The article evaluated the uncertainty of the content of banned aromatic amines in textile products in terms of GB/T17592. 1 - 1998 Textiles-test Method of Banned Azo Colourants-gas Chromatography/Mass Spectrometric Method, analyzed and quantified the uncertainty components which affected the measurement results.Through calculation, the uncertainty of the sample mainly came from C0 standard uncertainty, weighing, uncertainty of volume, effect on the recovery rate of sample during the course of extraction and purification and ucertainty from the random effect during the course of measurement. It was obtained that the expanded uncertainties of the content of 2 -naphthylamine, benzidine and 2, 4 - diaminotoluene with higher frequency in 24 kinds of forbidden aromatic amines were respectively 2.128, 2.302 and 4.778 mg/kg.
