摘　　要：为了减小毛纺织品中二氯甲烷可溶性物质检验工作的误差,文章研究了取样质量、水浴温度、二氯甲烷用量、对照实验和索氏萃取器密封状况等因素对毛纺织品二氯甲烷可溶性物质测试结果的影响,结果表明:取样质量、二氯甲烷用量、水浴温度、对照实验和索氏萃取器密封状况等5个因素对测试结果的准确性和可靠性均有影响;相对差异缺乏定义,容易引起歧义;相对差异大于20%要求过于宽松,导致平行试样测试误差对判等结果产生很大影响,建议FZ/T 20018—2010《毛纺织品中二氯甲烷可溶性物质的测定》在修订时予以考虑。In order to reduce testing deviation for determination of dichloromethane-soluble matter in wool textiles, we discussed the effeeting factors of sampling amount, volume of dichloromethane, water bath temperature, contrast test and sealing condition of soxhlet extractor on the determination of dichloromethane-soluble matter in wool textiles. The results showed that such five factors all affect the accuracy and reliability of the result of the test. The relative difference was lack of definition in FZ/T 20018--2010, it was easy to cause confusion, greater than 20% of relative difference was required too loose, it was made great confused on decision levels in wool textiles. It is suggested that FZ/T 20018-- 2010 should consider all the factors above when revised.
