This International Standard specifies a curcumin spectrophotometric method for the determination of the boron content of aluminium oxide primarily used for the production of aluminium. The method is applicable to boron contents, expressed as boron oxide (B2O3), greater than 0,000 6 % (i.e. 0,000 2 % expressed as boron (B)). NOTE —The sensitivity of the method, as may be gathered from the calibration curve, is in fact higher. In the case of a very low blank reading, and with sufficiently sensitive apparatus, the lower limit of application of the method may be extended to 0,000 08 % of boron oxide (B2O3), corresponding to 0,000 025 % of boron (B).

This International Standard specifies an N-benzoyl-N-phenyl-hydroxylamine photometric method for the determination of the vanadium content of aluminium oxide primarily used for the production of aluminium. The method is applicable to products having a vanadium content, expressed as V2O5, between 0,000 3 and 0,016% (mlm), provided that the Cr2O3 and the TiO2 contents do not exceed 0,002 and 0,006 % (m/m) respectively. 1 Special cases (under study) Cr2O3 contents greater than 0,002 % (m/m) and TiO2 contents greater than 0,006 % (m/m).
