Abstract：This article introduced the determination process of manganese in low alloy steel by inductively coupled plasma atomic emission spectrometry (ICP-AES), and established a quantitative mathematical model of the method. Through analyzing the uncertainty of the determination results of manganese in low alloy steel, it is found that the work curve volatility and sample determination repeatability are major factors of the uncertainty in the measurement process and should be given attention, and the rest may be ignored in the process of the actual evaluation. The determination results of manganese content in low alloy steel can be expressed:WMn=0.436%±0.013%, k=2.
