Execution of steel structures and aluminium structures - Part 1: Requirements for conformity assessment of structural components
This European Standard specifies general technical delivery conditions in terms of performance characteristics for structural steel and aluminium components placed on the market as construction products. The components may be used directly or for inclusion in construction works or as structural components in the form of kits. The Standard also specifies requirements to evaluation of conformity to the specified performance characteristics and for the test methods to be used.
This European Standard specifies requirements for steel components made from hot rolled, hot finished, welded and cold-formed products. It also applies to components made from cold formed members and sheeting.
This European Standard does not cover production of components for suspended ceilings, components of cast iron, components of cast steel and steel forging nor rails and sleepers for the use in railway systems.
This Standard does, however, cover fabrication of components from constituent products of cast and forged steel.
This Standard specifies requirements for aluminium components made from semi-finished products, cast or forged constituent materials and products.
NOTE For certain steel and aluminium products, particular specifications for performance and other requirements have been developed. The specifications can be issued as an EN or as clauses within an EN. An example is given in prEN for single wall steel chimneys and steel liners. Such specifications are meant to take precedence in case of non-compliance with the requirements of this standard.

EN 1090-1:2009 (E) 5 Introduction This harmonised European Standard is a part of a group of European standards dealing with design and manufacturing of load bearing components and structures made of steel or aluminium. This harmonised European Standard deals with provisions for conformity assessment of components which imply conformity to performance characteristics declared by the manufacturer of the components. The components have structural characteristics which make them fit for their particular use and function. The structural characteristics are governed by the design and the manufacture of the components. This harmonised European Standard does not contain rules for structural design and manufacture. Such rules are called up from the relevant parts of Eurocode for design requirements and from EN 1090-2 (steel) and EN 1090-3 (aluminium) for execution requirements. To use this harmonised European Standard for assessment and declaration of conformity of structural steel or aluminium components all relevant design and execution standards within the group need to be available. This harmonised European Standard has been prepared to satisfy Mandate M 120 – Structural metallic products and ancillaries (2/4) – issued by the European Commission. SIST EN 1090-1:2009
EN 1090-1:2009 (E) 6
1 Scope 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.

1 Scope
This European Standard specifies general technical delivery conditions in terms of performance characteristics for
structural steel and aluminium components placed on the market as construction products. The components may
be used directly or for inclusion in construction works or as structural components in the form of kits. The Standard
also specifies requirements to evaluation of conformity to the specified performance characteristics and for the test
methods to be used.
This European Standard specifies requirements for steel components made from hot rolled, hot finished, welded
and cold-formed products. It also applies to components made from cold formed members and sheeting.
This European Standard does not cover production of components for suspended ceilings, components of cast
iron, components of cast steel and steel forging nor rails and sleepers for the use in railway systems.
This Standard does, however, cover fabrication of components from constituent products of cast and forged steel.
This Standard specifies requirements for aluminium components made from semi-finished products, cast or forged
constituent materials and products.
NOTE For certain steel and aluminium products, particular specifications for performance and other requirements
have been developed. The specifications can be issued as an EN or as clauses within an EN. An example is given in
prEN for single wall steel chimneys and steel liners. Such specifications are meant to take precedence in case of non-
compliance with the requirements of this standard.

3 Terms and definitions
For the purposes of this European Standard, the following definitions apply:
component specification is a document or documents giving all necessary information and technical requirements
for manufacturing the structural component
constituent products are materials or products 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
design brief a document containing all information necessary to enable a structural design of the component,
considering its intended use.
load bearing capacity is one value or a set of values for the loads that can be carried by the component referring
respectively to a single type and direction of loading or to a set of loads in various directions of the loads, referring
to a defined level of resistance in accordance with EN 1990 and the relevant parts of EN 1993 or EN 1999.
structural components are 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 of for inclusion in a construction work
structural characteristics are properties of the component connected with its ability to function satisfactorily under
the influence of the actions it is subject to. In this European Standard the performance characteristics load bearing
capacity, fatigue strength and resistance to fire are defined as structural characteristics
structural kit consists of structural components to be assembled and installed on site; the assembled system
made from the structural kit is a “structure”

prEN 1090-1:2004 (E)
test method is the means to check that the mandated performance characteristics and the other characteristics of
the component comply with the values to be declared and any other required values. Test methods are used for
evaluation of conformity for characteristics such as material properties, geometry and structural characteristics.
Test methods include the determination of characteristics using physical testing, measurements and/or structural
calculations. In this standard the term “evaluation” is used as the common word for determination of these
characteristics.
NOTE There is presently no European Standard available on how to perform and evaluate results from structural
tests. The determination of structural characteristics will consequently relay on calculations in accordance with the
European standards for structural design referred to in this standard.

---------------------- Page: 11 ----------------------
prEN 1090-1:2004 (E)
For the purposes of evaluation, components or kits may be grouped into families if the selected property/properties
is/are common to all components within that family.
NOTE An example would be a set of components made from common constituent products but with different finished
shapes; in such cases the evaluation of characteristics that depend on the properties of the constituent products could
be undertaken on a common basis for the whole family of components.
6.2 Type evaluation
6.2.1 Initial type evaluation
6.2.1.1 General
An initial type evaluation is the complete set of tests or other procedures, determining the performance of samples
of products representative of the product type.
Initial type evaluation shall be performed to show conformity with this European Standard. An initial type evaluation
shall be performed
a) at the commencement of the production of a new component, new raw materials or new supplier of
constituent products (unless a component of the same family)
b) at the commencement of a new or modified method of production if this would affect a property subject to
evaluation.
In case of type evaluation on components or kits for which initial type evaluation in accordance with this standard
was already performed, type evaluation may be reduced:
c) if it has been established that the performance characteristics compared with the already evaluated
components or kits have not been affected, or
d) in accordance with the rules for grouping or direct extended application of test results.
If components are used whose characteristics have already been determined by the component manufacturer on
the basis of conformity with other product standards (e.g. manufacturing using constituent products declared as
conforming to a harmonized European specification), these characteristics need not be re-evaluated.
NOTE Products CE marked in accordance with appropriate harmonized European specifications (EN standards or
ETAs) may be presumed to have the characteristics stated with the CE marking, although this does not remove the
responsibility of the component manufacturer to ensure that the component has its declared properties.
6.2.1.2 Characteristics
The initial type evaluation of all characteristics for which the manufacturer provides a declaration shall be
performed using initial type testing, with the exceptions:
a) structural characteristics if these are evaluated by calculations;
b) reaction to fire of a component may be assessed indirectly by controlling the component’s constituent
products;
c) release of dangerous substances may be assessed indirectly by controlling the content of the component’s
constituent products;
d) durability of all characteristics, which is ensured by correct specification to avoid corrosion or to limit its
effect by a prescriptive requirement for corrosion protection of the components.

type, same characteristic(s), same test method, same sampling procedure, same system of attestation of
conformity etc) may be taken into account.
6.2.1.4 Use of structural calculations for conformity evaluation
If conformity to this standard is based on structural calculations, conformity evaluation of these characteristics is
limited to verification of the calculations made and that the components or kits corresponds to the component
specification
In cases where the manufacturer produces components in accordance with calculations and component
specifications provided by the purchaser, the conformity evaluation encompass a check of the components or kits
complying with the component specification.
NOTE It is presupposed that all manufacturing of components or kits is based on a component specification that
completely describes all requirements for the execution.
6.2.2 Further type evaluation
