(A2LA Cert. No. 5098.01) 03/27/2025 Page 11 of 11 2 Calibration and Measurement Capability Uncertainty (C MC) 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 ca libration. Please note the uncertainties achievable on a customer's site can normally be expected to be la rger than the Calibration and Measurement Capability uncertainty (CMC) that the accredited laboratory has been assigned on the A2LA Scope. Allowance must be made for aspects such as the environment at th e 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 calibration uncertainty being larger than the CMC uncertainty. 4 This scope meets A2LA’s P112 Flexible Scope Policy. 5 The stated measured values are determined usi ng 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. CMCs 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 type of instrument or material being calibra ted 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. 7 In the statement of CMC, percentages are percentages of reading, unless otherwise indicated.

For the calibrations to which this accreditation applies, please refer to the laboratory’s Calibration Scope of Accreditation. Accredited Laboratory A2LA has accredited TRIN CALSERVICES INC. Brampton, Ontario, CANADA for technical competence in the field of Calibration This laboratory is accredited in accordance with the recognized International Standard ISO/IEC 17025:2017 General requirements for the competence of testing and calibration laboratories. This laboratory also meets the requirements of R205 – Specific Requirements: Calibration Laboratory Accreditation Program. This accreditation demonstrates technical competence for a defined scope and the operation of a laboratory quality management system (refer to joint ISO-ILAC-IAF Communiqué dated April 2017).
