Applicable to ores containing between 0.01% and 5% (m/m) of diphosphorus pentoxide.

This International Standard specifies a molybdenum blue spectrophotometric method for the determination of phosphorus in aluminium ores and minerals.

The method is applicable to materials having phosphorus contents, expressed as diphosphorus pentoxide between 0,01 and 5 % (m/m).

The arsenic content of the sample does not affect the determination.
