CMCs represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually using a coverage factor of k = 2. The actual measurement uncertainty of a specific calibration performed by the laboratory may be greater than the CMC due to the behavior of the customer’s device and to influences from the circumstances of the specific calibration. 3 This scope meets A2LA’s P112 Flexible Scope Policy.

Ranges are reproduced from the accredited scope document as published, and only where we found that range printed in the document for the line. Otherwise the cell reads “See scope document”. An absent range means the register did not state one. Line numbers are ours, for cross-reference; they follow the order of the scope document.
