    Applicable to sulphur contents in the range 0.002 to 0.25% (m/m) in natural iron ores, and iron ore concentrates and agglomerates including sinter products.

    Scope - (Show below) - (Hide below)

    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.
