Based on China Nation Standard (CNS) GB/T 10345-2007 “The analysis method of China spirits”, The content of ethyl acetate in Mild aromatic Chinese spirits have been determinated using gas chromatography. Accord-ing to JJF 1059.1-2012, the source of uncertainty in the whole measurement process has been analyzed, the mathematical model of uncertainty in the determination has been builded, the influence factors of uncertainty has been found, the uncertainty has been evaluated. It accurately reflects the confidence and authenticity of the deter-mination. The results shows that, the determination of ethyl acetate content in Chinese spirits has a higher accura-cy, it up to the requirements of testing laboratory on ISO/IEC 17025 and meets the China national standards.
