摘　　要：采用电位滴定法和化学分析法测定BDNPF/A酸值,对这2种方法进行了精密度和准确度评价与比较。结果表明,这2种方法均可取得满意结果。对化学分析法的不确定度进行了评定和分析,经验证,滴定试样消耗的标准溶液体积对不确定度的贡献最大。Acid value of BDNPF/A was determined by potentiometric titration method and chemical analysis method. The precision and accuracy of the two methods are evaluated and compared. The results show that the two methods can all obtain satisfied effects. The uncertainty of the chemical analysis method is evaluated and analyzed. It is verified that the contribution of the standard solution volume consumed for titrating sample on uncertainty is the largest.
