Re: Expanded Uncertainty vs. Accuracy Requirement
In this case the uncertainty is higher than th accuracy, so it means that your measurement using this device will have a larger uncertainty. That in turn means that the true value of the measurement, expressed at 95% confidence will be the indicated value, plus or minus the uncertainty. Now, the instrument may truly be accurate in its measurements, but when the uncertainty is considered, then all contributions together mean the true value of th measurement may or may not be the indicated value.
I would address this by guardbanding to reduce the effect of the uncertainty on the pass/fail decision.
