21 1 This laboratory offers commercial calibration, dimensional testing and field calibration service. 2 Calibration and Measurement Capability (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 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 Where ranges are not specified, the CMC stated is for the cardinal points only. 5 In the statement of CMC, R is the numerical value of the resolution of the device. In the statement of CMC, L is the numerical value of the nominal length of the device measured in inches. In the statement of CMC, adjustable thread rings are set to applicable specifications using calibrated master set plug gages. In the statement of CMC, percentages are percent of reading, unless otherwise indicated. 6 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. 7 This laboratory meets R205 Specific Requirements: Calibration Laboratory Accreditation Program for the types of dimensional tests listed above and is considered equivalent to that of a calibration.
