Safety in Buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersedes EN 1366-3:2009.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association.
Annexes A to G are normative. Annex H is informative.

Introduction
This part of the EN 1366 series has been prepared to provide a method of test for assessing the
contribution of a penetration seal to the fire resistance of separating elements when they have
been penetrated by a service or services.
Caution
The attention of all persons concerned with managing and carrying out fire resistance testing is
drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic and/or
harmful smoke and gases will be emitted during the test. Mechanical and operational hazards
might 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 part of the EN 1366 series specifies a method of test and criteria for the evaluation (including
field of direct application rules) of the ability of a penetration seal to maintain the fire resistance of
a separating element at the position at which it has been penetrated by a service or services.
Penetration seals used to seal gaps around chimneys, air ventilation systems, fire rated ventilation
ducts, fire rated service ducts, shafts and smoke extraction ducts as well as combined penetration
seals are excluded from this part of the EN 1366 series. Supporting constructions are used in this
part of the EN 1366 series to represent separating elements such as walls or floors. These simulate
the interaction between the test specimen and the separating element into which the sealing
system is to be installed in practice.
This part of the EN 1366 series is intended to be used in conjunction with EN 1363-1.
The purpose of a test described in this part of the EN 1366 series is to assess the integrity and
insulation performance of the penetration seal, of the penetrating service or services and of the
separating element in the surrounding area of the penetration seal.
No information can be implied by the test concerning the influence of the inclusion of such
penetrations and penetration seals on the loadbearing capacity of the separating element.
It is assumed that in each case the lintel above a penetration seal in the wall is designed in hot and
cold state in a way that it does not apply any additional vertical load on the penetration seal.
It is not the intention of this test to provide quantitative information on the rate of leakage of
smoke and/or hot gases or on the transmission or generation of fumes. Such phenomena are only
to be noted in the test report in describing the general behaviour of test specimens during the test.
Tests in accordance with this part of the EN 1366 series are not intended to supply any information
on the ability of the penetration seal to withstand stress caused by movements or displacements of
the penetrating services.
The risk of spread of fire downwards caused by burning material, which drips through a pipe
downwards to floors below, cannot be assessed with this test.
Tests in accordance with this part of the EN 1366 series do not address any risks associated with
leakage of dangerous liquids or gases caused by failure of the pipe(s) in case of fire.
Tests in accordance with this part of the EN 1366 series of pipe penetration seals for pipes of
pneumatic dispatch systems, pressurized air systems etc. simulate a situation where the systems
are shut off in case of fire.
Explanatory notes to this test method are given in Annex H.
All values given without tolerances in this Standard are nominal ones unless otherwise specified.
