Applicable to fluorine contents in the range 0.005 to 1% (m/m) in natural iron ores, and iron ore concentrates and agglomerates including sinter products.

This International Standard specifies an ion-selective electrode method for the determination of the fluorine content of iron ores.

This method is applicable to a concentration range of 0,005 to 1 % (m/m) ¹⁾ of fluorine in natural iron ores, and iron ore concentrates and agglomerates including sinter products.
