氯化铁含量测定不确定度评定
Uncertainty Evaluation of Measurement on Ferric Chloride Content
-
摘要: 对净水剂氯化铁中氯化铁含量的测定进行不确定度的评定,建立不确定度评定程序和方法。依据《测量不确定度评定与表示指南》建立数学模型,进行不确定度的计算并合成不确定度。找出影响净水剂氯化铁中氯化铁含量测定的主要因素,分析归纳了不确定度分量的主要来源,并对结果予以讨论。评定程序和方法符合规范要求,适用于同类型试验不确定度评定。Abstract: Uncertainty of ferric chloride content as purifier was evaluated,and assessment procedures,mathematical modelling and method were established.Uncertainty was computed and synthesized.Primary factors that influenced ferric chloride content determination were found;primary sources of the uncertainty weight were analyzed and induced.Assessment procedures and methods conformed regulatory requirements,applied to the same type of experimental uncertainty evaluation.
