Carbonaceous materials for the production of aluminium. Baked anodes. Determination of the air permeability Ingestion-build-58320 — the composition1 Scope This International Standard describes a method for the measurement of the air permeability of baked anodes, by determining the resistance to airflow of a specimen of specified volume at room temperature, within the range of air permeability between 0,01 nPm (nanoperms) and 10 nPm. Green anodes are considered to be impermeable to gas. Therefore, this test is most applicable to baked carbon material. NOTE This method can also be used for
