Adhesives - Short term method for measuring the emission properties of low-solvent or solvent-free adhesives after application - Part 3: Determination of volatile aldehydes
This European Standard specifies a procedure for the determination of volatile aldehydes (especially
formaldehyde and acetaldehyde) and other carbonyl compounds in the exhaust air of an emission test
chamber 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 the
following: DNPH) impregnated silica tubes or cartridges with subsequent solvent desorption, clean-up and
liquid chromatographic analysis. The method permits measurement of several aldehydes including
formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, valeraldehyde, isovaleraldehyde, hexanal,
benzaldehyde, 2,5-dimethylbenzaldehyde, o-tolualdehyde, m-tolualdehyde, p-tolualdehyde, crotonaldehyde in
the concentration range of approximately 10 μg/m³ to 1 mg/m³ (see ISO 16000-3).
Diese Europäische Änderung A1:2008-10 enthält Änderungen zu den Unterabschnitt 6.1.
