The International Union of Pure and Applied Chemistry (IUPAC) adopted aluminium as the standard international name for the element in 1990. In 1993, they recognized aluminum as an acceptable variant; the same is true for the most recent 2005 edition of the IUPAC nomenclature of inorganic chemistry. IUPAC official publications use the -ium spelling as primary but list both where appropriate. English Wikipedia follows this standard by adopting the "aluminium" spelling as the sole spelling in chemistry-related articles.
