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. 3 Field calibration service is available for this calibration and this laboratory meets A2LA R104 General Requirements: Accreditation of Field Testing and Field Calibration Laboratories for these calibrations. 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. 4 In the statement of CMC, L is the numerical value of the nominal length of the device measured in millimeters. (A2LA Cert. No. 3512.12) 01/26/2018 Page 14 of 15

5 The stated measured values are determined using the indicated instrument (see Comments). This capability is suitable for the calibration of the devices intended to measure or generate the measured value in the ranges indicated. CMC s are expressed as either a specific value that covers the full range or as a percent or fraction of the reading plus a fixed floor specification. (A2LA Cert.
