ISO 2926:2005

ISO 2926:2005 specifies a dry sieve method using electroformed sieves for determining the mass distribution of the particle sizes in aluminium oxide used for the production of primary aluminium.
ISO 2926:2005 is applicable to calcined aluminium oxide containing a maximum of 20 % mass fraction of particles having a mean diameter exceeding 150 m, and containing a maximum of 15 % mass fraction of particles having a mean diameter less than 45 m.
ISO 2926:2005 is not applicable to the use of wire woven sieves.
