Objective To use measurement uncertainty evaluation for the characterization of reasonably measuring the dispersion, to understand the scope of the measuring results using quality control chart analysis for the main factors influencing the measurement results, and thus to minimize the measurement error. Methods GB/T 5413.3 2010 “national food safety standards on the determination of fat in infant food and dairy”No.1 method was applied. Results Using pure milk samples of Check sample (CS) to check the sample, in which the sample verification refers to the quality control measurement with reference materials for the detection value to specify the lab testing samples. During precision measurement conditions, the fat in milk detection was measured by uncertainty evaluation. Conclusion The uncertainty evaluation method in the analysis of laboratory quality control work has a strong practical value.
