No. 3677.01) 7/21/2025 Page 1 of 1 SCOPE OF ACCREDITATION TO ISO/IEC 17025:2017 TEXAS GAUGE & CONTROLS 7575 Dillon Street Houston, TX 77061 Michael Hamilton Phone: 713 641 2282 CALIBRATION Valid To: June 30, 2027 Certificate Number: 3677.01 In recognition of the successful completion of the A2LA evaluation process (including an assessment of the organization’s compliance with R205 – A2LA’s Calibration Program Requirements), accreditation is granted to this laboratory to perform the following calibrations 1, 4: I. Mechanical Parameter/Equipment Range CMC2, 3, 5 (±) Comments Pressure – Generate/Measure (3000 to 30 000) psi (18) psi ADDITEL 686 _________________________ 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 In the statement of CMC, P represents the pressure measured in psi. 4 This scope meets A2LA’s P112 Flexible Scope policy. 5 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.
