Test methods for determining the contribution to the fire resistance of structural members - Part 3: Applied protection to concrete members
This part of this European Prestandard specifies a test method for determining the contribution of fire protection systems to the fire resistance of structural concrete members, for instance slabs, floors, roofs and walls and which can include integral beams and columns. The concrete can be lightweight, normalweight or heavyweight concrete and of strength classes 20/25 (LC/C/HC) to 50/60 (LC/C/HC). The member can contain steel reinforcing bars.
The test method is applicable to all fire protection materials used for the protection of concrete members and includes sprayed materials, coatings, cladding protection systems and multi-layer or composite fire protection materials, when the gap between the fire protection material and the concrete member is less than 5 mm. Otherwise the test methods in prENV 13381-1 or prENV 13381-2, as appropriate, apply
This European Prestandard contains the fire test which specifies the tests which should be carried out to determine the ability of the fire protection material to remain coherent and fixed to the concrete and to provide data on the temperature distribution throughout the protected concrete member, when exposed to the standard temperature time curve.
In special circumstances, where specified in national building regulations, there can be a need to subject the protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in annex A.
The fire test methodology makes provision for the collection and presentation of data which can be used as direct input to the calculation of fire resistance of concrete members in accordance with the procedures given in ENV 1992-1-2.
This European Prestandard also contains the assessment which prescribes how the analysis of the test data should be made and gives guidance to the procedures by which interpolation should be undertaken.

Foreword
This document ENV 13381-3:2002 has been prepared by Technical Committee CEN/TC127 "Fire safety in buildings",
the secretariat of which is held by BSI.
This document has been prepared under a mandate given to CEN by the European Commission and the European Free
Trade Association.
As there was little experience in carrying out these tests in Europe CEN/TC127 agreed that more experience should be
built up during a prestandardization period before agreeing text as European Standards. Consequently all parts are being
prepared as European Prestandards.
This European Prestandard 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 1: Horizontal protective membranes.
Part 2: Vertical protective membranes.
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.
Annexes A, B and C 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 prestandard should be followed.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries
are bound to announce this European Prestandard: Austria, Belgium, Czech Republic, Denmark, Finland, France,
Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland
and the United Kingdom.
1 Scope
This part of this European Prestandard specifies a test method for determining the contribution of fire protection
systems to the fire resistance of structural concrete members, for instance slabs, floors, roofs and walls and which
can include integral beams and columns. The concrete can be lightweight, normalweight or heavyweight concrete
and of strength classes 20/25 (LC/C/HC) to 50/60 (LC/C/HC). The member can contain steel reinforcing bars.
The test method is applicable to all fire protection materials used for the protection of concrete members and
includes sprayed materials, coatings, cladding protection systems and multi-layer or composite fire protection
materials, when the gap between the fire protection material and the concrete member is less than 5 mm.
Otherwise the test methods in prENV 13381-1 or ENV 13381-2, as appropriate, apply.
This European Prestandard contains the fire test which specifies the tests which should be carried out to
determine the ability of the fire protection material to remain coherent and fixed to the concrete and to provide
data on the temperature distribution throughout the protected concrete member, when exposed to the standard
temperature time curve.
In special circumstances, where specified in national building regulations, there can be a need to subject the
protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed
in annex A.
The fire test methodology makes provision for the collection and presentation of data which can be used as direct
input to the calculation of fire resistance of concrete members in accordance with the procedures given in
ENV 1992-1-2.
This European Prestandard also contains the assessment which prescribes how the analysis of the test data should
be made and gives guidance to the procedures by which interpolation should be undertaken.
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 concrete structures, densities, strengths, thicknesses and
production techniques over the range of thicknesses of the applied fire protection system tested.
