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 The measurands stated are measured with the Fluke 8508A. This capability is suitable for the calibration of the parameters indicated. CMCs are expressed as either a specific value that covers the full range or as a combination of the fraction/percent of the reading/output plus a range specification. 4 In the statement of CMC, percentages are to be read as percent of reading unless otherwise noted. 5 CMC is defined at 1 kHz only. The laboratory implements the IET Uncertainty calculator for intermediate values and frequencies. 6 CMC is defined at 1 kHz only. The laboratory implements the IET Uncertainty calculator for intermediate values and frequencies which utilizes the “AH2700a Complete Specifications in Excel” spreadsheet from Andeen-Hagerling. 7 This laboratory meets A2LA’s P112 Flexible Scope Policy. 8 The type of instrument or material being calibra ted is defined by the parameter. This indicates the laboratory is capable of calibrating instruments that measure or generate the values in the ranges indicated for the listed measurement parameter

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.
