See introduction 3.7 structure load-bearing element construction, i.e. organized assembly of connected parts designed to provide mechanical resistance and stability to the works [Commission Guidance Paper L concerning the Construction Products Directive 89/106/EEC] 3.8 structural relating to a structure [Commission Guidance Paper L concerning the Construction Products Directive 89/106/EEC] 3.9 structural material/constituent material material or constituent product with properties which enter into structural calculations or otherwise relate to the mechanical resistance and stability of works and part thereof, and/or their fire resistance, including aspects of durability and serviceability, such as castings or semi-finished wrought products made of aluminium and aluminium alloys [Commission Guidance Paper L concerning the Construction Products Directive 89/106/EEC] 3.10 structural component components to be used as load-bearing part of works designed to provide mechanical resistance and stability to the works and/or fire resistance, including aspects of durability and serviceability; it can be used directly as delivered or for inclusion in a construction work [Commission Guidance Paper L concerning the Construction Products Directive 89/106/EEC] 3.11 structural kit kit consisting of structural components to be assembled and installed on site; the assembled system made from the structural kit is a “structure” [Commission Guidance Paper L concerning the Construction Products Directive 89/106/EEC] 3.12 technical specifications harmonized European Standard (hEN) and European Technical Approval (ETA) for construction products [Commission Guidance Paper L concerning the Construction Products Directive 89/106/EEC] 3.13 wrought product product obtained by hot and/ or cold working processes such as extruding, forging, hot rolling, cold rolling or drawing, either exclusively or in combination; examples for wrought products are rod/ bar, wire, tube, profile, sheet, strip and forging [EN 12258-1:1998]

4.3.2.1 General The requirements and test methods on structural material for construction works shall be as specified in the standards given in Table 1.

4.3.2.2 Mechanical properties 4.3.2.2.1 General The mechanical properties shall conform to those specified in the European Standards given in Table 1 and achieve the minimum values for:  elongation;  tensile strength;  yield strength;  fatigue strength (where required);  bendability (where required). 4.3.2.2.2 Mechanical properties of products under cyclic loading/fatigue strength The material shall be classified on a case-by-case base in accordance with the intended use as follows:  Class I The product is not subject to fatigue.  Class II The product is subject to fatigue and fatigue properties are specified in prEN 1999-1-3.  Class III The product is subject to fatigue, but fatigue properties are not specified in prEN 1999-1-3. For Class III, the fatigue testing shall be carried out according to:  requirements on fatigue testing of extruded, rolled or forged products as specified in Annex A. If no Class is specified in the ordering information, the manufacturer shall obtain the requirements in accordance with this European Standard from the purchaser. 4.3.2.2.3 Bendability The structural material shall be classified as specified in Annex B. Bendability of new alloys may be established with the use of application rules or extended application rules developed for the purpose. 4.3.3 Weldability The weldability of aluminium and aluminium alloys shall be declared according to Table C.1 and Table C.2 of Annex C of prEN 1999-1-1. NOTE
A new or modified alloy could demonstrate weldability suitability by assessment leading to European Technical Approval until the Eurocode classification is extended to include the new or modified alloy. 4.3.4 Restrictions to avoid regulated substances The manufacturer shall ensure that there are no emissions of any substances hazardous to health or to the environment in excess of the legally permitted level in the member state of destination. Aluminium scrap shall be as in EN 13920-1.

Aluminium and aluminium alloys as specified in EN 573-3 and EN 1706 are environmentally friendly with reference to the release of cadmium, chromium (VI), mercury and the emission of radioactivity. 4.3.5 Durability Durability for a reasonable economic working lifetime is generally assured by the inherent corrosion resistance of aluminium and its alloys. Under exceptional atmospheric conditions or demanding use, the selection of the material shall take into account all relevant requirements. The durability of aluminium and aluminium alloys shall be declared according to prEN 1999-1-1 Table 3.1 a, Table 3.1 b or prEN 1999-1-4 Table 3.1. The organic coating of coated sheet and strip shall be tested in accordance with EN 1396. The durability of the coated sheet and strip shall not be adversely affected by bending. When the material is subject to bending, the flexibility of the organic coating shall be assessed by subjecting the material to an additional bend test in accordance with EN ISO 1519. The result shall be expressed as measured bend radius "T". NOTE
A new or modified alloy could demonstrate durability suitability by assessment leading to European Technical Approval until the Eurocode classification is extended to include the new or modified alloy. 5 Evaluation of conformity 5.1 General The conformity of the products to the requirements of this European Standard and with the stated values (including classes) shall be demonstrated by:  Initial Type Testing (ITT) ; and  Factory Production Control (FPC) by the manufacturer, including product assessment. For the purposes of testing, the products may be grouped into families, where it is considered that the selected property/properties is/are common to all the products within that family. 5.2 Testing 5.2.1 Initial type testing (ITT) 5.2.1.1 General An initial type test is the complete set of tests or other procedures, determining the performance of samples of products representative of the product type. Initial type testing shall be performed to show conformity with this European Standard on first use of this European Standard for products being put onto the market and:  the beginning of the production with changes in new or modified product design, new raw material or supplier of the materials, if such a change is likely to alter the performance of the product;  the beginning of a new or modified method of production. In case of tests previously performed on the same products in accordance with the provisions of this standard (same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account (use of historical data).

5.2.1.3 "Deemed to satisfy" provisions and use of reference tabulated data In those cases where conformity with this European Standard is based on "deemed to satisfy" provisions or tabulated values, type testing shall be limited to the verification of whether the products meet the requirements to use those values, classes or levels, unless better values, classes or levels are being claimed. 5.2.1.4 Treatment of calculated values and design In some cases, the manufacturer will produce products in accordance with a design and/or calculations provided by a third party. In this case, verification will not be of the design or calculations themselves, but only of the fact that the products comply with the assumptions of the design and/or calculations. 5.2.1.5 Additional conformity procedure If required for special uses, the need for any additional requirements for conformity testing shall be specified at the time of order. If required by the order, conformity tests for additional characteristics as given in 4.1 g) shall be performed by the manufacturer. 5.2.2 Sampling, testing and conformity criteria 5.2.2.1 Sampling Initial type testing shall be performed on samples of products representative for the manufactured product type. The sampling shall be performed in accordance with the European Standards in Table 1. 5.2.2.2 Testing and conformity criteria The number of samples to be assessed shall be in accordance with Table 2.
