本文根据国家计量技术规范JJF 1 059.1—2012《测量不确定度评定与表示》,依据GB/T1 0545—2007《白酒分析方法》中总酸的测定方法,对白酒中总酸含量的不确定度评定。目的真实反映白酒中总酸检测结果的精确度,评定总酸检测的不确定度。方法分析不确定度的来源,通过计算给出不确定度。结果相对扩展不确定度为0.006 g/L。结论各不确定度分量之间相差不大,对合成不确定度都有贡献,在不确定度评定中均应考虑。
According to the National Measurement Specifications JJF 1 059.1-2012 Assessment and Expression of Uncertainty in Measurement, according to the determination method of total acid in GB / T1 0545-2007 Liquor Analysis Method, the uncertainty of total acid content in liquor assessment. Objective To truly reflect the accuracy of total acid test results in liquor and evaluate the uncertainty of total acid test. Method to analyze the source of uncertainty, given by the calculation of uncertainty. The relative expansion uncertainty of the result is 0.006 g / L. Conclusion There is not much difference between the components of uncertainty, which contributes to the uncertainty of synthesis. Both of them should be considered in the evaluation of uncertainty.
