This International Standard specifies a combustion method for the determination of the sulfur content of iron ores.
This method is applicable to a concentration range of 0,002 to 0,25 % (m/m) of sulfur in natural iron ores, and iron ore concentrates and agglomerates including sinter products. The results are not affected by the presence of fluoride.
