(A2LA Cert. No. 7355.01) 9/26/2024 Page 1 of 1 SCOPE OF ACCREDITATION TO ISO 17025:2017 TEXAS AEROSPACE TECHNOLOGIES 7801 Mesquite Bend Drive, Suite 101 Irving, TX, 75063 Mike Sutphin Phone: 903 257 5131 CALIBRATION Valid To: October 31, 2026 Certificate Number: 7355.01 In recognition of the successful completion of the A2LA evaluation process (including an assessment of the organization’s compliance with A2LA’s Calibration Program Requirements), accreditation is granted to this laboratory to perform the following calibrations 1, 3: I. Mechanical Parameter/Equipment Range CMC2 (±) Comments Pressure Transducers (0 to 38) inHg (29 to 103.5) inHg 0.0022 inHg 0.0084 inHg DMA PAMB11H test standard __________________________________________________________ 1 This laboratory offers commercial calibration service. 2 Calibration and Measurement Capability Uncertainty (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 This scope meets A2LA’s P112 Flexible Scope Policy.
