Iron ores for blast furnace feedstocks — Determination of the reducibility by the final degree of reduction index

ISO 7215:2007 specifies a method to provide a relative measure for evaluating the extent to which oxygen can be removed from iron ores when reduced under conditions resembling those prevailing in the reduction zone of a blast furnace.

ISO 7215:2007 is applicable to lump ores, sinters and hot-bonded pellets.
