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 behavior of t he customer’s device and to influences from the circumstances of the specific calibration. 3 In the statement of CMC, R is the numerical value of the resolution of the device in micro inches, L is the measurement of length. 4 This scope meets A2LA’s P112 Flexible Scope Policy.
