采用实验室间量值比对的方法开展能力验证。将主导实验室提供的传递标准逐一传递到各实验室进行计量检测,通过对其测量不确定度的评定,获得其合成标准不确定度及扩展测量不确定度,采取各参比实验室间测量结果与其不确定度的一致性用归一化偏差E_n进行评价的方法,获得比对结果能力验证是否满意的评价。 The use of inter-laboratory methods to measure the value of proficiency testing. The delivery standards provided by the leading laboratory will be passed one by one to the laboratories for measurement and measurement. The uncertainty of the measurement standard will be obtained through the evaluation of the measurement uncertainty, and the uncertainty of the synthesis standard and the expansion of measurement uncertainty will be obtained. Results and its consistency of uncertainty with the normalized deviation E_n evaluation method to obtain the ability to verify the results of the comparison is satisfied with the evaluation.
