电子天平示值误差测量结果的不确定度评定

Uncertainty Evaluation of the Measurement of Electronic Balance Indication Error

依据JJG 1036–2008《电子天平检定规程》,分析了电子天平示值误差测量结果不确定度的来源,以最大称量点200 g为例,对不确定度分量进行了评定与计算。当最大称量为200 g时,扩展不确定度为0.18 mg(k=2)。

The sources of measurement uncertainty of electronic balance indication error were analysed according to JJG 1036-2008 Electronic Balance Verification Regulation. The largest weighing 200 g was taken for example, uncertainty components were calculated. The expanded uncertainty was 0.18 mg（k=2.01） as the largest weighing was 200 g.
