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. Laboratory offers calibration services at the laboratory's own facilities and at the client or other agreed upon facilities. 2. On-site calibration service is offered for these parameters. 3. This scope is formatted as part of a single document including Certificate of Accreditation No. L1114-1. Page 8 of 8
