在ISO/IEC 17025-1999中要求检测实验室具有评价测量不确定度的程序,能够对检测项目的不确定度作出正确评估,满足客户及监测工作的要求。测量不确定度在实验室数据比对,方法确认、标准设备校准、量值溯源及实验室质量控制与管理等方面具有重要的意义。我们根据《测量不确定度评
In ISO / IEC 17025-1999, testing laboratories are required to evaluate the uncertainty of measurement procedures, which can correctly assess the uncertainty of test items and meet the requirements of customers and monitoring work. Measurement uncertainty is of great significance in laboratory data alignment, method validation, standard equipment calibration, traceability and laboratory quality control and management. We based on "measurement uncertainty evaluation
