EN 15088:2005 (E) 3 Foreword This document (EN 15088:2005) has been prepared by Technical Committee CEN/TC 132 “Aluminium and aluminium alloys”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. This document has been prepared under the mandate M 120 given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Construction Products Directive CPD 89/106/EEC. For relationship with EU Construction Products Directive CPD, see informative Annex ZA, which is an integral part of this document and which it becomes a harmonized European Standard. Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 14 "General Support" to prepare the following standard : EN 15088 "Aluminium and aluminium alloys — Structural products for construction works — Technical conditions for inspection and delivery". According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 15088:2005 (E) 4 Introduction This European Standard is an "umbrella" standard which gives the regulatory requirements to enable manufacturers or their agents to affix CE marking, in accordance with Directive 89/106/EEC (Construction Products Directive CPD) to products within the scope of this European Standard. It is intended to be used in conjunction with other referenced material/ product standards (see Figure 1). A manufacturer who has no knowledge of its final destination may sell a product to a stockist. It is the responsibility of the manufacturer, that the product complies with the conditions of CE marking for the stated intended use included as part of the CE marking. If the stockist resells the product for another intended use or changes the product in a way, he in effect becomes a new manufacturer. Consequently, he becomes responsible for the appropriate CE marking of the product that he places on the market. Therefore, irrespective of current terminology in terms of regulatory marking there will only ever be two parties, the seller (the manufacturer) and the buyer (the purchaser). Products CE marked in accordance with this harmonized European Standard can be presumed to have the performances stated with the CE marking. This does not replace the responsibility on the designer to ensure that the final structural product made of aluminium as a whole is correctly designed and its components meet the necessary performance values depending on the design, especially in view of fatigue design.

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).
EN 15088:2005 (E) 13 In case of type testing on products for which initial type testing in accordance with this European Standard was already performed, type testing may be reduced if it has been established that the performance characteristics compared with the already tested products have not been affected. 5.2.1.2 Characteristics All characteristics in 4.3 shall be subject to initial type testing with the following exceptions : release of regulated substances may be assessed indirectly by controlling the content of the substances concerned; prescriptive requirement on corrosion protection.
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.
