摘　　要：根据GB 18582-2008标准,用分光光度法测定内墙涂料中甲醛含量,并详细分析和评定了测定影响结果的各个分量,认为在本次测定中,不确定度主要来源于标准曲线的拟合、标准物质及重复测试。This paper described the measurement of the concentration of formaldehyde（CH2O） in the inner coating materials with a spectrometer according to the standard of GB 18582-008.It also analyzes and defines the integrants which can generate noise making up uncertainty of this measurement,and it comes to a conclusion that uncertainty mainly arose from the simulation to standard curve,normal integrants and the repeatability of measurement.
