摘要
对用色度计测试瓶级PET切片色值的不确定度进行了评定,结果表明,定期对标准色板进行检定,严格样品测试的操作细节,确保样品颗粒度均匀,可以达到减少不确定度的目的。
The uncertainty of measuring colour value of bottle grade PET chips with colorimeter was evaluated.The results showed that the uncertainty of a measurement for this method can be reduced by calibrating the standard plate periodically and controlling the sample operation details strictly,especially the granularity of sample.
