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 standard s or nearly ideal measuring equipment. CMC’s
represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually using
a coverage factor of k = 2. The actual measurement uncertain ty 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 This scope meets A2LA’s P112 Flexible Scope Policy.
4 The type of instrument or material being calibra ted 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. | ||
