Chemical Parameter/Equipment Range CMC2 (±) Comments Gas Detection Equipment – Ethanol Concentration (0 to 0.099) g/210 L (0.100 to 0.500) g/210 L 0.002 g/210 L 1.6 % of reading NIST traceable dry gas ethanol standards, g/210 L is by breath or international equivalent II. Mechanical Parameter/Equipment Range CMC2, 3 (±) Comments Barometric Pressure – Measuring Equipment (550 to 780) mmHg 0.58 % of reading Comparative reference to NIST traceable reference barometer at ambient pressure (740 to 760) mmHg and low pressure (550 to 650) mmHg ____________________ 1 Commercial calibration service is sometimes available for this laboratory.

(A2LA Cert. No. 3384.01) 2/21/2025 Page 2 of 2 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 behavio r of the customer’s device and to influences from the circumstances of the specific calibration. 3 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. 4 This scope meets A2LA’s P112 Flexible Scope Policy.
