    Abstract - (Show below) - (Hide below)

    Describes a titrimetric method for the determination of the mass fraction of metallic iron in reduced iron ores (direct reduced iron: DRI).

    Scope - (Show below) - (Hide below)

    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.
