摘　　要：GB/T 30398-2013《皮革和毛皮化学试验致敏性分散染料的测定》中规定了皮革和毛皮中的致敏性分散染料的测定方法,按照GB/T 30398-2013标准用HPLC法测定皮革中可萃取致敏性分散染料,以分散黄3为例,分析了测试过程中不确定度的来源,对各不确定度分量进行评定及合成,并计算得出合成不确定度和扩展不确定度。结果表明,对本测试方法影响较大的不确定度分量是标准物质配制。在重复测定的条件下,测定结果的不确定度仅与溶液中的致敏性分散染料浓度有关。Leather and Fur-determination of Allergenic Disperse Dyestuffs of GB/T 30398-2013 prescribed the methods for the determination of allergenic disperse dyestuffs in the leather and fur. According to the standard of GB/T 30398-2013, the extractable allergenous disperse dyestuffs in the leather and fur was detected by HPLC. Taking disperse yellow 3 for example, source of uncertainties were analyzed, uncertainty components were evaluated and composed, and the composed and expanded uncertainties were obtained. Results showed that the main factors affecting the determination were preparation of reference materials. Under repeated measurement conditions, uncertainty of determination was only related to the concentration of allergenous disperse dyestuffs.
