Calibration and Measurement Capability (CMC) is expressed in terms of the measurement parameter, measurement range, expanded uncertainty of measurement and reference standard, method, and/or equipment. The expanded uncertainty of measurement is expressed as the standard uncertainty of the measurement multiplied by a coverage factor of 2 (k=2), corresponding to a confidence level of approximately 95%.
Notes:
- Mobile and On-site calibration service is available for most parameters, since on-site conditions are typically more variable than those in the laboratory, larger
measurement uncertainties are expected on-site than what is reported on the accredited scope. Marsh Mobile Lab environmental conditions are controlled to meet the
conditions needed to achieve the uncertainties listed in the Calibration and Measurement Capability (CMC) of the laboratory. - These parameters can only be performed at the laboratory’s fixed location.
- X = measured value, F = measured value in lbf, L = Length in inches.
- This scope is formatted as part of a single document including Certificate of Accreditation No. AC-1172.
