(Main)Test methods for determining the contribution to the fire resistance of structural members - Part 1: Horizontal protective membranes
Test methods for determining the contribution to the fire resistance of structural members - Part 1: Horizontal protective membranes
This Part of this European Prestandard specifies a test method for determining the ability of a horizontal protective membrane, when used as a fire resistant barrier, to contribute to the fire resistance of horizontal structural building members.
This European Technical Specification contains the fire test which specifies the tests which are carried out whereby the horizontal protective membrane, together with the structural member to be protected, is exposed to a fire test according to the procedures defined herein. The fire exposure, to the temperature/time curve given in EN 1363-1, is applied to the side which would be exposed in practice and from below the membrane itself.
The test method makes provision, through specified optional additional procedures, for the collection of data which can be used as direct input to the calculation of fire resistance according to the processes given within EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2.
A related test method for determining the contribution to the fire protection of vertical structural members by vertical protective membranes is given in Part 2 of this ENV.
This European Technical Specification also contains the assessment which provides information relative to the analysis of the test data and gives guidance for the interpretation of the results of the fire test, in terms of loadbearing capacity criteria of the protected horizontal structural member.
The limits of applicability of the results of the assessment arising from the fire test are defined, together with permitted direct application of the results to different structures, membranes and fittings.
This European Technical Specification applies only where there is a gap and a cavity between the horizontal protective membrane and the structural building member. Otherwise the test methods in ENV 13381-3, ENV 13381-4 or ENV 13381-5, as appropriate, apply.
Tests shall be carried out without additional combustible materials in the cavity.

Foreword
This Technical Specification (CEN/TS 13381-1:2005) has been prepared by Technical Committee
CEN/TC 127 “Fire safety in buildings”, the secretariat of which is held by BSI.
This Technical Specification has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of the
Construction Products Directive. As there was little experience in carrying out these tests in Europe,
CEN/TC127 agreed that more experience should be built up during a pre-standardization period
before agreeing text as European Standards. Consequently all other Parts are being prepared as
European Prestandards.
This Technical Specification is one of a series of standards for evaluating the contribution to the fire
resistance of structural members by applied fire protection materials. Other Parts of this ENV are:
Part 2: Vertical protective membranes,
Part 3: Applied protection to concrete members,
Part 4: Applied protection to steel members,
Part 5: Applied protection to concrete/profiled sheet steel composite members,
Part 6: Applied protection to concrete filled hollow steel columns,
Part 7: Applied protection to timber members.
The fire protection capacity of the horizontal protective membrane can be nullified by the presence of
combustible materials in the cavity above the membrane. The applicability of the results of the
assessment is limited according to the quantity and position of such combustible materials within that
cavity. The amount of combustible material permissible in the cavity should be given in national
regulations.
Annexes A and B are normative.
Caution
The attention of all persons concerned with managing and carrying out this fire resistance test, 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 can be evolved during the test. Mechanical and operational hazards can
also arise during the construction of test elements or structures, their testing and the 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.
The specific health and safety instructions contained within this European Technical Specification
should be followed.
WARNING: When performing this test method, laboratories should expect that there may be
significant quantities of smoke released. This smoke release is expected to be very significant where
the fire test involves timber and timber based components. Laboratories should ensure that
appropriate smoke extraction facilities are provided.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.
1 Scope
This Part of this European Prestandard specifies a test method for determining the ability of a
horizontal protective membrane, when used as a fire resistant barrier, to contribute to the fire
resistance of horizontal structural building members.
This European Technical Specification contains the fire test which specifies the tests which are
carried out whereby the horizontal protective membrane, together with the structural member to be
protected, is exposed to a fire test according to the procedures defined herein. The fire exposure, to
the temperature/time curve given in EN 1363-1, is applied to the side which would be exposed in
practice and from below the membrane itself.
The test method makes provision, through specified optional additional procedures, for the collection
of data which can be used as direct input to the calculation of fire resistance according to the
processes given within EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2.
A related test method for determining the contribution to the fire protection of vertical structural
members by vertical protective membranes is given in Part 2 of this ENV.
This European Technical Specification also contains the assessment which provides information
relative to the analysis of the test data and gives guidance for the interpretation of the results of the
fire test, in terms of loadbearing capacity criteria of the protected horizontal structural member.
The limits of applicability of the results of the assessment arising from the fire test are defined,
together with permitted direct application of the results to different structures, membranes and fittings.
This European Technical Specification applies only where there is a gap and a cavity between the
horizontal protective membrane and the structural building member. Otherwise the test methods in
ENV 13381-3, ENV 13381-4 or ENV 13381-5, as appropriate, apply.
Tests shall be carried out without additional combustible materials in the cavity.
Annex A gives details of assessing the performance of the ceiling when exposed to a semi-natural fire.
