中文摘要:
      目的 以卷烟条包装盒为研究对象,依据YC/T 330测定卷烟条包装盒的纵、横向压痕挺度,分析由折痕挺度仪、试样裁切尺寸偏差及测量重复性所引入的测量不确定度值,从而得到卷烟条包装盒压痕挺度的测量不确定度。方法 通过对压痕挺度进行10次独立重复性试验,由计算标准偏差得出标准不确定度值,也称A类不确定度;然后再按B类不确定度评价方法对测量仪器及取样尺寸偏差带来的不确定度进行计算,得出B类不确定度;计算合成不确定度;最后计算扩展不确定度。结果 依据YC/T 330测定卷烟条包装盒A的扩展不确定度U纵=(83.1±6.22)g,k=2;U横=(59.7±4.20)g,k=2。结论 通过评定结果可知,对不确定度影响分量由大到小依次为试样裁切尺寸偏差、测量重复性、折痕挺度仪校准参数。
英文摘要:
      The work aims to take the cigarette packet as the research object to determine its longitudinal and lateral indentation stiffness according to YC/T 330, and analyze the measurement uncertainty value introduced by the crease straightener, size deviation of specimen cutting and measurement repeatability, so as to obtain the measurement uncertainty of the indentation stiffness of cigarette packet. The standard uncertainty value, also known as class A uncertainty, was obtained after the standard deviation was calculated by 10 independent repeatability tests on indentation stiffness. Then, the uncertainty caused by measurement instrument and sampling size deviation was calculated according to the evaluation method of class B uncertainty, and the uncertainty of class B was obtained. The synthetic uncertainty was calculated. Finally, the expansion uncertainty was calculated. According to YC/T 330, the expansion uncertainty of cigarette packet A was Ulongitudinal=(83.1±6.22)g, k=2; Ulateral=(59.7±4.20)g, k=2. According to the evaluation results, the influence components on the uncertainty range from large to small are: size deviation of specimen cutting, measurement repeatability and calibration parameters of crease straightener.
