摘要
在GB/T 2912.1—2009《纺织品甲醛的测定第一部分:游离水解的甲醛(水萃取法)》基础上,系统分析了测量过程中各个影响因素,对各不确定度分量进行了分析和评定。其中,萃取液中甲醛浓度导致的不确定度和重复性测试导致的不确定度对甲醛测量结果的不确定度影响较大。
According to GB/T2912. 1--1998 standard, the formaldehyde content in textiles has been determined. The factors affected the uncertainty in determination was analyzed and evaluated in detail. It is concluded that the uncertainty mainly comes from the concentration of sample solution and the repeated test.
