subsequent heat treatment above 580 °C to obtain equivalent metallurgical conditions to those
obtained in the hot formed product
3.1.2
cold forming
process where the forming to final shape of the welded hollow section is carried out at ambient
temperature
Note 1 to entry: Circular hollow sections produced from normalized strip with a normalized weld seam and
with a cold forming ratio of D/T ≥ 20 may be classified as hot-finished hollow sections.
3.1.3
normalizing rolling

material condition equivalent to that obtained after normalizing so that the specified values of the
mechanical properties are retained even after subsequent normalizing
3.1.4
thermomechanical rolling
simultaneously performed forming process and heat treatment in which the final deformation from
round to rectangular/square/elliptical hollow sections is carried out in a certain temperature range
above 580 °C leading to a material condition with certain properties which cannot be achieved or
repeated by heat treatment alone
Note 1 to entry: Thermomechanical rolling leading to the delivery condition M can include processes with an
increasing cooling rate with or without tempering including self-tempering but excluding direct quenching and
quenching and tempering.
Note 2 to entry: In some publications the word TMCP (Thermomechanical Control Process) is also used.
3.1.5
steel with improved atmospheric corrosion resistance
steel in which a certain number of alloying elements has been added in order to increase its resistance
to atmospheric corrosion, by forming an auto-protective oxide layer on the base metal under the
influence of weather conditions

Note 2 to entry: Additional information for the use of steel with improved atmospheric corrosion resistance is
given in prEN 10210-2:2016, Annex E.
3.1.6
quenching and tempering
process which consists of the following two steps:
— first quenching, where the steel is heated up above AC3 temperature and then rapidly cooled down
in liquids to create a process specific grain structure;
— afterwards tempering, during which the steel is heated up to a certain temperature to adjust the
desired properties and cooled down in air afterwards
3.1.7
fine grain steel
steels with fine grain structure with an equivalent index of ferritic grain size ≥ 6
Note 1 to entry: For the determination of grain sizes except for +QT steels, see EN ISO 643.
3.2 Symbols
For the purposes of this document, the symbols defined in EN 10266:2003 apply.
4 Product characteristics
4.1 Chemical composition (durability)
The chemical composition determined by the cast analysis and reported by the steel producer shall
comply to the requirements given in prEN 10210-2:2016, Tables A.1, B.1, C.1, D.1 or E.1.
4.2 Mechanical properties (yield strength, tensile strength, elongation and impact
strength)
4.2.1 Under the inspection and testing conditions as specified in prEN 10210-2:2016, Clause 8 and in
the delivery condition as specified in prEN 10210-2:2016, 6.5 the mechanical properties of the finished
hollow section shall conform to the relevant requirements of prEN 10210-2:2016, Tables A.3, B.3, B.4,
C.3, C.4, D.3, D.4 and E.3.
NOTE Any heat treatment at more than 580 °C may lead to a reduction in the mechanical properties of TMCR
sections and also hot finished sections not processed in the normalizing temperature range.
4.2.2 For impact tests, standard Charpy-V-notch test pieces in accordance with EN ISO 148-1 shall be
used. If the nominal product thickness is not sufficient for the preparation of standard test pieces, the
test shall be carried out using test pieces of width less than 10 mm, but not less than 5 mm. The
minimum average values given in prEN 10210-2:2016, Tables A.3, B.4, C.4, D.4 and E.3 shall be reduced
in direct proportion to the actual width of the test piece compared to that of the standard test piece.
Impact tests are not required for specified thicknesses ≤ 6,3 mm.
NOTE If a Charpy test is performed at a lower temperature than specified in the standard and the impact
energy values obtained meet the requirements at the higher temperature, then the material is deemed to conform
to the standard and the test need not be repeated at the higher temperature.

4.3 Weldability
The steels specified in this European Standard are weldable as given in prEN 10210-2:2016, Annexes A
to E. General requirements for welding of the products in accordance with this European Standard are
given in EN 1011-1 and EN 1011-2.
The maximum carbon equivalent value (CEV) for all grades, based on the cast analyses, given in
prEN 10210-2:2016, Tables A.2, B.2, C.2, D.2 and E.2 shall apply.
When determining the CEV, the following formula of the International Institute of Welding (IIW) shall
be used:
Mn Cr++Mo V Ni+Cu

CEV=C++ +
6 5 15
NOTE 1 When welding hollow sections, as product thickness, strength level and CEV increase, the occurrence
of cold cracking in the welded zone forms the main risk. Cold cracking is caused by a combination of the following
factors:
— high levels of diffusible hydrogen in the weld metal;
— a brittle structure in the heat affected zone;
— significant tensile stress concentrations in the welded joint.
NOTE 2 By using guidelines, specified for example in EN 1011-1, EN 1011-2 or any other relevant welding
standard, the recommended welding conditions and the various welding ranges for the steel grades can be
determined. These will vary depending on the product thickness, the applied welding energy, the design
requirements, the electrode efficiency, the welding process and the weld metal properties.
4.4 Tolerances on dimensions and shape
Tolerances of dimensions and shape shall be as specified in prEN 10210-3.
4.5 Dangerous substances
National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this standard are placed on those markets.
In the absence of European harmonized test methods, verification and declaration on release/content
should be done taking into account national provisions in the place of use.
NOTE An informative database covering European and national provisions on dangerous substances is
available at the Construction web site on EUROPA accessed through:
http://ec.europa.eu/enterprise/construction/cpd-ds/.
5 Testing, assessment and sampling methods

value. The choice of a suitable physical or chemical analytical method for the analysis shall be at the
discretion of the manufacturer.
5.2 Mechanical properties
5.2.1 Frequency of tests for the mechanical properties

(unless a member of the same product range), or
— at the beginning of a new or modified method of production (where this may affect the stated
properties), or it shall be repeated for the appropriate characteristic(s), whenever a change occurs
in the hot finished structural steel hollow section design, in the raw material, or in the method of
production process (subject to the definition of a family), which would affect significantly one or
more of the characteristics.
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same
AVCP system on the same product or products of similar design, construction and functionality, such
that the results are applicable to the product in question.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for that same characteristics for all products within that same family.
NOTE 1 Products may be grouped in different families for different characteristics.
NOTE 2 Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
Products bearing regulatory marking in accordance with appropriate harmonized European
specifications may be presumed to have the performances declared in the DoP, although this does not
replace the responsibility on the hot finished structural steel hollow sections manufacturer to ensure
that hot finished structural hollow steel sections as a whole is correctly manufactured.
6.2.2 Test samples, testing and compliance criteria
The number of samples of hot finished structural steel hollow sections to be tested/assessed shall be in
accordance with Table 1.
