Zink und Zinklegierungen - Chemische Analyse - Teil 6: Bestimmung von Aluminium und Eisen - FAAS-Verfahren
Diese Europäische Norm legt ein Analyseverfahren zur Bestimmung von Aluminium und Eisen in Zink und Zinklegierungen mittels Atomabsorptionsspektrometrie fest.Das Verfahren ist auf die prEN 1179, prEN 1774 und prEN ...(0020907) festgelegten Produkte anwendbar. Es ist zur Bestimmung eines Eisengehaltes zwischen 0,001 % und 0,1 % und eines Aluminiumgehaltes zwischen 0,001 % und 0,5 % geeignet. ANMERKUNG: prEN 00209021 legt ein Verfahren zur Bestimmung des Aluminiumgehaltes fest, wenn dieser 0,5 % überschreitet.
Zinc et alliages de zinc - Analyse chimique - Partie 6: Dosage de l'aluminium et du fer-Méthode par spectrométrie d'absorption atomique dans la flamme
La présente Norme européenne spécifie une méthode par spectrométrie d'absorption atomique dans la flamme pour le dosage de l'aluminium et du fer dans le zinc et les alliages de zinc. Elle s'applique aux produits spécifiés dans l'EN 988, l'EN 1179, l'EN 1774, l'EN 12844 et l'EN 13283.
Cette méthode convient pour la détermination des teneurs (fractions massiques) du fer comprises entre 0,001 % et 0,5 % et des teneurs (fractions massiques) de l'aluminium comprises entre 0,000 5 % et 0,5 %.
NOTE L'EN 12441-1 spécifie une méthode de dosage de l'aluminium a des teneurs (fractions massiques) comprises entre 3 % et 30 %.
