摘要
对EDTA滴定法测定工业锅炉给水总硬度的测量过程进行不确定度评定。充分考虑测量重复性、标准溶液的配制、滴定等过程对测量的影响,计算水中总硬度测量的相对合成标准不确定度为1.01×10-2。
The uncertain degree that measurement of total hardness of feedwater for industry boiler by EDTA titration law was evaluated. The influencing factors as the repetitiveness, confection of standard solution, the titration etc for measurement were considered fully. The relative combined standard uncertainty that measurement of feedwater total hardness be calculated was 1.01×10^-2.
