浅谈利用测量不确定度对金属紧固件测量结果进行符合性判定

Discussion on using measurement uncertainty to judge the conformity of metal fastener measurement results

符合性判定是根据检测对象的测量结果判断其特定参数是否满足相关标准或规范要求的一种活动,测量不确定度是与测量结果相关联的一个参数,其定量说明了测量结果的质量,表明了被测量值的分散性,是测量结果的组成部分,也是检测结果判定时需要考虑的重要内容。本文以金属紧固件测试为例,浅析如何利用测量不确定度对测量结果进行符合性判定。

Compliance determination is an activity to determine whether the specific parameters of the test object meet the requirements of relevant standards or specifications according to the measurement results of the test object.Measurement uncertainty is a parameter associated with the measurement results,which quantitatively describes the quality of the measurement results and indicates the dispersion of the measured values.It is an integral part of the measurement results and also needs to be considered when determining the test results It is an important part of the project.Taking the metal fastener test as an example,this paper analyzes how to use the measurement uncertainty to determine the conformity of the measurement results.
