摘　　要：依据DIN53316德国标准测定皮革中禁用偶氮染料,以联苯胺为例,对整个测量过程中不确定度的来源进行了分析,并对不确定度各个分量进行了评定、合成,最后给出了合成不确定度和有效自由度。Banned azo dyes in leather were determined according to German Standard DIN53316. Taking benzdine as an example, the source of uncertainty in the whole process of measurement was analyzed. Each component of uncertainty is estimated and composed. The compositive uncertainty and effective degrees of freedom were given.
