This International Standard specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of tin in iron ores.
This method is applicable to mass fractions of tin between 0,001%and 0,015%in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
