Aluminium oxide used for the production of primary aluminium. Particle size analysis for the range 45 um to 150 um. Method using electroformed sieves1 Scope This International Standard 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. This method 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

allowing for identification and prioritisation of countermeasures

It gives guidance for compatibility with gases other than oxygen and it gives detailed requirements for oxygen and oxygen enriched atmosphere compatibility and defines the testing methods for establishing oxygen compatibility of materials (metallic and non-metallic) to be used for cryogenic vessels and associated equipment

It also defines criteria for static strength failure modes
