This European Standard was approved by CEN on 20 March 2019.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by

European foreword
This document (EN 10219-2:2019) has been prepared by Technical Committee CEN/TC 459 “ECISS -
European Committee for Iron and Steel Standardization” , the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by November 2019, and conflicting national standards
shall be withdrawn at the latest by November 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 10219-2:2006.
The main changes with respect to the previous edtion are listed below:
a) elliptical hollow sections were added;
b) Annex A concerning the additional tolerances for piling tubes was removed;
c) subclause 5.2 was added with one option;
d) in Table 3 the length tolerances for exact length were changed;
e) in 7.1 one paragraph was added;
f) standard was editorially revised.
This standard consists of the following parts:
— EN 10368, Steel structural hollow sections – General (Characteristics, evaluation of conformity and
marking) (in preparation)
— EN 10219-1, Cold formed welded steel structural hollow sections - Part 1: Technical delivery
conditions
— EN 10219-2, Cold formed welded steel structural hollow sections - Part 2: Tolerances, dimensions and
sectional properties
— EN 10219-3, Cold formed welded steel structural hollow sections - Part 3: Technical delivery
conditions for mechanical engineering purposes (in preparation)
It forms part of a series of standards on hollow sections together with EN 10210-1 to EN 10210-3.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.

Through its subcommittee SC 3 “Structural steels other than reinforcements” (secretariat: DIN)
1 Scope
This document specifies tolerances for cold formed welded circular, square, rectangular and elliptical
structural hollow sections, manufactured in wall thicknesses up to 40 mm, in the following size ranges:
— circular: Outside diameters up to 2 500 mm;
— square: Outside dimensions up to 500 mm × 500 mm;
— rectangular: Outside dimensions up to 500 mm × 300 mm;
— elliptical: Outside dimensions up to 480 mm × 240 mm.
The formulae for calculating sectional properties of sections manufactured to the dimensional
tolerances of this standard, to be used for the purposes of structural design, are given in Annex A.
Dimensions and sectional properties for a limited range of more common sizes are given in Annex B.
NOTE The designation of the sections' major axis (yy) and minor axis (zz) aligns with the axis designation
used for structural design in the structural Eurocodes.

NOTE This information is included in the list of information to be obtained by the manufacturer contained in
EN 10219-1.
5.2 Options
An option is specified in this part of EN 10219. In the event that the purchaser does not indicate a wish
to implement this at the time of enquiry and order, the manufacturer shall supply in accordance with
the basic specification.
Option 2.1 Out-of-roundness tolerances for diameter to thickness ratio exceeding 100 (see
Table 2, footnote a).
6 Tolerances
6.1 Tolerances shall not exceed the values given in Table 2 for shape and mass, Table 3 for external
