测量不确定度的评定及其在检测实验室中的应用

Evaluation and application in the testing laboratory of measurement uncertainty

介绍了测量不确定度的发展和定义,分析了测量不确定度与测量误差的区别,并结合混凝土芯样抗压强度测量不确定度评定实例,阐述检测实验室测量不确定度评定的一般流程,为检测实验室的检测结果不确定度评定提供有益的参考。

Development and definition of measurement uncertainty are introduced, and the differences between the measurement uncertainty and measurement error are analyzed. Combining with an example of measurement uncertainty evaluation of concrete core samples compressive strength, the general process of measurement uncertainty evaluation in testing laboratory are clarified in this paper, in order to provide some useful references to the test results in testing laboratory.
