Thermodynamics Parameter/Equipment Range CMC2, 8 (±) Comments Temperature – Measure & Measuring Equipment (0 to 30) °C (21 to 25) °C 0.009 °C 0.01 °C AM1760 secondary SPRT RTD-002 ___________________________ 1 This laboratory offers commercial calibration service. 2 Calibration and Measurement Capability (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. Calibration and Measurement Capabilities 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 Expressed as linear error of reported Cal Factor, reported in percentage, where the ideal Cal Factor is 100 %. Number given is the CMC of the highest uncertainty test in the frequency range. 4 The CMC claim is smaller than that of the expanded uncertainty claim for NIST as listed in the BIPM Key Comparison Database. A2LA has evaluated the laboratory’s CMC claim and has verified this information to be correct and appropriate. 5 In the statement of CMC, percentages are percentage of reading, unless otherwise indicated. 6 This scope meets A2LA’s P112 Flexible Scope Policy. 7 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. 8 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.
