coverage probability of approximately 95 %. The value expressed as a percentage is a relative measurement uncertainty and refers to a percentage contribution in the value of the measurand. In other cases, CMC is expressed in measurand units.
