1 This laboratory offers commercial dimensional testing/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 nea rly 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 behavior of the customer’s device
and to influences from the circumstances of the specific calibration. | to 750 mm |

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 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 actual 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.
