In this paper,the study of the measurement uncertainty to TFe in K2Cr2O7,and the evaluation to it have been discussed.The source of uncertainty during the experiment has been analyzed in detail.Various parameters has been given quantitative calculation,and a proposal that the collection of each parameter and the statistics of calculation methods should be prepared during the quantitative calculation process.At last,the combining standard uncertainty and the expanding uncertainty have been achieved.The test results have also been reported by the form of uncertainty.
