浸液法测定硅砖真密度的不确定度评定
Uncertainty Evaluation on True Density of Silica Refractory Bricks Tested by Immersion Method
-
摘要: 根据GB/T 5071-1997规定的浸液法对一批硅砖进行真密度测试, 对真密度测试的不确定度分量进行分析、评定、合成, 并给出了不确定度报告。结果表明: 该测试的不确定度主要来自重复性试验。Abstract: According to the immersion method of GB/T 5071-1997, the true density of silica refractory bricks were tested.The uncertainty component which influenced the true density was analyzed and evaluated.The results showed that the important influencing factors of uncertainty were mainly from the repeatability test.
