Best Measurement Uncertainties (Expanded Uncertainty) are based on approximately a 95% confidence interval, using a coverage of k=2 2. The uncertainty associated when calibrating a balance/scale is dependent on local conditions, such as the resolution of the unit being calibrated and the environment in which the balance/scale is operating. The uncertainty listed in the scope here represents the best uncertainty for a balance/scale which the organization typically calibrates in its lab. Since field (on-site) conditions are typically more variable than those in the laboratory, larger measurement uncertainties are expected in the field (on-site) than what is reported on the accredited scope. 3. Uncertainties do not include inaccuracies due to sensor mismatch. 4. On site capability for this parameter using plug gage comparator only. Gages up to 4 inches. 5. For uncertainties expressed as b + ml, L = Length in inches. 6. For uncertainties expressed as b + md, D = Diameter or Diagonal in inches. 7. Where ranges overlap, the uncertainty for the overlapping specifications will be the lower of the two uncertainties. 8. On site capability offered for this parameter. Since field (on-site) conditions are typically more variable than those in the laboratory, larger measurement uncertainties are expected in the field (on-site) than what is reported on the accredited scope. 9. This scope is part of and must be included with the Certificate of Accreditation No. AC-1272 President/CEO Page 20 of 20
