    The verification procedures in this document tests to the 90-day, 99 % confidence specification limits of the 5560A. For the 5550A and 5540A or for other calibration intervals, you must calculate limits based upon the specification that was selected. The subsequent examples show how the 1-year specification limits are calculated.

    These must be accounted for their individual situations, so it is not possible for Fluke Calibration to estimate uncertainty for all user calibrations. Those doing the calibration of the Product can verify to 99 % confidence limits, 95 % confidence limits, 90-day, 1-year specifications, or 2-year specifications.

Two of these rules are shown as examples to develop test limits through guardbanding. ILAC G8 (ISO 14253-1) Decision Rule In this guardband strategy example, determine the test limit by the subtracting the uncertainty of the measurement from the specification.
