For the purposes of this Directive, “construction product” means any product which is produced for<br />
incorporation in a permanent manner in construction works, including both buildings and civil<br />
engineering works. “Construction products” are hereinafter referred to as 'products'; construction<br />
works including both buildings and civil engineering works are hereinafter referred to as “Works”.<br />
Therefore the directive does not directly refer to the whole product, but to all those single elements<br />
(e.g. beams, connections, etc), that assembled realize the final work.<br />
Member States shall presume that products are fit for use if they enable works in which they are<br />
employed, provided the latter are properly designed and built, to satisfy the essential requirements<br />
referred to in Article 3 of the directive.<br />
The application of the directive indirectly implied a standardisation work for the production of sets<br />
of standards, within the field of application of the directive and supporting its essential<br />
requirements, as a mean to demonstrate conformity.<br />
In this framework the technical committee CEN TC 135 “Steel structure fabrication” is now<br />
preparing the standard (the name will be EN 1090) harmonized to the 89/106/CE directive. This<br />
standard is made of 3 parts:<br />
- Part 1: Steel and aluminium structural components - General delivery conditions<br />
- Part 2: Technical requirements for the execution of steel structures<br />
- Part 3: Technical requirements for the execution of aluminium structures<br />
8.2 EN 1090 – 1: Steel and aluminium structural components - General<br />
delivery conditions<br />
This European Standard specifies general technical delivery conditions in terms of performance<br />
characteristics for structural steel and aluminium components placed on the market as construction<br />
products. The components may be used directly or for inclusion in construction works or as<br />
structural components in the form of kits.<br />
The Standard also specifies requirements for the evaluation of conformity to the specified<br />
performance characteristics and for the test methods to be used.<br />
8.2.1 Requirements for the design of structures.<br />
Structural characteristics of a component covered in this Standard refer to its load bearing<br />
capacity, fatigue strength and resistance to fire 11 .<br />
11 Those structural characteristic shall refer to National Determined Parameters (referred as NPD in the<br />
standard), that are parameters specified in the National Annex to the relevant Eurocode, defined by the<br />
member states<br />
