1The uncertainty covered by the Calibration and Measurement Capability (CMC) is expressed as the expanded uncertainty having a specific coverage probability of approximately 95 %. It is the smallest measurement uncertainty 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. The actual measurement uncertainty of a specific calibration performed by the laboratory may be greater than that provided in the CMC due to the behavior of the customer’s device and to influences from the circumstances of the specific calibration.
2If information in this CMC is presented in non-SI units, the conversion factors stated in NIST Special Publication 811 “Guide for the Use of the International System of Units (SI)” apply.
3When 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.
4Capability is suitable for the calibration of measuring devices in the stated ranges.
5Capability is suitable for the calibration of devices intended to generate the measurand in the stated ranges.
6The contamination leak test is performed as part of the calibration of nuclear density gauges, and is not considered a calibration in itself, but is listed here for completeness. The stated uncertainty is based on the repeatability of the test only.
