Foreword
This document (prEN 1366-12:2010) 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 has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
Introduction
The purpose of the test is to evaluate the ability of a non-mechanical (no moving parts) 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.
It identifies the requirements needed to adapt the test method described in EN 1366-2 (which was intended for
mechanical dampers) to suit non-mechanical fire dampers.
Non-mechanical fire dampers are unable to achieve an “S” classification, which requires a known ambient
leakage, as they are unable to be closed except under fire conditions.
The non-mechanical 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 its cold standard state to expose it 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.
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 should be made and safety precautions
should be identified and provided. Written safety instructions should be issued. Appropriate training
should be given to relevant personnel. Laboratory personnel should ensure that they follow written
safety instructions at all times.

1 Scope
This European Standard specifies a method for determining the fire resistance of non-mechanical 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 and EN 1366-2.
This standard is not suitable for testing non-mechanical fire dampers in suspended ceilings without
modification.

In addition to the test equipment specified in EN 1363-1, and if applicable, EN 1363-2, the following is
required: Examples of test configurations are shown in figures 1 and 2.
4.2 Connecting duct
The connecting duct shall be of all welded construction fabricated from (1,5 + 0,1) mm thick steel with a width

tight observation window.
