耳标结合力测量的不确定度评定

Uncertainty Evaluation of the Measurement to Ear Tag Binding Force

为全面评价耳标结合力测量指标,分析耳标在结合力检测中的不确定度来源,对单次测量引起的不确定度分量进行不确定度评定,根据方差合成定理,合成标准不确定度,并计算扩展不确定度,给出结合力测量不确定度报告,完善耳标结合力单次测量结果的评定,为标准修订提供有效的参考值。

In order to evaluate comprehensively the index of ear tag binding force,sources of uncertainty in an ear tag binding detection are analyzed,components of uncertainty on the single measurement are evaluated.According to the variance composition theorem,the combined standard uncertainty and expanded uncertainty are calculated,measurement uncertainty report is given,the evaluation of single measurement on ear tag binding force is improved and the effective reference is provided for standard revision.
