Analysis of Measurement Process Characteristics Based on Measurement Uncertainty

Abstract

In order to reasonably evaluate the measurement process, the qualified probability and misjudgment risk caused by measurement uncertainty and their impact should be analyzed. The accurate values and calculation examples of qualified probability under different measurement capability indexes are given, which can provide reference for the compliance judgment of measurement process. The calculation results show that when the measurement results are near the upper and lower limits of conformance interval, the probability of misjudgment increases, and corrective action should be taken to reduce the risk to meet the measurement requirements.
