聚乙烯树脂中灼烧残渣测量不确定度的评定

Evaluation of Uncertainty in Measurement of Ignition Residue in Polyethylene Resin

按照2017年3月1日新实施的GB 31604.6-2016《食品安全国家标准食品接触材料及制品树脂中灼烧残渣的测定》的分析方法处理分析样品,在此基础上建立灼烧残渣不确定度的数学模型。通过分析测定过程不确定度的各种来源,计算各不确定度分量。

Analyze the sample according to the new GB 31604.6-2016 in March 1, 2017, ＂The national standard for food safety, the analysis method for the determination of the ignition residue in the resin of the food contact materials and products＂. On this basis, the mathematical model of uncertainty of ignition residue is established. By analyzing the various sources of uncertainty, the uncertainty components were calculated.
