摘要
对用GB/T 35 5 8- 1996《煤中氯的测定方法》中高温燃烧水解 -电位滴定法测定煤中氯含量测定结果的不确定度进行了评定。通过对影响测定结果的不确定度分量的分析和量化 ,求得煤中氯含量测定结果的扩展不确定度为 0 .0 0 3%。
The uncentainty of measurement was evaluated for the determination of chlorine in coal by the method of GB/T 3558-1996, the high temperature combustion hydrolysis-potentionmetric titration method. By analyzing and quantifying the uncertainty components of the measurement results, the expanded uncertainty of measurement result of chlorine is 0.003% .
