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 12152:2023) 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be withdrawn at the latest by January 2024.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 12152:2002.
The main changes compared to the previous edition are listed below:
— modified the class "AE": added the declaration of the maximum test pressure;
— added a new classification of air permeability at negative pressure;
— added new symbols for the classification based on fixed joint length;
— editorial modifications to definitions, in order to make them compliant with the definitions of
EN 12153.
This document is part of a series of European Standards dedicated to curtain walling products and derives
from performance requirements.
This document forms part of a series of curtain walling standards as specified 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 specifies requirements and classification of air permeability of both fixed and openable
parts of curtain walling, under positive and negative static air pressure.
This document applies to curtain walling as specified in EN 13830.
NOTE This version EN 12152:2023 supersedes EN 12152:2002. Existing test results according to
EN 12152:2002 could be considered still valid compared with this version of EN 12152.

3.1
test pressure
differential air pressure between the two faces of the test specimen, expressed in pascal (Pa)
3.2
positive pressure
when the 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 included within the curtain walling, the length of the perimeter joint shall be
included in the calculation (see Figur
