Specifies a spectrophotometric method using N-benzoyl-phenylhydroxylamine (BPHA) for the determination of the mass fraction of vanadium in iron ores.

This part of ISO9683 specifies a spectrophotometric method using N-benzoyl-phenylhydroxylamine (BPHA) for the determination of the mass fraction of vanadium in iron ores.

This method is applicable to mass fractions of vanadium between 0,005 and 0,5%in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
