摘要
通过对应用GB/T5687.2-2008《铬铁和硅铬合金铬含量的测定过硫酸铵氧化滴定法和电位滴定法》(可视法)测定铬铁中铬含量的不确定度的系统分析,找出了影响该方法测量结果不确定度的主要来源,为控制检测质量提供了理论依据。
According to the system analysis of determination of indeterminacy assessment of chrome content in ferrochrome by the application of GB/T5687.2-2008 Chrome content determination of ammonium persulfate oxidation titration and potential titration method of ferrochrome and silicon chromium alloy(Visual method),finding the main source of affecting measuring result indeterminacy,offering theoretical basis for controlling detection quality
