This part of ISO 4696 specifies a method to provide a relative measure for evaluating the degree of size degradation of iron ores when reduced with carbon monoxide, carbon dioxide, hydrogen and nitrogen, under conditions resembling those prevailing in the low-temperature reduction zone of a blast furnace.
This part of ISO 4696 is applicable to lump ores, sinters and hot-bonded pellets.
