Calibration and Measurement Capabilities (Expanded Uncertainties) are based on approximately a 95% confidence interval, using a coverage of k=2. 2. This laboratory offers calibration services in its laboratory and on-site at customer-designated locations. 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. 3. Capabilities denoted by an asterisk (*) are performed in the laboratory only and are not available for on-site calibration activity. 4. This scope is formatted as part of a single document including the Certificate of Accreditation No. AC Vice President Version 002 Issued: 03/16/2016 Page 19 of 19
