Plastics - Polyurethane raw materials - Determination of isocyanate content (ISO 14896:2009)

ISO 14896:2009 specifies two methods for the measurement of the isocyanate content of aromatic isocyanates used as polyurethane raw materials. Method A is primarily applicable to refined toluene diisocyanate (TDI), methylene-bis-(4-phenylisocyanate) (MDI) and their prepolymers. Method B is applicable to refined, crude or modified isocyanates derived from toluene diisocyanate, methylene-bis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate. It can also be used for isomer mixtures of toluene diisocyanate, methylene-bis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate. Other aromatic isocyanates may be analysed by this method if precautions are taken to verify suitability. It is not applicable to blocked isocyanates.

Kunststoffe - Polyurethanrohstoffe - Bestimmung des Isocyanatanteils (ISO 14896:2009)

Diese Internationale Norm legt zwei Verfahren zur Bestimmung des Isocyanatanteils von aromatischen Isocyanaten fest, die als Polyurethanrohstoff verwendet werden. Verfahren A ist in erster Linie auf reines Toluoldiisocyanat (TDI), 4,4´-Methylendi-(phenylisocyanat) (MDI) und deren Vorpolymere anwendbar. Ver-fahren B ist auf reine, rohe oder modifizierte, von Toluoldiisocyanat, 4,4´-Methylendi-(phenylisocyanat) und Polymethylenpolyphenylisocyanat abgeleitete Isocyanate anwendbar. Es kann auch bei Isomergemischen von Toluoldiisocyanat, 4,4´-Methylendi-(phenylisocyanat) und Polymethylenpolyphenylisocyanat Anwendung finden. Wenn die Eignung des Verfahrens vorsorglich nachgewiesen wurde, dürfen auch andere aromatische Isocyanate damit analysiert werden. Das Verfahren ist nicht auf inaktivierte Isocyanate anwendbar.

Plastiques - Matières premières des polyuréthannes - Détermination de la teneur en isocyanate (ISO 14896:2009)

L'ISO 14896:2009 spécifie deux méthodes pour la détermination de la teneur en isocyanate des isocyanates aromatiques utilisés comme matières premières pour polyuréthannes. La méthode A est principalement applicable au toluylène-diisocyanate (TDI), au méthylène-bis-(4-phénylisocyanate) (MDI) purifiés et à leurs prépolymères. La méthode B est applicable aux isocyanates purifiés, bruts ou modifiés dérivés du toluylène-diisocyanate, du méthylène-bis-(4-phénylisocyanate) et du polyméthylène polyphénylisocyanate. Cette méthode peut également être utilisée avec les mélanges d'isomères de toluylène-diisocyanate, de méthylène-bis-(4-phénylisocyanate) et de polyméthylène polyphénylisocyanate. D'autres isocyanates aromatiques peuvent être analysés selon cette méthode si l'on prend soin de vérifier son adéquation. La présente méthode n'est pas applicable aux isocyanates séquencés.
