摘要
本文依据GB/T 176-2008《水泥化学分析方法》硫酸钡重量法基准法测量水泥的三氧化硫含量,分析了操作要点,并依据JJF 1059.1-2012《测量不确定度评定与表示》和CNAS-GL06《化学分析中不确定度的评估指南》,对硫酸钡重量法测量水泥中三氧化硫含量的不确定度进行评定。
According to the barium sulphate gravimetry method which is described in GB / T 176- 2008 ＂Methods for Chemical Analysis of Cement＂for chemical analysis of sulfur trioxide content of cement,the operating procedure is analyzed. And according to JJF 1059. 1-2012 ＂Evaluation and Expression of Uncertainty in Measurement＂and CNAS- GL06＂Guidance on Evaluating the Uncertainty in Chemical Analysis＂,the uncertainty in measurement of the barium sulphate gravimetry method for chemical analysis of sulfur trioxide content of cement is evaluated.
