摘　　要：测量不确定度的计算是检测校准活动的基础,直接影响合格评定的结果。也是《检测和校准实验室能力通用要求》(CNAS-CL01)对测量结果的计量溯源性的基本要求之一。该文介绍了测量不确定度的评定GUM法以及在汽车实验室的应用,说明了测量不确定度在符合性判定中的应用,针对临界值给出了一些判定处理方法,也说明了测量不确定度在测量设备选用上的作用。The calculation of measurement uncertainty is the basis of testing and calibration activities,which directly affects the results of conformity assessment.It is also one of the basic requirements for metrological traceability of measurement results in CNAS-CLO1“General Requirements for Testing and Calibration Laboratory Capabilities"”.This paper introduces the evaluation method of measurement uncertainty(GUM)and its application in vehicle laboratory,expounds the application of measurement uncertainty in the determination of conformity,gives some methods for the critical value,and explains the role of measurement uncertainty in the selection of measuring equipment.
