| 目的 为提高包装用塑料复合膜、袋中溶剂残留的检测水平，建立溶剂残留测定结果的不确定度评定方法模型。方法 以GB/T 10004—2008《包装用塑料复合膜、袋 干法复合、挤出复合》中溶剂残留的检测方法为基础，参考相关标准和文献系统分析该法测量结果的不确定度来源，并对不确定度各个分量进行评估和合成。结果 样品中溶剂残留总量的测定结果可表示为(22.40+1.421) mg/m2，k=2，P=95%。样品中苯系物残留量的测定结果可表示为(1.748+0.090 06)mg/m2，k=2，P=95%。最小二乘法得到的拟合校准工作曲线是溶剂残留结果测量不确定度的主要来源。结论 溶剂残留测量结果的不确定度可作为表征测量结果准确度的指标之一。 |

| The aim of this work was to raise the detection level and study the model of the uncertainty evaluation method of solvent residues in laminated films and pouches. Solvent residues were tested according to the standard GB/T 10004—2008 "Plastic laminated films and pouches for packaging-dry lamination and extrusion lamination", The sources of uncertainty of the test result were evaluated and quantified according to some relevant standard and document. The result of the total solvent residues of sample in laminated films and pouches was expressed as: (22.40+1.421)mg/m2, k=2, P=95%.The result of the benzene series solvent residues of sample in laminated films and pouches was expressed as: (1.748+0.090 06)mg/m2, k=2, P=95%. The result showed that the uncertainty by fitting regression calibration line had the largest affect to the determination result. The uncertainty evaluation results can be used as one of the accuracy index of the test result. |
