依据国家计量技术规范《测量不确定度评定与表示》，对气相色谱一质谱法测定皮革及其制品中的富马酸二甲酯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及扩展不确定度。当富马酸二甲酯测定结果为0.02mg／kg时，扩展不确定度为0．02mg／kg。
依據國傢計量技術規範《測量不確定度評定與錶示》，對氣相色譜一質譜法測定皮革及其製品中的富馬痠二甲酯整箇測量過程中不確定度的來源進行瞭分析，併對不確定度各箇分量進行瞭評定、閤成，最後給齣瞭閤成不確定度及擴展不確定度。噹富馬痠二甲酯測定結果為0.02mg／kg時，擴展不確定度為0．02mg／kg。
의거국가계량기술규범《측량불학정도평정여표시》，대기상색보일질보법측정피혁급기제품중적부마산이갑지정개측량과정중불학정도적래원진행료분석，병대불학정도각개분량진행료평정、합성，최후급출료합성불학정도급확전불학정도。당부마산이갑지측정결과위0.02mg／kg시，확전불학정도위0．02mg／kg。
According to National Measurement Technology Criterion （Evaluation and Expression of Uncer- tainty in Measurement）, Dimethyl fumarate in leather and leather products were determined by ultrasonic extraction and GC-MS, the source of uncertainty in the whole process of measurement was analyzed.Each component of uncertainty is estimated and composed.The composed and expanded uncertainties were given. When the content of dimethyl fumarate was 0.3 mg/kg, the expanded uncertainty was 0.02 mg/kg
