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: 1. On-site calibration service is available for this parameter, 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. 2. Unless otherwise specified, the calibration method/procedure utilized by the client was developed internally.
This Scope of Accreditation, version 012, was last updated on: 06 May 2026 and is valid only when accompanied by the Certificate.
