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 The stated measured values are determined using the indicated instrument (see Comments). This capability is suitable for the calibration of the devices intended to measure or generate the measured value in the ranges indicated. CMCs are expressed as eithe r a specific value that covers the full range or as a fraction/percentage of the reading plus a fixed floor specification. 4 In the statement of CMC, percent refers to a percent of reading unless otherwise noted. 5 The type of instrument or material being calibrated is defined by the parameter. This indicates the laboratory is capable of calibrating instruments that measure or generate the values in the ranges indicated for the listed measurement parameter. 6 This scope meets A2LA’s P112 Flexible Scope Policy.
