This European Standard defines general terms which are helpful for the communication within the aluminium industry and its customers relating to products of aluminium and aluminium alloys. It includes terms dealing with aluminium products, processing, sampling and testing, product characteristics and different types of visual quality characteristics. It does not include terms dealing with bauxite mining, alumina and anode production and aluminium smelting. This European Standard tries to be as close as possible to terms and definitions as used in other standards or documents. NOTE For materials other than aluminium, different definitions can apply for terms which are defined in this document.
