Calibration and Measurement Capability Uncertainty (CMC) is the smallest uncertainty of measurementthat 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 coveragefactor 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 thecircumstances of the specific calibration.

3

This scope meets A2LA’s P112 Flexible Scope Policy.

4

The type of instrument or material being calibrated is defined by the parameter. This indicates thelaboratory is capable of calibrating instruments that measure or generate the values in the ranges indicatedfor the listed measurement parameter.
