适用范围：This European Standard specifies a procedure for the determination of volatile aldehydes (especiallyformaldehyde and acetaldehyde) and other carbonyl compounds in the exhaust air of an emission testchamber after application of a low-solvent or solvent-free adhesive as defined in EN 923.The method is based on chemosorption of volatile carbonyl compounds with 2,4-dinitrophenylhydrazine (in thefollowing: DNPH) impregnated silica tubes or cartridges with subsequent solvent desorption, clean-up andliquid chromatographic analysis. The method permits measurement of several aldehydes includingformaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, valeraldehyde, isovaleraldehyde, hexanal,benzaldehyde, 2,5-dimethylbenzaldehyde, o-tolualdehyde, m-tolualdehyde, p-tolualdehyde, crotonaldehyde inthe concentration range of approximately 10 μg/m3 to 1 mg/m3 (see ISO 16000-3).
