摘要
依据JJG 98《非自动天平》与JJF 1059《测量不确定度评定与表示》对电子天平的测量结果的不确定度进行评定。简述电子天平的检定过程,分析了电子天平不确定度的来源及其种类,对不确定度分量及合成不确定度和扩展不确定度进行了评定。
The uncertainty in measurement of electronic balance is evaluated, according to JJG 98 《Non-automatic balance》 and JJF 1059 《Evaluation and expression of uncertainty in measurement》. The verification process of electronic balance is described. The sources and forms of uncertainty are analyzed. And the uncertainty components, combined uncertainty, and expanded uncertainty are evaluated.
