摘要
依据GB/T 14272-2011《羽绒服装》对羽绒蓬松度的测量不确定度进行了分析和评定,并量化不确定度分量,得出合成不确定度和扩展不确定度。结果表明,羽绒蓬松度测定的不确定度主要来源于测量的随机效应和蓬松度仪的精准性引入的不确定度。
According to the standard of GB/T 14272-2011, all uncertainty components caused in the testing process of down filling power were analyzed and evaluated. The combined uncertainty and expanded uncertainty were calculated. The results show that the main uncertainty components in measurement of down filling power are the random effect and the accuracy of the filling power testing instruments.
