摘　　要：研究了塑料一次性餐饮具高锰酸钾消耗量不确定度的评定,分析了重复性测试、高锰酸钾标准溶液、移取浸泡液体积、测量样品面积、滴定用量等分量对于测量不确定度的影响,对结果的分析表明,重复性测试对于不确定度结果的影响最大。We first analyzed the uncertainty determination of the potassium permanganate consumption of plastic disposable tableware. And we also discussed the influences of repeatability test, potassium permanganate standard solution, volume of immersion solution, measured sample area, titration dosage and other components on measurement uncertainty. In conclusion, the repeatability test has the greatest impact on the uncertainty results.
