通过研究食品包装纸按“GB/T455纸和纸板撕裂度的测定法”进行撕裂指数的测定全过程,系统分析了该法测量结果的不确定度来源并对其进行评定,对各不确定度分量进行了量化,提出了该法的扩展不确定度。
Through the study of food wrapping paper according to “GB / T455 method of determination of tear paper and cardboard ” for the determination of the tear index of the whole process of systematic analysis of the method of measurement of the source of uncertainty and its assessment, The components of uncertainty are quantified, and the extended uncertainty of the method is proposed.
