This European Standard was approved by CEN on 11 March 2008.
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 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 Management Centre has the same status as the
official versions.

Foreword
This document (EN 15423:2008) has been prepared by Technical Committee CEN/TC 156 “Ventilation for
buildings”, the secretariat of which is held by BSI.
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text or by endorsement, at the latest by November 2008, and conflicting national standards shall be withdrawn
at the latest by November 2008.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.
1 Scope
This document gives guidance for system designers, installers, commissioners and maintenance teams on the
incorporation of protective measures for air distribution systems including dual purpose systems for smoke
and heat exhaust systems within buildings, to prevent the initiation and the spread of fire, smoke and other by-
products of combustion.
This document intends to only support any national (building) regulations, which are the basis of any design of
a building or parts of it. It is up to the designer to enquire about the suitability (in particular in legal terms) of a
specific solution given in this document (e.g. although “dual purpose systems” are covered in this document,
they may not be permitted in some Member States or only in certain types of buildings).
This document applies to all air distribution systems including dual purpose systems (except systems only
dedicated to smoke exhaust systems, which are dealt in other European standards) including technical rooms
or spaces for the installation of devices to assist in ventilation of a building (e.g. distance of storage of
combustible materials to devices and not the fire resistance of the building structure), penetrations, and
following components/products used in the system like:
 inlet/outlet louvres;
 fans not exposed / exposed to the smoke;
 air control dampers;
 ducts;
 fire control dampers;
 air terminal devices;
 anchors and supports;
 duct fittings;
 control panels;
 cables and connections;
 air handling units;
 air filters;
 sound attenuators;
 heat exchangers.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 12792:2003, together with
the following apply.

are located
3.2
support
device for a system component, e.g. fire damper, silencer, etc. to bear a load
3.3
inlet/outlet louvre
device, consisting of an assembly of parallel sloping vanes, intended to permit the passage of air, while
providing a measure of protection against environmental influences
[EN 12792:2003, Table 1, number 242]
3.4
