根据JJF 1059. 1—2012《测量不确定度评定与表示》,分析了纸箱边压强度不确定度的主要来源并对其量化,同时对纸箱边压强度不确定度进行了评定。结果表明,影响不确定度的主要因素是重复性测量、仪器的示值误差、数值修约。这批瓦楞纸箱测量结果及不确定度U =(8. 94±0. 23)×103 N/ m,k =2。

The main factors influencing uncertainty of edgewise-crushed resistance of corrugated box were analyzed and measured according to JJF 1059. 1—2012 Evaluation and Expression of Uncertainty in Measurement. The results showed that the source of uncertainty mainly comes from repeated test, accuracy of equipment, and rounding off of value; the uncertainty of edgewise-crushed resistance of the corrugated boxes is U =(8. 94±0. 23)×103 N/ m, k =2.
