摘要
按照GB/T 5009.60-2003《食品包装用聚乙烯、聚苯乙烯、聚丙烯成型品卫生标准的分析方法》处理分析样品,探索测定食品包装用聚丙烯成型品蒸发残渣的不确定度评定方式,建立蒸发残渣测量不确定度数学模型。通过分析测定过程中不确定度的来源,计算各个不确定度的分量。该检测方法的不确定度评定结果为:相对标准不确定度为1.289mg/L,扩展不确定度为2.58 mg/L(k=2)。
Sample pretreatment and analysis were performed according to GB/T 5009.60-2003 Hygienic standard of products polyethylene,polystyrene and polypropyrene for Food Packaing to explore the evaluation way of the uncertainty determination of evaporation residue in products of polypropyrene for food packaing,as well as to establish mathematical models to develop uncertainty evaluation for the determination.Each uncertainty component was calculated by analyzing the source of uncertainty generated during the determination steps.and the result of uncertainty was showed that the relative standard uncertainty was 1.289 mg/L,and the expanded uncertainty was 2.58 mg/L（k=2）.
