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.

No. 3237.01) Revised 03/05/2026 Page 20 of 20 3 This laboratory performs field calibration activities for these parameters. 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, percentages are to be read as percent of reading unless otherwise noted. 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. 6 The contributions from the “best existing device” are not included in the CMC claim. 7 The type of instrument or material being calibrated is defined by the parameter. This indicates the laboratory is capable of calibrating instruments that measure or generate the values in the ranges indicated for the listed measurement parameter. 8 This scope meets A2LA’s P112 Flexible Scope Policy. 9 The locations of the laboratories that can perform the calibration are given by a t wo-letter code with valid to dates given in the table below: Location Code Valid to Dates 11500 N Mopac Expressway, Building A Austin, TX 78759-3504 TX January 31, 2028 NI Malaysia Sdn Bhd 8 Lebuh Batu Maung 1 Bayan Lepas 11960 Penang Malaysia MY March 31, 2028 1A Hatar Street Debrecen, Hungary H4031 HU January 31, 2028 2nd Floor, Building 2, No. 400 Fangchun Road, Pudong New District Shanghai, People’s Republic of China 201203 CH January 31, 2028 NI India 81/1 & 82/1, Salarpuria Softzone, Wing B, 5th Floor, Block A, Bellandur, Varthur Hobli, Bengaluru, Karnataka Bengaluru, India IN January 31, 2028 Click here to return to page 1
