依据GBT1910-2006《新闻纸》、GB12914-2008《纸和纸板抗张强度的测定》和JJF1059-1999《测量不确定度评定与表示》,分析抗张指数测量不确定度主要来源及评定中的主要影响量,对45.0g/m2新闻纸抗张指数进行不确定度的评定,为其它纸的抗张指数及纸与纸板的抗张强度、裂断长等不确定度评定提供参考。 According to GBT1910-2006 “Newsprint”, GB12914-2008 “Determination of Tensile Strength of Paper and Cardboard” and JJF1059-1999 “Evaluation and Expression of Measurement Uncertainty”, the main sources of uncertainty in measurement of tensile index and the main Impact on the amount of 45.0g / m2 newsprint tensile index uncertainty assessment for other paper tensile index and paper and cardboard tensile strength, fracture length uncertainty assessment provide a reference.
