Methods for Determination of Thermal Degradation Index (TDI) and Reduction Degradation Index (RDI) of Iron Oxides: Lump Ores, Sinter and Pellets ( Second Revision )

This standard provides a method for determining the thermal degradation index (TDI) and the reduction degradation index (RDI) of iron oxides. It is applicable to lump ore, sintered ore, and pelletized ore. The procedures outlined in this standard are designed to assess the stability and reactivity of these materials under specific thermal and reduction conditions. The test methods described are intended to ensure consistency and reliability in the evaluation of degradation behavior. The standard includes detailed instructions for sample preparation, testing conditions, and calculation of indices. It serves as a reference for laboratories and industry professionals involved in the analysis of iron ores.
