Ferronickels - Determination of sulfur content - Infrared absorption method after induction furnace combustion (ISO 7526:2020)

This document specifies an infrared absorption method after combustion in an induction furnace for the determination of the sulfur content in ferronickels in the range of 0,002 % to 0,12 %.
The method is applicable to normal production operations. It uses commercially available equipment, which is calibrated using steel and/or ferronickel certified reference materials (CRMs).

Ferronickel - Bestimmung des Schwefelgehalts - Infrarot-Absorptionsverfahren nach Verbrennung im Induktionsofen (ISO 7526:2020)

Dieses Dokument legt ein Infrarot-Absorptionsverfahren nach Verbrennung im Induktionsofen für die Bestimmung des Schwefelgehalts in Ferronickel im Bereich von 0,002 % bis 0,12 % fest.
Das Verfahren ist auf den normalen Produktionsbetrieb anwendbar. Es werden kommerziell verfügbare Geräte verwendet, die mit Hilfe von zertifizierten Stahl- und/oder Ferronickel-Referenzmaterialien (ZRM) (en: certified reference materials, CRMs) kalibriert werden.

Ferronickels - Détermination de la teneur en soufre - Méthode par absorption dans l'infrarouge après combustion dans un four à induction (ISO 7526:2020)

Le présent document spécifie une méthode par absorption dans l'infrarouge après combustion dans un four à induction, pour la détermination du soufre à des teneurs comprises entre 0,002 % et 0,12 % dans les ferronickels.
La méthode est applicable aux opérations de production normales. Elle utilise un appareillage disponible sur le marché, étalonné au moyen de matériaux de référence certifiés (MRC) en acier et/ou ferronickel.
