Foreword
This document (prEN 1366-2:2010) has been prepared by Technical Committee CEN/TC 127 “Fire safety in
buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1366-2:1999.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of 89/106/EEC.
EN 1366 ‘Fire resistance tests for service installations’ consists of the following

Introduction
The purpose of the test is to evaluate the ability of a fire damper to prevent fire and smoke spreading from one
fire compartment to another through the air ductwork system which may penetrate fire separating walls and
floors.
The fire damper is attached (directly or remotely via a section of ducting), to a fire separating element in a
manner representative of practice. Tests are performed starting with the fire damper in the open position to
expose the temperature sensing element of the fire damper to furnace conditions.
Temperature and integrity measurements are carried out in various parts of the test construction during the
test. The leakage of the fire damper system is measured (continuously during the test) by direct flow
measurements whilst maintaining a constant pressure differential across the closed fire damper of 300 Pa.
The leakage of the fire damper in the closed position is also measured at ambient temperature, where a
reduced leakage classification is required to be achieved.
Caution
The attention of all persons concerned with managing and carrying out this fire resistance test is drawn to the
fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful smoke and
gases may be evolved during the test. Mechanical and operational hazards may also arise during the
construction of the test elements or structures, their testing and disposal of test residues.
An assessment of all potential hazards and risks to health shall be made and safety precautions shall be
identified and provided. Written safety instructions shall be issued. Appropriate training shall be given to
relevant personnel. Laboratory personnel shall ensure that they follow written safety instructions at all times.
1 Scope
This Part of EN 1366 specifies a method for determining the fire resistance of fire dampers installed in fire
separating elements designed to withstand heat and the passage of smoke and gases at high temperature.
The Standard is used in conjunction with EN 1363-1.
This standard is not suitable for testing fire dampers in suspended ceilings without modification.

3 Terms and Definitions
For the purposes of this Part of EN 1366, the definitions given in EN 1363-1 and prEN ISO 13943, together
with the following, apply:
3.1
fire damper
a device for use in heating, ventilation and air-conditioning (HVAC) systems at fire boundaries to maintain
compartmentation and protect means of escape in case of fire – it may have reduced smoke leakage
characteristics
3.2
insulated fire damper
a fire damper which satisfies both the integrity and insulation criteria for the anticipated fire resistance period
3.3
uninsulated fire damper
a fire damper which satisfies the integrity criteria for the anticipated fire resistance period, but which does not
provide a long enough insulation period to gain an EI classification
3.4
fire damper actuating mechanism
a mechanism, integral or directly associated with the fire damper which, when initiated causes the damper to
change from the "open" to the "closed" position
3.5
temperature sensing element
a thermally actuated device designed to respond to a rise in temperature of the surrounding air and release
the fire damper blade(s) at a predetermined temperature. It can interface with mechanical, electrical,
electronic, or pneumatically operated actuating mechanisms which are positioned integrally or remotely from
the device
3.6
test specimen
the fire damper, connecting frame and (if applicable) the perimeter penetration sealing system
3.7
connecting duct
the duct section between the fire damper or supporting construction and the measuring station
3.8
test construction
the complete assembly of the test specimen, the connecting
