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 measurement performed by the laboratory may be greater than the CMC due to the behavior of the customer’s device and to influences from the circumstances of the specific measurement. 3 In the statement of CMC, L represents the numerical value of the nominal length of the device measured in inches. 4 This test is not equivalent to that of a calibration. 5 This scope meets A2LA’s P112 Flexible Scope Policy.
