This International Standard specifies two flame atomic absorption spectrometric methods for the determination of the vanadium content of iron ores.
Method 1 is applicable to vanadium contents between 0,005 % (m/m) and 0,05 % (m/m), and Method 2 to vanadium contents between 0,05 % (m/m) and 0,5 % (m/m) in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
