European foreword
This document (EN 12153:2023) has been prepared by Technical Committee CEN/TC 33 “Doors,
windows, shutters, building hardware and curtain walling”, 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 January 2024, and conflicting national standards shall
be withdrawn at the latest by January 2024.
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 12153:2000.
The main changes compared to the previous edition are listed below:
— added a new test of air permeability at negative pressure and re-adapted the details of test report
accordingly;
— editorial modifications to definitions, in order to make them compliant with the definitions of
EN 12152.
This document contains a bibliography which provides for the inclusion of additional information in the
expression of the test results.
This document is part of a series of European Standards dedicated to curtain walling products.
This document forms part of a series of curtain walling performance requirements as defined in the
product standard EN 13830.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
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, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document defines the method to be used to determine the air permeability of curtain walling, both
its fixed and openable parts. It describes how the specimen shall be tested under positive and negative
air pressure.
This document applies to any curtain walling product as defined in EN 13830.
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 terms and definitions given in EN 13119 and the following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
3.1
test pressure
differential pressure between the two faces of the test specimen, expressed in pascals (Pa)
3.2
positive pressure
when outer face is subjected to higher air pressure than the inner face
3.3
negative pressure
when the outer face is subjected to lower air pressure than the inner face
3.4
air permeability
passage of air through the construction of the curtain walling when subjected to air pressure
Note 1 to entry: The volume being expressed as a rate in cubic metres per hour (m /h), this rate being related to
the overall area of the curtain walling. Alternatively, the rate can be related to the metre length of joint.
3.5
fixed joint
all joints except those between openable parts of the curtain wall (see Figure 3)
3.6
fixed joint length
sum of the length of all fixed joints within the curtain walling measured along the line of the air
seal/barrier
Note 1 to entry: Where a window is incorporated in the specimen it shall be considered as a panel for the purpose
of the fixed joint calculation (see lines 1 in Figure 3).
3.7
openable joint length
perimeters of all moving casement or sash, in accordance with EN 12207
3.8

5 Principle
Application of increasing and decreasing pressure steps (positive or negative) with measurements of air
flow at each test pressure.
6 Apparatus
A chamber with an opening into which the test specimen can be fitted. This chamber shall be of sufficient
strength and rigidity to withstand the test pressures likely to be imposed during the tests. It shall not
deflect under test pressure to any extent which would affect the performance of the test specimen (see
Figure 1).
Adequately representative structural supports shall be provided to which the specimen shall be attached
in accordance with the conditions of use in the works (see also 7.1).
The chamber shall be constructed so that the air permeability through it, at pressures up to the maximum
test pressure, does not exceed the permissible air permeability through the specimen at the same
pressure.
A means for applying controlled positive (or negative) test pressures to the test specimen.
A means by which rapidly controlled changes of positive (or negative) test pressures may be produced
within defined limits.
A means of measuring the air flow into the chamber within an accuracy of ± 5 % in order to enable the
quantity of air permeability through the specimen to be assessed within an accuracy of 10 % of the
permissible air permeability through the specimen.
A means of measuring the positive (or negative) test pressures, steady or fluctuating, calibrated within
an accuracy of ± 5 %.
A temporary means of sealing all joints of the specimen during the determination of test chamber
leakages.
7 Test methods
7.1 Test specimen
The specimen shall be submitted in a fully operable condition, ready for use. It shall be supplied in a
suitable manner for fixing onto a test chamber. The test specimen should be either representative
according to EN 13830, or not be less than two typical units wide and shall be sufficient to provide full
loading on at least one typical vertical joint or framing member or both. The specimen shall not obtain
additional stiffness from the test chamber. The height shall not be less than the full distance between the
curtain wall’s point of connection to the building structure.
For custom designed curtain walls or special elements, the specimen shall be a size which is adequate to
demonstrate its compliance with the specified requirements.
All parts of the specimen shall be full size, using the same materials, details, methods of construction and
fixing as intended for use in the works. Conditions for connection to the structural support shall simulate
those in the works as accurately as possible (see also Clause 6).
This document does not apply to the perimeter joints between the curtain walling and the test chamber,
or to the joints between the curtain walling and the building construction.
7.2 Test preparation
Build the test specimen into the test chamber.
Fix true to the normal attitude of use in both directions, level, square and without visible twist or bend as
a result of the application of fixing devices.
Remove all transport blocks, bracings or packings and protective wrappings.
Tape all openable joints to prevent air infiltration.
Tape seal any ventilation devices, where these may occur.
Ensure any leakage through all points, including frame joints, is readily detectable.
Ensure all joints between the test specimen and the test chamber are sealed.
Ensure the specimen is clean prior to commencing the test sequence.
