1 This laboratory offers commercial and field calibration service.
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 standards or nearly ideal measuring equipment. CMCs represent
expanded uncertainties expressed at approximately the 95 % level of confidence, usually using a coverage
factor of k = 2. The actual measurement uncertainty of a specific calibration performed by the laboratory
may be greater than the CMC due to the behavio r of the customer’s device and to influences from the
circumstances of the specific calibration. | ||

3 Field calibration service is available for this calibration. Please note the actual measurement uncertainties
achievable on a customer's site can normally be expected to be larger than the Calibration and
Measurement Capability Uncertainty (CMC) found on the A2LA Scope. Allowance must be made for
aspects such as the environment at the place of calibration and for other possible adverse effects such as
those caused by transportation of the calibration equipment. The usual allowance for the uncertainty
introduced by the item being calibrated, (e.g. resolution) must also be considered and this, on its own,
could result in the actual measurement uncertainty achievable on a customer’s site being larger than the
CMC.

Ranges are reproduced from the accredited scope document as published, and only where we found that range printed in the document for the line. Otherwise the cell reads “See scope document”. An absent range means the register did not state one. Line numbers are ours, for cross-reference; they follow the order of the scope document.
