This European Standard specifies requirements for conformity assessment of performance characteristics for
structural steel and aluminium components as well as for kits placed on the market as construction products.
The conformity assessment covers the manufacturing characteristics, and where appropriate the structural
design characteristics.
This European Standard covers also the conformity assessment of steel components used in composite steel
and concrete structures.
The components can be used directly or in construction works or as structural components in the form of kits.
This European Standard applies to series and non-series structural components including kits.
The components can be made of hot rolled or cold formed constituent products or constituent products
produced with other technologies. They may be produced of sections/profiles with various shapes, flat
products (plates, sheet, strip), bars, castings, forgings made of steel and aluminium materials, unprotected or
protected against corrosion by coating or other surface treatment, e.g. anodising of aluminium.
This European Standard covers structural cold formed members and sheeting as defined in EN 1993-1-3 and
EN 1999-1-4.
This European Standard does not cover conformity assessment of components for suspended ceilings, rails
or sleepers for use in railway systems.
NOTE For certain steel and aluminium components, particular specifications for performance and other requirements
have been developed. The particular specifications may be issued as an EN or as Clauses within an EN. An example is
given in EN 13084-7 for single wall steel chimneys and steel liners. Such particular specifications will take precedence in
case of non-compliance with the requirements of this European Standard.
