Abstract:In order to improve the reliability of inspection results of batch products reasonably and reduce the influence of measurement uncertainty on product qualification, the problem of product misjudgment rate in full inspection is studied, and the quantitative formula of product quality misjudgment risk is derived. This paper analyzes two kinds of misjudgment in product inspection and the conditions of misjudgment, and studies the calculation formula of misjudgment rate for different misjudgment. The results show that the proposed quantitative model can comprehensively reflect the risk of misjudgment in product inspection caused by measurement uncertainty, and the quantitative data can more directly reflect the risk for both producers and consumers, thus promoting inspectors to judge the product qualification more carefully.
