List of articles that use an English language variant that is not en-US (American English). Can be: |engvar=en-GB, en-OED. Note that formal IUPAC spellings are used everywhere (see Wikipedia:Naming conventions (chemistry)#Element names). So for example, irrespective of the language variant, all articles use "aluminium" not "aluminum". (Except when that spelling is the issue to be described).
