测量不确定度定义为表征合理地赋予被测量之值的分散性[1]。在ISO/IEC17025-1999中要求检测实验室具有评价不确定度的程序,能够对测量项目的不确定度做出正确的评估,满足客户及监测工作的要求。在这种情况下,实验室应努力找出不确定的所有分量且做出合理评定,确保检验结果不确定度已知度符合要求。%Characterization of measurement uncertainty is defined as reasonable given the value of the measured dispersion [1]. In the ISO / IEC 17025-1999 requested the testing laboratory with the evaluation of uncertainty of the procedures to the uncertainty of the measurements to make the right assessment, and monitoring work to meet customer requirements. In this case, the laboratory should try to identify all the components of uncertainty and make a reasonable assessment to ensure that the test results are known degree of uncertainty to meet the requirements.
