This part of ISO 4689 specifies a combustion/titration method for the determination of the sulfur content of iron ores. This method is applicable to sulfur contents between 0,002 % (mass fraction) and 0,25 % (mass fraction) in natural iron ores, iron ore concentrates and agglomerates, including sinter products. The results are not affected by the presence of fluoride.
