ISO 15379-1:2004 provides a method for the determination of the linear expansion of cathode-block materials used in the production of aluminium under external pressure due to sodium penetration.
The linear expansion of the blocks depends on the ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
