This laboratory offers commercial calibration services, dimensional testing, and field calibration services.

2Calibration and Measurement Capability Uncertainty (CMC) is the smallest uncertainty of measurementthat 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 coveragefactor 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 thecircumstances 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 CMC found on the A2LA
Scope. Allowance must be made for aspects such as the environment at the place of calibration and forother 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) mustalso be considered and this, on its own, could result in the actual measurement uncertainty achievable ona customer’s site being larger than the CMC.

4This laboratory meets A2LA R205- Specific Requirements: Calibration Laboratory Accreditation
Program for the types of dimensional tests listed above and is considered equivalent to that of acalibration.

5This scope meets A2LA’s P112 Flexible Scope Policy.
