Introduction
This document specifies requirements for the use of reclaimed structural components in steel structures
designed according to the EN 1993 series and executed according to EN 1090-2.
This document presupposes that the work is carried out with the necessary knowledge and adequate
equipment and resources to perform the work in accordance with the execution specification and the
requirements of this document.
1 Scope
This document gives complementary provisions to EN 1090-2 for the use of reclaimed structural
components for the execution of steel structures to EXC1, EXC2 and EXC3 (see EN 1090-2). The provisions
apply to products used in structures to be designed (see EN 1993-1-1) for quasi-static loading and not
subject to fatigue loading.
NOTE 1 The conditions of implementation of this document in a country are at the discretion of the national
Standardization Body. Non contradictory requirements, e.g. with regard to seismic loading, can be added.
This document gives requirements for the reusability assessment of reclaimed structural components
and constituent products.
This document also gives requirements for the quality assessment of plates, hot rolled profiles and hot
finished or cold formed hollow sections in carbon steel used as constituent products (see EN 1090-2).
This includes the declaration of mechanical and geometrical properties as well as weldability.
NOTE 2 The properties to be declared are those listed as required relevant properties to be specified as described
in EN 1090-2:2018+A1:2024, Clause 5.1.
The requirements on quality assessment in this document also apply to the assessment of the mechanical
and geometrical properties as well as weldability of fabricated products. The recommendations for the
assessment of connections however, and in particular of welds, are non exhaustive and only informative.
This document does not apply to cold-formed structural steel sections and sheeting as described in
EN 1090-4, or mechanical fasteners.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
constituent product
material or product used in manufacturing with properties which enter into structural calculations or
otherwise relate to the mechanical resistance and stability of works and parts thereof, and/or their fire
resistance, including aspects of durability and serviceability
3.2
fabricated structural component
structural component made of one or more constituent products including workmanship
3.3
reclaimed structural component
structural component which is salvaged from a donor structure and is intended to be used again for
fabrication and/or erection of a recipient structure
3.4
provenance
basic information on the previous use of a reclaimed structural component
3.5
type 1 structural steel
structural steel material produced in or after 1970 and with a set of relevant properties, including their
variations, equivalent to one of the standard structural steel materials listed in EN 1993-1-1
3.6
type 2 structural steel
structural steel material produced before 1970 and with relevant properties that might significantly
deviate from those of standard structural steel materials listed in EN 1993-1-1
3.7
test unit
group of individual reclaimed structural components with identical geometrical properties and same
function for which relevant properties can be derived from testing a single or a few representative
member(s)
3.8
location of a component
location of a reclaimed component in the donor structure (e.g. floor plan, façade)
3.9
function of a component
description of a reclaimed component indicating the major loads the component was subjected to in the
donor structure (e.g. floor beam, column)
4 Deconstruction
An identification system shall be established prior to deconstruction in order to ensure that reclaimed
structural components can be traced to their provenance, including function and location.
The information to be included in the identification system with regard to location and function of the
reclaimed structural components should be consistent with the required information for grouping the
components in test units, see 5.3.4.2.
NOTE An individual identification system by means of which each reclaimed structural component can be
traced to its exact location in the donor structure provides the highest level of detailed information and allows more
flexibility in later stages of the assessment process. A less detailed system can be justified economically where
components are initially identified in groups, for instance by floor.
Deconstruction shall follow an established deconstruction plan to ensure stability at all times, and
minimize damage.
Disassembled structural components intended for reuse shall be handled and stored in such a way that
the likelihood of damage is minimized, see EN 1090-2:2018+A1:2024, 6.3 and 9.6.3.
5 Assessment of reclaimed structural components
5.1 General
The suitability of reclaimed structural components for reuse shall first be established based on
information on previous use and condition evaluation, see 5.2. A comprehensive quality assessment shall
then be performed in order to determine or confirm relevant properties, see 5.3.
The extent and type of testing required for the quality assessment shall depend on the amount of
information available and outcome of the reusability assessment, see 5.2.
The reusability assessment should be made in the early stages of the reclamation process, ideally before
deconstruction, in order to evaluate the economic and technical feasibility of reuse.
The reusability and quality assessments, see 5.2 and 5.3, shall be documented in an inspection and test
record, see 5.4.
5.2 Reusability assessment
5.2.1 Data collection
The following information about the structural components to be reused should be collected, analysed
and recorded, if available:
a) Date and place of construction of the original building;
b) Information on fabricator, erector, designer, architect and other actors;
c) Drawings, models, photographic evidence for the as built structure;
d) Inspection documents, e.g. according to EN 10204 or similar standard in use at the time;
e) Information about the design such as calculation notes, loading history;
f) Building Owner’s manual;
g) Operation and maintenance manual;
h) Inspection and maintenance records;
i) Records of interventions (e.g. expansions, modifications);
j) Records from any possible incident (e.g. fire, earthquake).
This information shall be used as basis for the choice of testing protocol, see 5.3.4.
At least the following information shall be recorded and included in the inspection and test record:
a) A description of the donor structure including its use and geographical location;
b) The age of the donor structure which may be obtained from records (e.g. building permit) or
local/anecdotal information;
c) A listing of the structural components including their location and function;
d) The results of a condition evaluation, see 5.2.2.
5.2.2 Condition evaluation
All structural components intended for reuse shall be subjected to visual inspection in order to identify
any:
a) Global deformations indicating plastification;
b) Signs of direct exposure to high temperatures (e.g. soot, burnt or blistered paint), or;
c) Local damages, inclusive plastic deformations, and reduced cross sections (e.g. through holes,
openings, cracks or excessive corrosion).
Structural components which are excessively deformed should not be reused. However, some deviation
from the essential tolerances in EN 1090-2 may be accepted if it is correctly declared, see 5.3.2.
Structural components which have been directly exposed to fire but satisfy the relevant essential
tolerances in EN 1090-2, may be reused if their yield strength does not exceed 355 MPa.
All surfaces should be visually inspected to ensure that there is no significant loss of section due to
corrosion as compared to the measured section.
Local damages and/or reduced cross sections should be dealt with in one of the following ways:
a) the whole structural component is marked as unsuitable for use according to EN 1090-2, or;
b) the weakened part of the component is marked and removed at a later stage, allowing for reuse of a
structural component with unreduced cross section, or;
c) the actual section properties are measured and documented, see 5.3.2, in order to be used for design
purpose, or;
d) the damaged area is repaired, see 7.
In the case of structural hollow sections, the external surface of the weld seam should be visually
inspected to confirm that there are no surface breaking defects. If the components are not made of type 1
structural steel, all weld seams should be entirely inspected by magnetic particle inspection or ultrasonic
testing.
Repaired components should be considered as fabricated products.
NOTE The assessment of coatings is outside the scope of this document as it is expected that existing coatings
on constituent products will generally be removed as part of the fabrication process. In the case of fabricated
structural components however it might be of interest to reuse the structural components in their current condition
and thus assess the condition of coatings. General recommendations to this purpose are given in the informative
Annex B of this document.
5.3 Quality assessment
5.3.1 General
Reclaimed structural components which have passed the reusability assessment shall be subjected to a
quality assessment in order to evaluate or confirm their relevant properties.
Where reclaimed structural components are to be used as constituent products the relevant properties
to be specified shall be in accordance with EN 1090-2:2018+A1:2024, Clause 5.1:
a) Yield (f = R ) and tensile (f = R ) strength;
y eH u m
b) Elongation;
c) Tolerances on dimensions and shape;
d) Heat treatment delivery condition, and;
e) Weldability.
NOTE 1 Heat treatment delivery condition is only relevant for hollow sections.
Detailed requirements on the evaluation of each of these properties are given in 5.3.2 to 5.3.4.
Weldability should be specified as a declaration of the chemical composition in sufficient detail for the
carbon equivalent to be calculated.
NOTE 2 The chemical composition of type 2 structural steel is likely to vary from current steelwork. The
responsible welding coordinator can wish to undertake welding trials and increase pre- and post-weld testing.
If the reclaimed structural components are fabricated structural components, the relevant properties of
all their individual parts shall be assessed and the quality of workmanship shall be in accordance with the
requirements of EN 1090-2.
NOTE 3 The assessment of fabricated structural components presents challenges, particularly with regard to
testing of welds, for which there are no practical and widely accepted solutions. General and non-exhaustive
recommendations are given in the informative Annex C of this document.
5.3.2 Geometrical properties
The cross-sectional dimensions and tolerances of all members of the test unit shall be measured and
declared.
The geometrical properties may be declared directly or as a nominal section designation.
If the dimensions are declared directly for all members of a test unit, the average measurements and their
coefficients of variation should be declared.
NOTE 1 For the most common shapes, relevant standards are provided in EN 1090-2:2018+A1:2024, Tables 2, 3
and 4. Even alternative shapes can occur for which other standards in use at the time are relevant.
If the dimensions are declared as a nominal section designation, the measured values shall meet all the
requirements on dimensions and tolerances in the relevant product standard.
All reclaimed structural components should meet the relevant essential tolerances according to
EN 1090-2 and any project specific functional tolerances.
Alternatively, reclaimed structural components which do not meet the tolerance requirements in
EN 1090-2 may still be reused if the deviations are documented so that they can be accounted for in the
structural design.
NOTE 2 The relevant deviations depend on the type of product and some guidance is given in the relevant part
of EN 1090-2.
Possible holes or damages which are not repaired should be documented so that they can be accounted
for in the structural design.
5.3.3 Heat treatment delivery condition
Reclaimed hollow sections shall be assumed to be cold formed according to EN 10219-1 and EN 10219-2
if no clearer information is available.
5.3.4 Testing protocols
5.3.4.1 General
Four testing protocols, A to D, are described in this document. Recommendations for the choice of a
specific protocol are given below and illustrated in Figure 1.
If the donor structure was executed according to EN 1090-2 and the grades and/or qualities of the
structural components can be identified, original inspection documents according to EN 10204 may be
used to declare the properties of the component, see testing protocol A in 5.3.4.3.
Structural components which have a known provenance should be grouped in test units according to
5.3.4.2.
The provenance should be considered as known when at least the geographical location, building year
and former function of the components are known, see 5.2.1
The measurements undertaken for one or a few representative members of a test unit may be the basis
of the declared properties for all members of that test unit, see 5.3.4.4 and 5.3.4.5.
A distinction should be made between type 1 and type 2 structural steel.
Type 1 structural steel may be expected to have mechanical properties and weldability similar to steel
grades according to European standards listed in Clause 5.3 of EN 1090-2:2018+A1:2024. The variability
of their mechanical properties may be assumed to be according to Annex E of EN 1993-1-1.
The mechanical properties of type 1 structural steel may be determined by testing a single representative
sample according to testing protocol B in 5.3.4.4.
For type 2 structural steel, the variability of the properties cannot be reliably assumed and more tests
should be undertaken as well as a statistical analysis of the results, according to protocol C in 5.3.4.5.
Structural components of unknown provenance shall not be grouped in test units and comprehensive
testing is required, according to protocol D in 5.3.4.6.
Figure 1 — Flowchart for the choice of testing protocol
5.3.4.2 Test units
Reclaimed structural components may be grouped in test units as follows:
a) They are reclaimed from the same donor structure;
b) They had the same structural function (e.g. floor beam, column);
c) They have the same nominal cross-sectional dimensions.
A test unit should not exceed a total weight of 20 tonnes.
An identification system shall be established for the test units and their members in order to ensure that
each component can be tracked and associated to its test unit as well as its individual test results
throughout the quality assessment process.
If inspection documents are not available, non-destructive hardness testing according to 6.1.1 should be
undertaken for all members of a test unit.
The acceptance criteria for the results of non-destructive testing within a test unit, and a procedure for
handling of nonconformities shall be defined before testing and documented.
NOTE The acceptance criteria are closely related to the testing method and the results of procedure tests, see
6.1.1, and many statistical tools are available for testing the normality of results for instance. The acceptance criteria
are not critical for the safety of the quality assessment. Sufficient safety is achieved by following the requirements
in this Technical Specification for the selection of the representative member(s) of a test unit.
5.3.4.3 Protocol A – Documentation available (Type 1 structural steel with original inspection
documents)
Strength, elongation, impact toughness, chemical composition and actual optional properties should be
declared based on the specific test results in original inspection documents according to EN 10204, i.e.
inspection document 3.1 or 3.2.
If several inspection documents with varying test results are available for different members of a test unit,
all results should meet all requirements for the same material type and all inspections documents should
be collected.
5.3.4.4 Protocol B – Single sample DT (Type 1 structural steel with known provenance)
5.3.4.4.1 General
The member of the test unit with the lowest hardness value should be taken as the representative member
of that test unit and tested with destructive techniques, see 6.2.
The test results should be interpreted according to and fulfil the requirements given in 5.3.4.4.2 to
5.3.4.4.4.
5.3.4.4.2 Strength and ductility
The representative member of the test unit shall be submitted to tensile testing according to 6.2.2, in
order to determine the yield and ultimate tensile strength (ReH and Rm) as well as the elongation at failure
(A).
The reclaimed steel material shall satisfy the ductility requirements in EN 1993-1-1.
NOTE 1 The ductility requirements in EN 1993-1-1 are an NDP and can vary from country to country.
The characteristic values of yield and ultimate tensile strength may be determined from the test results
using EN 1990.
NOTE 2 The determination of these properties is in accordance with Clause D.7: Design assisted by testing of
EN 1990:2023.
The coefficient of variation for yield and ultimate tensile strength may be obtained from EN 1993-1-1.
NOTE 3 EN 1993-1-1:2022, Annex E proposes values for the coefficient of variation of yield strength and ultimate
tensile strength.
Alternatively, the yield and ultimate tensile strength may be declared by referring to an equivalent steel
grade for which the measured yield and ultimate tensile strength satisfy the criteria in Table 1.

NOTE The minimum yield and ultimate tensile strength in Table 1 are the 5 %-fractiles assuming material
properties according to EN 1993-1-1:2022, Annex E.
5.3.4.4.3 Impact toughness
If required, the representative member of the test unit or any other randomly chosen member should be
submitted to impact testing according to 6.2.3.
The impact toughness may be declared as an equivalent steel quality (subgrade) defined in the relevant
product standard. In that case, the results of impact testing shall satisfy all the criteria specified in the
product standard for that quality.
Conservatively, and in the absence of testing, quality JR may be assumed for type 1 structural steel.
5.3.4.4.4 Chemical composition
The representative member of the test unit shall be submitted to an analysis of its chemical composition
according to 6.2.4.
The mass concentrations of elements specified in 6.2.4 as well as the Carbon Equivalent Value (CEV) shall
be declared.
