1The uncertainty covered by the Calibration and Measurement Capability (CMC) is expressed as the expanded
uncertainty having a coverage probability of approximately 95 %. It is the smallest measurement uncertainty that a
laboratory can achieve within its scope of accreditation when performing calibrations of a best existing device. The
measurement uncertainty reported on a calibration certificate may be greater than that provided in the CMC due to the
behavior of the calibration item and other factors that may contribute to the uncertainty of a specific calibration.
2When uncertainty is stated in relative terms (such as percent, a multiplier expressed as a decimal fraction or in scientific
notation), it is in relation to instrument reading or instrument output, as appropriate, unless otherwise indicated.

Note
ppm = parts per million
