(A2LA Cert. No. 4111.02) 8/26/2025 Page 5 of 5 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. 4 In the statement of CMC, L is the numerical value of the nominal length of the device measured in millimeters (metric units) or inches (imperial units); D is the numerical value of the nominal diameter of the device measured in millimeters (metric units) or inches (imperial units) ; and A is the nominal numerical value of an angle measured in decimal degrees. 5 This scope meets A2LA’s P112 Flexible Scope Policy. 6 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. 7 Repeatability of the Unit Under Test has not been utilized in the calculation of the CMC value for this measurement parameter.
