Precision Measuring

(A2LA Cert. No. 1768.01) 8/22/2025 Page 4 of 4 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. 4 In the statement of CMC, for linear measurements; L is the nominal length of the device in inches, except where noted. For straightness and squareness measurements, S is the straightness error in micro-inches; F is the distance the optics travel during test in feet. With angle measurements, B is the measured error in arc-seconds, and M is the distance the optics travel during test in meter s. With flatness measurements, D is the diagonal length of the surface plate. 5 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. 6 CMC performance is identified as 3D (X-Y-Z) for measurements performed with the Faro Laser Tracker and Hexagon Articulating Arm CMM in the stated machine volume of the X, Y and Z coordinate ranges; or in the case of 2D non-contact measurements, the area of X and Y coordinates. 7 3D (X-Y-Z) length measurement performance is within the stated X, Y and Z coordinate ranges based on ball bar test data. 8 This scope meets A2LA’s P112 Flexible Scope Policy.
