GBW(E)130573门尼粘度标准物质不确定度的评定

摘要

GBW(E)130573 Mooney viscosity certified reference material was developed. The sources of uncertainty of GBW(E)130573 Mooney viscosity certified reference material were analyzed according to JJF 1059.1-2012. The results show that main influencing factors include the dispersity of measurement results of all laboratories, homogeneity and stability of samples, experimental temperature, experimental time, rotating speed of apparatus;The uncertainty of GBW(E)130573 Mooney viscosity certified reference material is 0.9.%研制GBW(E)130573门尼粘度标准物质,该标准物质的不确定度按照JJF 1059.1-2012规定分析不确定度各分量并进行评定.不确定度的来源主要为各定值实验室检测的分散性、样品的均匀性与稳定性、试验温度、试验时间、设备转速.经评定GBW(E)130573门尼粘度标准物质的不确定度为0.9.
