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.
