This European Standard was approved by CEN on 5 June 2023.

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
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

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be withdrawn at the latest by January 2024.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
overall area
sum of the areas of all the faces measured parallel to all fixed and openable panels (see Figure 2)
Note 1 to entry: It shall be expressed in m .
Note 2 to entry: Profiles for mounting the specimen in the test stand shall not be considered.
