Direct reduced iron. Determination of metallic iron. Bromine-methanol titrimetric method Ingestion-build-103253 governmental and social enterprises1 Scope This International Standard specifies a titrimetric method for the determination of the mass fraction of metallic iron in reduced iron ores (direct reduced iron: DRI). This method is applicable to mass fractions of metallic iron between 15 % and 95 % in DRI. NOTE The term metallic iron means those forms of iron not bonded to oxygen or not present as pyrite.
