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 CMCs are expressed as either a specific value that covers the full range or as a fraction of the reading plus a fixed floor specification. 4 CMCs for Vibration parameters are for Sensitivity (accelerometers/sensors) or Acceleration level (shakers). 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. 7 In the statement of range, f is frequency.
