ISO 11257:2015 specifies a method to provide a relative measure for evaluating the degree of size degradation and degree of metallization of iron ores, when reduced under conditions resembling those prevailing in shaft direct-reduction processes.
ISO 11257:2015 is applicable to lump ores and hot-bonded pellets.
