摘要
无损检测在化工设备检测过程中起着重要作用,确认无损检测结果的置信度,可以进一步提高化工设备安全性。本文介绍了纵波探伤的不确定度评定方法,测定其置信概率p=95%时,t分布值为1.96,扩展不确定度U95为1.3d B。
Nondestructive Testing（ NDT） plays an important role in chemical equipment testing. Confirming the confidence level of NDT could improve the security of chemical equipment. Evalauation of uncertainty in longitudinal wave testing was introduced. When confidence interval p = 95%,value of distribution t was 1. 96,overall uncertainty U95 was 1. 3d B.
