文章阐述了按照GB/T601-2002标准规定的方法标定氢氧化钠标准溶液,按照JJF1059-2012标准规定的方法对其进行测量不确定度评定,分析了氢氧化钠标准溶液标定的不确定度主要来源,通过数学模型对各不确定度分量进行评定,结果表明氢氧化钠标准溶液的浓度为0.09927±0.00026mol/L(K=2)。
This paper describes the standard solution of sodium hydroxide according to GB / T 601-2002 standard calibration method, in accordance with the method of JJF1059-2012 standard measurement uncertainty evaluation of the analysis of the sodium hydroxide standard solution of the uncertainty of the main Sources, through the mathematical model to evaluate the components of uncertainty, the results show that the concentration of sodium hydroxide standard solution 0.09927 ± 0.00026mol / L (K = 2).
