Chemical analysis of ferrous materials - Determination of oxygen content in steel and iron - Part 2: Infrared method after fusion under inert gas

This European Standard specifies an infrared method after fusion under inert gas for the determination of oxygen in steel and iron.
The method is applicable to oxygen contents between 0,0005 % (m/m) and 0,01 % (m/m).

Chemische Analyse von Eisenwerkstoffen - Bestimmung des Sauerstoffgehalts von Stahl und Eisen - Teil 2: Messung der Infrarotabsorption nach Aufschmelzen unter Inertgas

Diese Europäische Norm legt ein Verfahren zur Messung der Infrarotabsorption nach Aufschmelzen unter Inertgas zur Bestimmung des Sauerstoffgehaltes von Eisenwerkstoffen fest.
Das Verfahren ist bei Sauerstoffanteilen zwischen 0,000 5 % (m/m) und 0,01 % (m/m) anwendbar.

Analyse chimique des matériaux ferreux - Détermination de la teneur en oxygène de l'acier et de la fonte - Partie 2: Méthode par absorption dans l'infrarouge après fusion sous gaz inerte

La présente Norme européenne spécifie une méthode de détermination de la teneur en oxygène de l'acier et de la fonte, par absorption dans l'infrarouge après fusion sous gaz inerte.
La méthode est applicable à des teneurs en oxygène comprises entre 0,0005 % (m/m) et 0,01 % (m/m).
