摘要
按照GB/T 6890-2012《锌粉》中附录B的规定,用化学滴定法测定锌粉中金属锌含量,通过对影响测量结果的不确定度分量的分析和量化,给出锌含量测量结果不确定度的评估方法。
According to the provisions of the appendix B of GB/T 6890-2012, the metal zinc content in the zinc powder is determined by chemical titration. Through the uncertainty components of affect the measurement result of analysis and quantitative, evaluation of uncertainty on the metal zinc content in the zinc powder was given.
