摘　　要：为验证综合测试台测量卷烟物理指标的准确性,依据《GB/T 19610-2004卷烟通风的测定定义和测量原理》和《GB/T 22838.5-2009卷烟和滤棒物理性能的测定第5部分:卷烟吸阻和滤棒压降》对卷烟的重量、标准吸阻和总通风度进行检测,依据JJF 1059.1-2012《测量不确定度评定与表示》的方法建立数学公式,分析综合测试台测定卷烟重量、标准吸阻和总通风度的相对标准不确定度。结果表明:A类和B类不确定度中,测试大气温湿度引入的不确定度最大;当卷烟样品重量平均值为642 mg·支^(-1)时,其相对扩展不确定度U_(re)=4.4%(p=95%,k=2);当卷烟样品标准吸阻平均值为1285 Pa时,其相对扩展不确定度U_(re)=4.6%(p=95%,k=2);当卷烟样品总通风度平均值为22.4%时,其相对扩展不确定度U_(re)=5.0%(p=95%,k=2)。In order to verify the accuracy of the comprehensive testing platform in measuring the physical parameters of cigarettes,the weight,standard pressure drop,and total ventilation of cigarettes were tested based on the“GB/T 19610-2004 Definition and Measurement Principles of Cigarette Ventilation”and“GB/T 22838.5-2009 Determination of Physical Properties of Cigarettes and Filter Rods-Part 5:Cigarette Pressure Drop and Filter Rod Pressure Drop”.JJF 1059.1-2012“Evaluation and Expression of Measurement Uncertainty”was used to analyze the relative standard uncertainty of cigarette weight,standard pressure drop,and total ventilation.The results indicated that:Effects of repeatability,reproducibility,airflow rate,testing atmosphere,and standard rods on measurement uncertainty in Class A and Class B uncertainties were investigated,among which the uncertainty introduced by testing temperature and humidity is the greatest;When the average weight of each cigarette sample is 642 mg,its relative expanded uncertainty U_(re)=4.4%(p=95%,k=2);When the average standard pressure drop of the cigarette sample is 1285 Pa,its relative expanded uncertainty U_(re)=4.6%(p=95%,k=2);When the average total ventilation of the cigarette sample is 22.4%,its relative expanded uncertainty U_(re)=5.0%(p=95%,k=2).
