| Abstract: | 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% . |
