1 Scope This document specifies the requirements for the properties and condition of a specific range of tradeable secondary raw materials with a predominant zinc content. This document defines these materials uniformly at the European level so that they can be traded within the economic cycle as raw materials with product character and their recycling is carried out specific to the material. 2 Normative references The following referenced document is indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12844,
Zinc and zinc alloys — Castings — Specifications.
3 Terms and definitions For the purposes of this document, the following terms and definitions apply: 3.1 groups of secondary raw materials
3.1.1 metallic scrap
3.1.1.1 new zinc and zinc alloy scrap zinc and zinc alloy new or unused such as rejected parts, stampings and/or other by-products from processing 3.1.1.2 old zinc and zinc alloy scrap zinc and zinc alloy-based used or end of life material with or without foreign attachments and/or foreign materials 3.1.2 Drosses and skimmings
3.1.2.1 drosses by-products from melting and/or galvanizing operations consisting of mainly metallic materials predominantly of zinc and iron 3.1.2.2 skimmings by-products from melting and/or galvanizing operations consisting of a mixture of predominantly zinc and zinc ox-ide, untreated or treated 3.2 foreign materials material, other than as specified in this standard, whether metallic or non-metallic including free iron SIST EN 14290:2004

5 3.3 coated, plated or enamelled material material with any kind of coating or plating, independent of the process of coating or plating, e.g. paint, varnish, print, plastics or metals (e.g. aluminium, chromium, nickel, tin) 3.4 free iron ferrous materials (e.g. steels) either magnetic or non-magnetic 3.5 moisture any liquid that adheres to the material
(less than 0,2% for metallic material) when it reaches the point of delivery due to fabrication, usage or pick-up during storage 3.6 inspection lot consignment or a part thereof submitted for inspection by the purchaser 3.7 representative sample sample, fully representing the range of scrap in an inspection lot 3.8 zinc content total elemental zinc content, either in metallic or compound form 3.9 metal yield mass of gained metal after drying and melting with a temperature up to 500 °C, using flux if necessary 3.10 unmeltables fraction of the consignment not molten at a temperature up to 500 °C 4 Designation The product designation provides a standardized pattern of designation from which a rapid and unequivocal description of a product is conveyed in communication. It provides mutual comprehension at the international level with regard to products which meet the requirements of the relevant document. The product designation is no substitute for the full content of the standard. The product designation for products to this standard shall consist of:  denomination (Secondary raw material);  number of this document (EN 14290);  material type (see annexes A and B). SIST EN 14290:2004

The derivation of a product designation is shown in the following example. EXAMPLE Secondary raw material conforming to this standard, material type S-ZnA.1.1, shall be designated as follows: Secondary raw material EN 14290 – S-ZnA.1.1 Denomination
Number of this document Material type 5 Ordering information In order to facilitate the enquiry, order and confirmation of order procedures between the purchaser and the supplier, the purchaser shall state on his enquiry and order the following information: a) quantity of material required (mass); b) denomination (Secondary raw material); c) number of this document (EN 14290); d) material type (see annexes A and B). NOTE It is recommended that the product designation, as described in clause 4, is used for items b) to d). In addition, the purchaser shall also state on the enquiry and order any of the following, if required: e) form of packaging. EXAMPLE Ordering details for 20 t secondary raw material conforming to EN 14290, material type S-ZnA.1.1: 20 t Secondary raw material EN 14290 – S-ZnA.1.1 6 Requirements 6.1 Characteristics, condition, zinc content, moisture The characteristics, condition, zinc content, moisture shall conform to the requirements for the appropriate material given in annexes A and B. 6.2 Composition The compositions given in annexes A and B refer to the analytical results obtained, using appropriate documents or other methods by agreement, from a representative sample taken from an inspection lot. 6.3 Additional requirements If not otherwise specified in annexes A and B, the following applies: The secondary raw material shall not contain:  mica, asbestos, plastic, rubber, paper impregnated with oil, oil, grease;  materials being recognized as substances that deplete the ozone layer of the earth;  explosive materials. No radioactively contaminated secondary raw material or radioactively contaminated substances adhering to the secondary raw material or mixed with the secondary raw material shall be accepted.

7 7 Inspection of incoming material 7.1 General The inspection scheme given in Figure 1 shall be applied. The test procedures shall be carried out on representative samples. For expression of results, the rounding rules given in 7.4 shall be used. In case of dispute with respect to sampling or testing methods or their results, arbitration shall be agreed between the purchaser and the supplier.
9 7.2 Test procedures The test procedures given in Table 1 shall be used as appropriate. Table 1 — Test procedures Characteristic Test procedure Moisture — Estimation — Weighing before and after removal of the moisture
