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 the customer s device and to influences from the circumstances of the specific calibration. 3 In the statement of CMC, CF stands for calibration factor. 4 In the statement of CMC, percentage are percentages of reading. 5 This accreditation covers testing performed at the main laboratory, and the satellite location West Building Metrology Laboratory. 6 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. CMC s are expressed as either a specific value that covers the full range or as a percent or fraction of the reading plus a fixed floor specification. 7 In the statement of CMC, VSWR refers to Voltage Standing Wave Ratio.
