BS ISO 12315:2010

This standard BS ISO 12315:2010 Aluminium oxide primarily used for production of aluminium. Method for calculating the Al₂O₃ content of smelter-grade alumina is classified in these ICS categories:

• 71.100.10 Materials for aluminium production

This International Standard describes methods for calculating and reporting the Al₂O₃ content of smelter-grade alumina, on either a dry or ignited basis, from the results of the determinations in accordance with ISO 806 and AS 2879.7.

NOTE Typical values of a smelter-grade alumina, if reported on a dry basis, would be in the range of 98,5 % to 98,9 % and, if reported on an ignited basis, would be in the range of 99,4 % to 99,7 % mass fraction.
