CEN/TC 132/WG 20 - Scrap

This European Standard specifies characteristics, chemical composition and metal yield of decoated aluminium scrap obtained by decoating mixed used aluminium packagings through various processes, e.g. pyrolysis, mechanical delamination, chemical delamination or a combination of these. It also applies to aluminium scrap separated from the bottom ashes of incinerators.
EXAMPLE   A mix of used aluminium packaging scrap of different alloys which were decoated to be used for melting or other forms of metal recycling.

This part of this European Standard specifies characteristics, chemical composition and metal yield of aluminium scrap consisting of skimmings, drosses and spills. It also applies to the metallic obtained by dry processing of drosses and skimmings. Full lots of dross fines with particle size smaller than 0,8 mm, or loft of drosses with a metal yield less than 30% are not within the scope of this Standard.

This part of this European Standard specifies the characteristics, chemical composition and metal yield of the aluminium scrap fraction obtained by flotation or other separation processes of non ferrous shredded materials. It applies to scrap consisting mainly of aluminium castings, but also containing aluminium scrap from wrought products. EXAMPLE The aluminium fraction as obtained by flotation of the material described in prEN 132/200-8.

This European Standard specifies characteristics, chemical composition and metal yield of new and old scrap recovered from wire or cable of unalloyed aluminium with a chemical composition not less than 99,5 % aluminium, or of defined aluminium alloys.
Example
New scrap from manufacturing of cables and wires.
Old scrap from used aluminium cables obtained from dismantling of electrical lines.

This part of this European Standard specifies characteristics, chemical composition and metal yield of scrap which consists of aluminium turnings of one single wrought or cast specified alloy (e.g. EN 573-3 or EN 1706). EXAMPLE Scalpings, millings, borings from plates, extruded profiles, castings, etc..

This part of this European Standard specifies, characteristics, chemical composition and metal yield of scrap consisting of one single wrought aluminium alloy. It does not apply to turnings which are covered by part 12 of this Standard. EXAMPLE Production scraps of sheet, strip, tubes, extruded or drawn profiles, ends of extrusion ingots etc..

This part of this European Standard specifies characteristics, chemical composition and metal yield of aluminium scrap consisting of aluminium castings in entire or fragmented pieces. EXAMPLES - Production scrap from foundries, e. g. rejected pieces and risings ;
- collected castings of various alloys e.g. from maintenance or dismantling of vehicles, household appliances, industrial machinery etc. ;
- selected whole castings, e. g. pistons, wheels.

This part of this European Standard specifies characteristics, chemical composition and metal yield of aluminium scrap (predominantly old scrap) consisting of two or more wrought aluminium alloys. EXAMPLES - Mix of used pots and pans, TV antennas, road signals, car-plates, window frames and other end-of-life aluminium objects ; - scrap from demolition of buildings.

This part of this European Standard specifies characteristics, form, chemical composition and metal yield of scrap consisting of a mixture of used aluminium packagings. This mixture includes aluminium foil laminated with paper or plastics having a metal yield less than 28%.

This part of this European Standard specifies requirements for aluminium-containing shredded material mixed with other metals and non-metallic components (rubber, plastic, glass etc) produced by shredding end-of-life vehicles, household appliances etc. It is applicable to material intended for further preparation/selection processes by the user to get the aluminium scrap separated from other foreign materials.

This part of this European Standard specifies characteristics, chemical composition and metal yield of aluminium scrap in the form of turnings consisting of two or more alloys. EXAMPLE Scalpings, millings, borings from plates, extruded profiles, castings etc..

This part of this European Standard specifies characteristics and chemical composition of scrap from aluminium/copper radiators with a copper content sufficiently high to allow its use as alloying material in the production of aluminium alloys. EXAMPLE Prepared radiators from vehicles, refrigerators or from industrial equipment.

This part of this European Standard specifies, characteristics, chemical composition and metal yield of new aluminium scrap consisting of a mix of pieces obtained from two or more wrought aluminium alloys of the same series.

This European Standard specifies characteristics, chemical composition and metal yield of unalloyed aluminium scrap with a chemical composition of not less than 99,5 % aluminium.
Example
Production scrap from sheet, strip, tube etc. where unalloyed aluminium is used.
New and old scrap from lithographic sheet.
Old scrap from various products selected to meet the specifications of this standard.

This part of this European Standard specifies characteristics, form, chemical composition and metal yield of scrap consisting of used aluminium beverage cans. NOTE 1 This scrap is commercially known as UBC (Used Beverage Cans) NOTE 2 Complete cans, after removal of the liquid content, even if not obtained from post-consumer collection schemes, are within the scope of this standard and are also regarded as UBC.

This European Standard specifies general requirements and guidelines for the delivery and classification of the different categories of aluminium scrap, including quality requirements, sampling and tests.
NOTE   Special requirements and guidelines for each of the scrap categories are specified in prEN 13920 2 to prEN 13920 16.
