BS EN 13920-9:2003 – Aluminium and aluminium alloys — Scrap — Part 9: Scrap from aluminium separation processes of non-ferrous shredded materials
1 Scope
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 specified in EN 13920-8.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in prEN 12258-3:2000 and EN 13920-1:2003 apply.
4 Ordering information
The ordering information shall include:
the number of this European Standard (EN 13920-9);
the scrap category (scrap from aluminium separation processes of non-ferrous shredded materials);
the gross mass of the consignment;
the definition of the beginning and end of the period during which the scrap shall be delivered;
any characteristics deviating from those specified under 5.1, for example size of pieces, presence of foreign material.
The ordering information should include:
information about the origin of the scrap;
any information about size and surface condition of the pieces, whenever meaningful.
5 Requirements
5.1 General
In addition to the requirements specified in EN 13920-1, the requirements given in 5.2, 5.3 and 5.4 shall be met.
If the scrap does not meet all these requirements, the supplier shall notify the deviating characteristics to the purchaser and shall obtain his agreement before shipment.
5.2 Characteristics
The scrap shall consist of pieces not smaller than 10 mm and not exceeding 200 mm. The sum of the percentages of oil, grease and other non-metallic materials in the scrap shall not exceed 2 % (mass fraction). The scrap shall be free from metallic foreign materials.
5.3 Chemical composition
If not otherwise agreed, the scrap, after melting, shall have a chemical composition as shown in Table 1.
