Applicable to sulphur contents in the range 0.01 to 1.0% (m/m) in natural iron ores, and iron ore concentrates and agglomerates including sinter products.

This International Standard specifies a barium sulfate gravimetric method for the determination of the sulfur content of iron ores.

This method is applicable to a concentration range of 0,01 to 1,0 % (m/m) of sulfur in natural iron ores, and iron ore concentrates and agglomerates including sinter products.
