This International Standard specifies a titrimetric method for the determination of the combined water content of iron ores, using Karl Fischer solution.
This method is applicable to a concentration range of 0,05 to 10 % (m/m) of combined water in natural iron ores, and iron ore concentrates and agglomerates including sinter products.
NOTE - The term "combined water" means that part of the water content of an iron ore that can be removed only at temperatures substantially higher than 100 to 110 °C.
