This standard specifies 24 methods for the determination of prohibited azo dyestuff in furniture products and their materials. The method consists of reducing azo dyestuff in the sample to aromatic amine intermediates with citrate buffer, followed by liquid-liquid extraction using a diatomaceous earth column to extract the aromatic amine into tert-butyl methyl ether. After the extract is condensed, the presence of azo dyestuff is determined by gas chromatograph-mass spectrometry analysis. The standard applies to the testing of furniture and its materials to ensure that they comply with environmental protection and safety regulations.
