BS 4993 discusses methods of testing for aluminium fluoride for industrial use. BS 4993-2 is the second part of the BS 4993 multi-series and discusses the determination of iron content of aluminium fluoride for industrial use.
BS 4993-2 is applicable to the determination of iron contents, expressed as Fe2O3, greater than 0.020%.
BS 4993-2 on the determination of iron contents of aluminium fluoride for industrial use is useful for:
A test portion is dissolved by either alkaline or acid fusion, and preliminary reduction of iron (III) is carried out by means of hydroxylammonium chloride. BS 4993-2 provides you with a photometric method for the determination of iron contents of aluminium fluoride for industrial use.
BS 4993-2 provides you with reagents and apparatus required for the procedure of determination of iron. BS 4993-2 guides you on the procedure and calculation. BS 4993-2 helps you with the
determination of iron content of aluminium fluoride.
