CMCs represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually using a coverage factor of k = 2. The actual measurement uncertainty of a specific calibration performed by the laboratory may be greater than the CMC due to the behavio r of the customer’s device and to influences from the circumstances of the specific calibration. 3 In the statement of CMC percent is defined as the percentage of the reading. 4 This scope meets A2LA’s P112 Flexible Scope Policy.
