Adhesives - Short term method for measuring the emission properties of low-solvent or solvent-free adhesives after application - Part 3: Determination of volatile aldehydes; German version EN 13999-3:2007
This European standard specifies a proceduce for the determination of value 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 10μm/mto 1mg/m(see ISO 16000-3).
