(A2LA Cert. No. 3441.01) 06/03/2025 Page 12 of 12 2 Calibration and Measurement Capability Uncertainty (CMC) is the smallest uncertainty of measurement that a laboratory can achieve within its scope of accreditation when performing more or less routine calibrations of nearly ideal measurement standards or nearly ideal measuring equipment. 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, percentages are percent of reading, unless otherwise indicated. 4 Repeatability of the Unit Under Test has not been utilized in the calculation of the CMC value for this measurement parameter. 5 CMC does not include mismatch between the power sensor and device under test. 6 After 24 hours of GPS lock and uninterrupted tracking of 4 or more satellites 7 This scope meets A2LA’s P112 Flexible Scope Policy. 8 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. 9 In the statement of CMC, L is the length in inch/meters; D is the diameter in inch/meters; H is the height in inch/meters. 10 The measurands stated are generated Fluke 5 522A series of instruments. This capability is suitable for the calibration of the devices intended to measure the measurand in the ranges indicated. CMC are expressed as either a specific value that covers the full range or as a fraction of the reading plus a fixed floor specification. (Certain parameters are available as fixed source input values only (e. g. Resistance).
