摘要
In this paper, the authors describe the rational assessment of the uncertainty component in the testing process, analyse and calculate the standard and composited uncertainty of various components. According to the composited standard uncertainty, the authors obtain the extended uncertainty of testing result and the final result formulae: (14.8±0.50) μg/g.
