煤的视相对密度测定结果不确定度评定OA
Evaluation on the uncertainty of experimental results of coal’ apparent relative density
根据GB/T 6949-2010《煤的视相对密度测定方法》[1],按照JJF1059.1-2012[2],对煤的视相对密度测定过程中的不确定度分量进行识别,并分别对各不确定度分量进行计算,得出合成标准不确定度,最终确定扩展不确定度和不确定度报告。
Based on GB/T 6949—2010 “determination of apparent relative density of coal” and the standard JJF1059. 1—2012, the uncertainty components in the determination process of apparent relative density of coal were identified and calculated.Then the combined standard uncertainty is achieved .At last, the expand uncertainty and uncertainty report was determined .
