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).
Klebstoffe - Kurzzeit-Verfahren zum Messen der Emissionseigenschaften von lösemittelarmen oder lösemittelfreien Klebstoffen nach der Applikation - Teil 3: Bestimmung flüchtiger Aldehyde
Diese Europäische Norm legt ein Verfahren zur Bestimmung flüchtiger Aldehyde (hauptsächlich Formaldehyd und Acetaldehyd) und anderer Carbonyl¬verbindungen in der Abluft einer Emissionsprüfkammer nach der Applikation eines lösemittelarmen oder lösemittelfreien Klebstoffes fest, wie in EN 923 beschrieben.
Das Verfahren beruht auf der Chemisorption von flüchtigen Aldehyden durch mit 2,4 Dinitrophenylhydrazin (im Folgenden: DNPH) imprägniertem Silikagel gefüllte Röhrchen oder Patronen mit anschließender Desorption durch Lösemittel, Reinigung und flüssigkeits¬chromato¬graphischer Analyse. Das Verfahren erlaubt die Messung verschiedener Aldehyde, einschließlich Formaldehyd, Acetaldehyd, Propionaldehyd, Butyral¬dehyd, Valeraldehyd, Isovaleraldehyd, Hexanal, Benzaldehyd, 2,5 Dimethylbenzaldehyd, o Tolualdehyd, m Tolualdehyd, p Tolualdehyd, Crotonaldehyd in einem Konzentrationsbereich von etwa 10 ?g/m3 bis 1 mg/m3 (siehe ISO 16000 3).
Adhésifs - Méthodes de mesurage rapide des caractéristiques émissives des adhésifs a teneur faible ou nulle en solvants apres application - Partie 3: Dosage des aldéhydes volatiles
La présente Norme européenne spécifie un mode opératoire permettant de déterminer la présence d’aldéhydes volatils (en particulier les formaldéhydes et acétaldéhydes) et autres composés carbonylés dans l’air d’évacuation d’une chambre d’essai d’émission apres application d’un adhésif a faible teneur en solvants ou a teneur nulle en solvants tel que défini dans l’EN 923.
La méthode repose sur la chimisorption des composés carbonylés volatils sur des tubes de silice ou des cartouches imprégnés de 2,4-dinitrophénylhydrazine (DNPH) avec désorption, nettoyage et analyse chromatographique liquide ultérieures. Elle permet d'identifier plusieurs aldéhydes, notamment les formaldéhydes, acétaldéhydes, propionaldéhydes, butyraldéhydes, valeraldéhydes, isovaléraldéhydes, hexanal, benzaldéhydes, 2,5-dimethylbenzaldéhyde, o-tolualdéhyde, m-tolualdéhyde, p-tolualdéhyde, crotonaldéhyde dans une plage de concentration d’environ 10 ?g/m3 a 1 mg/m3 (voir l’ISO 16000-3).

SAFETY STATEMENT Persons using this European Standard should be familiar with the normal laboratory practice, if applicable. This European Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with any regulatory conditions. 1 Scope 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). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1232, Workplace atmospheres — Pumps for personal sampling of chemical agents — Requirements and test methods EN 13999-1, Adhesives — Short term method for measuring the emission properties of low-solvent or solvent-free adhesives after application — Part 1: General procedure EN ISO 16000-9, Indoor air — Part 9: Determination of the emission of volatile organic compounds from building products and furnishing — Emission test chamber method (ISO 16000-9:2006) ISO 16000-3, Indoor air — Part 3: Determination of formaldehyde and other carbonyl compounds — Active sampling method 3 Principle A sufficient volume of test chamber air is drawn with an appropriate flow through silicagel tubes or cartridges impregnated with 2,4-dinitrophenylhydrazine (DNPH) reagent. Any organic aldehydes and other carbonyl compounds present will react to form non-volatile dinitrophenylhydrazones. Desorption is done with acetonitrile. The resultant solution is concentrated and analysed by high performance liquid chromatography (HPLC) with ultraviolet (UV) detection. Dinitrophenylhydrazone peaks from formaldehyde, acetaldehyde and other aldehydes are identified on the basis of both their respective retention times and their UV responses at more than one wavelength and/or by diode array detection (DAD) and comparison with a derivative product (where available) or standard. Quantification is done by comparison with a relevant aldehyde or a dinitrophenylhydrazone standard.
