- ¹ The 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.
- ² When uncertainty is stated in relative terms (percent, multiplier, decimal fraction, or scientific notation), it is in relation to instrument reading or instrument output, as appropriate, unless otherwise indicated.
- ³ Capability is suitable for the calibration of measuring devices in the stated ranges.
- ⁴ Capability is suitable for the calibration of devices intended to generate the indicated quantity in the stated ranges.
- ⁵ Also available as site calibration. Note that actual measurement uncertainties achievable at a customer's site can normally be expected to be larger than the uncertainties listed on this Scope of Accreditation.
Measurements are delivered within a 95% confidence level (k=2) with full 'As Found – As Left' data on certificates where applicable.
