摘　　要：依据QB/T 2710-2005标准测试皮革断裂伸长率,对测量过程的不确定度来源进行了分析,找出了影响断裂伸长率测量结果的主要因素,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扩展不确定度。The percentage extension after fracture of leather is determined according to QB/T 2710-2005.The source of uncertainty in the whole process of measurement is analysed, and the main factors that affectthe results was found out. The single factor of uncertainty is estimated and combined. The combineduncertainty and expanded uncertainty are presented.
