摘要/Abstract

摘要：

根据ISO14253-1，研究了基于测量不确定度的产品合格判定原理与方法。分析了产品检验中测量不确定度对合格判定的影响，由不确定度的分布函数推导出批量产品检验中误判率的计算公式；分别讨论了测量结果位于不同区间时,单个产品合格判定及误判率的计算方法；编制了基于LabVIEW的合格判定软件，只需输入相关预知参数，即可获得产品合格判定的结果及其误判率。实例分析表明，测量不确定度造成产品检验存在误判，合格判定软件有效提高了不确定度理论在产品检验应用中的可操作性，基于不确定度的误判率计算为产品供求双方协商确定产品的合格性提供了准确可靠的依据。

Abstract:

According to ISO14253-1, the principles and methods of conformity assessment were studied based on measurement uncertainty. The effects of measurement uncertainty on conformity assessment in product tests were analyzed, and based on the distribution function of measurement uncertainty,formula of misjudgment probability in batch product quality tests was derived; situations for a single product were then discussed when measurement results were in different sections. Software for conformity assessment was designed based on LabVIEW,from which the conformity assessment results and the misjudgment probability could be acquired simply by inputting related parameters.An actual experiment shows that measurement uncertainty may cause misjudgment in product test. Software for conformity assessment can effectively improve the operability of applying uncertainty theory in product tests,and calculation of misjudgment probability based on measurement uncertainty can provide reliable basis for consumer and producer to reach an agreement on the conformity of products.

Key words: product test;conformity , assessment;measurement , uncertainty;misjudgment , probability
