The EN 15088 standard specifies the requirements for semi-finished and cast products of aluminium and aluminium alloys used in load-bearing structural construction works. It covers the scope of construction works, buildings, civil engineering works. It also specifies the requirements for conformity assessment and test methods to be used, and the technical delivery conditions. It has been developed to ensure that structural elements made of aluminium are safe, efficient and long-lasting, especially in the construction sector. The EN 15088 standard does not apply to products manufactured after machine operations or assembly processes (e.g. screwing together elements, welding). The EN 15088 Certificate is an important document that shows that aluminium construction materials comply with European Union standards. This document ensures that the products carry theCE mark in order to be used in the European market.

Alloy and Heat Treatment Selection: In the manufacturing of aluminum structures, the alloy and heat treatment should be suitable for the functional and usage requirements specified in the scope. Material selection should be made in accordance with the relevant sections of EN pr1999 and EN 1090-3, including durability considerations.
Mechanical Properties of Products under Cyclic Loads / Fatigue Strengths: Materials should be classified separately for each case based on their intended use:
Class I: The product is not subjected to fatigue.
Class II: The product is subjected to fatigue, and fatigue properties are specified in prEN 1999-1-3.
Class III: The product is subjected to fatigue, but fatigue properties are not specified in prEN 1999-1-3.
Regarding restrictions to avoid substances subject to regulations, the manufacturer must ensure that no harmful emissions/release of substances exceeding the legally permitted levels in the member state of the target country will affect health or the environment. Aluminum scrap must comply with EN 13920-1.
Durability: The natural corrosion resistance of aluminum and its alloys generally guarantees durability for a reasonable economic service life. For exceptional atmospheric conditions or harsh use, material selection should be made considering all relevant requirements. The durability of aluminum and aluminum alloys should be declared according to prEN 1999-1-1 Table 3.1a, Table 3.1b, or prEN 1999-1-4 Table 3.1.
The weldability of aluminum and aluminum alloys should be declared according to prEN 1999-1-1 Annex C, Table C.1 and Table C.2.
Requirements and test methods for mechanical properties, dimensions, and tolerances on shape should be as specified in the standards provided in Table 1.
Table 1. Requirements and General Provisions
The main areas of focus of EN 15088 are as follows:
1.Aluminum Structures: It establishes the rules for the design of structural components made of aluminum. This aims to provide both aesthetically and structurally safe, durable, and functional solutions.
2.Load Carrying Capacity: It provides information on how much load aluminum components can carry, how these loads are distributed, and the risk of component failure or deformation.
3.Integrity and Durability: It defines the design and manufacturing criteria required for aluminum components to last over time. This ensures that the component remains robust, even in challenging conditions like outdoor use.
4.Assembly and Manufacturing: It offers guidance on how aluminum components should be manufactured and assembled.
5.Testing Methods: It covers the tests that need to be conducted to verify the accuracy, safety, and durability of these structural elements.
Factory Production Control System (FPC)
The manufacturing organization must establish a Factory Production Control System (FPC system) in accordance with EN 15088 and continuously apply this system.
The FPC system should include procedures, regular inspections, tests, and/or evaluations, and these results must be used for controlling raw materials and other incoming materials, components, equipment, the manufacturing process, and the final product. Records must be readable, easily identifiable, and accessible. It is a system that combines all necessary measures to ensure and control compliance with the operational techniques and the declared performance characteristics of the product.
A FPC System that is produced in accordance with the requirements of EN ISO 9001 and specifically tailored to the requirements of this European Standard is considered to meet the requirements of the standard. The results of inspections, tests, or evaluations should be recorded, and any actions required should also be documented. In case control values or criteria are not met, actions taken should be recorded and stored for the duration specified in the manufacturer’s FPC procedures.
