非连续累计自动衡器(料斗秤)测量结果的不确定度评定

The uncertainty measurement of discontinuous accumulating automatic weighing instrument(hopper scale) measurement results

本文主要介绍了在非连续累计自动衡器(料斗秤)试验过程中不确定度来源,并以物料试验为例重点介绍了计算各分量的标准不确定度、合成标准不确定度以及扩展不确定度的方法。

This article mainly introduces the uncertainty source in the discontinuous accumulating automatic weighing instrument （hopper scale） test process, and mainly introduces the calculating each component of the standard uncertainty, synthetic standard uncertainty and expanded uncertainty method to test materials for example.
