0.01级交流数字功率表标准装置不确定度的评定

Evaluation of Uncertainty on 0.01 Class Standard Equipment of AC Digital Power Meter

在 ISO/IEC导则 2 5《校准和检测实验室能力的通用要求》指明 ,校准实验室出具的每一份证书或报告 ,均应包括有关测量结果不确定度的说明。根据要求 。

In the ISO/IEC, the item 25, the 《General Requirement for the Competence of Calibration and Testing Laboratories》that every certificate or report from calibration laboratory must include the explanation of uncertainty of relevant measurement. According to the requirement, through example of evaluating the measurement uncertainty for AC digital power-meter, its method and process are explained.
