BS EN 12258-3:2003 - Aluminium and aluminium alloys — Terms and definitions — Part 3: Scrap

This European Standard contains definitions of termsrelated to scrap of aluminium and aluminium alloyswhich are helpful for the communication within the
aluminium industry and between the industry and theauthorities.
Definitions of general terms which are helpful for thecommunication within the aluminium industry are laiddown in EN 12258-1.
NOTE1ln some terms and definitions “aluminium” isused for “”aluminium and aluminium alloys”.
NOTE2Definitions of other standards or regulationsapplying to a broader field of application which includes the
field of application of this Standard can be more generalthan the definitions of identical terms in this standard; they
can be found in the relevant documents.
NOTE 3The definitions ofterms indicatingdifferenttypes of scrap do not contain requirements,e.g. on metalyield or chemical composition related to the scrap categoryto which this type of scrap belongs.
Aglossary (Clause 10) comprises all terms which aredefined in this Standard and their translations in alphabeticalorder.
2 Nomative references
This European Standard incorporates by dated or undated reference, provisions from other publications.

3 General
3.1 (aluminium) scrap raw material, destined for trade and industry, mainly consisting of aluminium and/or aluminium alloys, resulting from the ollection and/or recovery of metal that arises at various stages of fabrication: products after use. to be used for the production of wrought and cast alloys and for other production processes
3.2 new scrap scrap arising from the production and fabrication of aluminium products
3.3 old scrap scrap arising from products after use
4 Types of scrap
4.1 skdmmings material composed of intimately mixed aluminium and aluminium oxides, which have been removed from the surface of the molten metal or from the bottom and walls of liquid metal containers, e. g. furmaces or transport ladles or transfer channels NOTE The same material with lower metal content is often cal led “dross”.
4.2 metallcas material produced by crushing or grinding of skimmings by means of ball mills, hammer mills, impactors, etc. and the selection of the coarser fraction where most of the metallic aluminium is concentrated, by screening
4.3 spills sorap with high recoverable aluminium content resulting from the solidification of metal which spilled over the rim or penetrated through leakages of liquid metal containers, e. g. furnaces, crucibles, troughs or dies
