This International Standard specifies a method to provide a relative measure for evaluating the resistance of iron ores to size degradation by impact and abrasion. It covers the determination of the tumble and abrasion indices.<\/p>\n
This International Standard is applicable to lump ores, sinters, and hot-bonded pellets.<\/p>\n
