引伸计系统示值校准不确定度评定

Evaluation of Uncertainty in Indication Calibration of Extensometer System

依据JJG 762-2007《引伸计》检定规程,使用引伸计标定器校准YYU-10/50型引伸计的系统示值,参照JJF 1059.1-2012《测量不确定度评定与表示》计量技术规范,分析了系统示值结果不确定度的来源,并进行了综合评定。

According to the verification regulation for extensometer of JJG 762-2007,the system indication value of YYU-10/50 extensometer is calibrated by calibrator of extensometer.Refer to the evaluation and expression of uncertainty in measurement of JJF 1059.1-2012,the source of uncertainty of indication result of the system is analyzed,and the comprehensive evaluation is finished.
