Iron ores for blast furnace and direct reduction feedstocks — Determination of the tumble and abrasion indices

Minerais de fer pour charges de hauts fourneaux et pour procédés par réduction directe — Détermination des indices de cohésion et d'abrasion

This edition has been replaced by ISO 3271:2015.

Abstract / scope

ISO 3271:2007 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.

ISO 3271:2007 is applicable to lump ores, sinters and hot-bonded pellets.
