Aluminium oxide primarily used for the production of aluminium — Determination of loss of mass at 1 000 degrees C and 1 200 degrees C

Oxyde d'aluminium principalement utilisé pour la production de l'aluminium — Détermination de la perte de masse à 1 000 degrés C et à 1 200 degrés C

This edition has been replaced by ISO 806:2004.

Abstract / scope

The temperatures are arbitrarily selected and specified because there is no specific calcination temperature. There is no criterion for the state of calcination. Therefore, ignition of two test portions taken from the same sample and previously dried in a muffle furnace for 2 h. Calculation by difference in mass. Replaces ISO Recommendation R 806/1968.
