Test methods for determining the contribution to the fire resistance of structural members - Part 6: Applied protection to concrete filled hollow steel columns
This Part of this European Prestandard specifies a test method for determining the contribu-tion of fire protection systems to the fire resistance of structural concrete filled hollow steel columns. The concrete can be lightweight, normal-weight or heavy-weight concrete and of strength classes 20/25 (LC/C/HC) to 50/60 (LC/C/HC).
The method is applicable to all fire protection systems used for the protection of such structural columns and includes sprayed fire protection, coatings, cladding protection systems and multi-layer or composite fire protection materials.
The test method and its assessment procedure is designed to permit direct application of the results to cover a range of thicknesses of the applied fire protection material.
The test method is only applicable to fire protection systems which are fixed directly to the structural column. Fire protection systems where the fire protection material is not attached directly to the composite column, leading to a continuous cavity between the column and the fire protection material of size greater than 5 mm are the subject of prENV 13381-2.
This European Prestandard contains the fire test which specifies the tests which should be carried out to determine the ability of the fire protection system to remain coherent and fixed to the composite column and to provide data on the temperatures of the outer steel surface of the composite column, when exposed to the standard time/temperature curve according to the procedures defined herein.
In special circumstances, where specified in national building regulations, there can be a need to subject reactive protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in annex A.
This exposure, applicable to reactive fire protection materials, is used only in special circumstances, where specified in the national building regulations of a member state of the European Union, and is not intended to be ma
Prüfverfahren zur Bestimmung des Beitrages zum Feuerwiderstand von tragenden Bauteilen - Teil 6: Brandschutzmaßnahmen für betonverfüllte Stahlverbund-Hohlstützen
Dieser Teil dieser Europäischen Vornorm legt ein Prüfverfahren fest zur Bestimmung des Beitrags der Brandschutzsysteme zur Feuerwiderstandsfähigkeit von tragenden betonverfüllten Stahlverbund-Hohlstützen. Der Beton kann Leichtbeton, Normalbeton oder Schwerbeton der Festigkeitsklassen 20/25 (LC/C/HC) bis 50/60 (LC/C/HC) sein.
Das Prüfverfahren gilt für alle Brandschutzsysteme, die für den Schutz der tragenden Stützen verwendet werden und beinhaltet aufgesprühte Brandschutzmaterialien, Bekleidungen, Beschichtungsschutzsysteme und Mehr-schicht- oder Verbundsysteme.
Das Prüfverfahren und sein Beurteilungsverfahren sind so ausgelegt, dass eine direkte Anwendung der Ergebnisse möglich ist, um einen Bereich von Dicken des aufgebrachten Brandschutzmaterials abzudecken.
Das Prüfverfahren gilt nur für Brandschutzsysteme, die direkt auf der tragenden Stütze befestigt sind. Brandschutzsysteme, bei denen das Brandschutzmaterial nicht direkt auf der Verbundstütze befestigt ist und bei denen dadurch ein durchgehender Hohlraum zwischen der Stütze und dem Brandschutzmaterial von mehr als 5 mm entsteht, werden in ENV 13381-2 behandelt.
Diese Europäische Vornorm beinhaltet die Brandprüfung, die durchgeführt werden sollte, um die Fähigkeit des Brandschutzsystems, mit der Verbundstütze fest verbunden zu bleiben, zu bestimmen und um Daten über die Temperaturen der äußeren Stahloberfläche der Verbundstütze zu liefern, wenn diese der Einheits-Temperaturzeitkurve nach den hier definierten Verfahren ausgesetzt wird.
Unter besonderen Umständen, die in nationalen Regelungen festgelegt sind, kann es erforderlich sein, das reaktive Brandschutzmaterial einer Schwelbrandkurve zu unterziehen. Die Prüfung und die besonderen Umstände für deren Anwendung sind in Anhang A angegeben.
Méthodes ds'essai pour déterminer la contribution à la résistance au feu des éléments de construction - Partie 6: Protection appliquée aux poteaux métalliques creux remplis de béton
Cette partie de l'ENV 13381 spécifie une méthode d'essai permettant de déterminer la contribution apportée par les systèmes de protection contre le feu à la résistance au feu des poteaux métalliques creux remplis de béton. Le béton peut être de type léger, normal ou compact et appartenir aux classes de résistance aux contraintes 20/25 (LC/C/HC) à 50/60 (LC/C/HC). La méthode d'essai est applicable à tous les systèmes de protection contre le feu utilisés pour protéger ce type de poteau et englobe les matériaux de protection contre le feu appliqués par pulvérisation, les revêtements, les systèmes de protection en plaque et les matériaux de protection contre le feu multi-couches ou composites. La méthode d'essai et sa procédure d'évaluation sont conçues pour permettre l'application directe des résultats à une gamme d'épaisseurs du matériau de protection contre le feu. La méthode d'essai est seulement applicable aux systèmes de protection contre le feu qui sont fixés directement sur le poteau. Les systèmes dans lesquels le matériau de protection contre le feu n'est pas fixé directement sur le poteau mixte, entraînant la présence d'une cavité continue, mesurant plus de 5 mm, entre le poteau et le système de protection contre le feu constituent l'objet de l'ENV 13381-2. La présente prénorme européenne contient l'essai au feu, qui spécifie les essais qui doivent être effectués pour déterminer l'aptitude du système de protection contre le feu à rester cohérent et fixé sur le poteau mixte, et pour obtenir des données concernant les températures de la surface extérieure en acier du poteau mixte, lorsque ce poteau est exposée au feu suivant la courbe de température/temps normalisée, conformément aux procédures définies dans le présent document. Dans des circonstances particulières, lorsque des règlements nationaux le prescrit, il peut être nécessaire

Foreword
This document ENV 13381-6:2002 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 the mandate given to CEN/TC127 by the Commission of the European Committees
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 Prestandardisation 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 the ENV are:
Part 1: Horizontal protective membranes.
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 7: Applied protection to timber members.
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 fact that fire testing
may 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 test 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.
1Scope
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 filled hollow steel columns. The concrete can be lightweight,
normal-weight or heavy-weight concrete and of strength classes 20/25 (LC/C/HC) to 50/60 (LC/C/HC).
The method is applicable to all fire protection systems used for the protection of such structural columns and
includes sprayed fire protection, coatings, cladding protection systems and multi-layer or composite fire protection
materials.
The test method and its assessment procedure is designed to permit direct application of the results to cover a range
of thicknesses of the applied fire protection material.
The test method is only applicable to fire protection systems which are fixed directly to the structural column. Fire
protection systems where the fire protection material is not attached directly to the composite column, leading to a
continuous cavity between the column and the fire protection material of size greater than 5 mm are the subject of
ENV 13381-2.
This European Prestandard contains the fire test which specifies the tests which should be carried out to determine
the ability of the fire protection system to remain coherent and fixed to the composite column and to provide data
on the temperatures of the outer steel surface of the composite column, when exposed to the standard
time/temperature curve according to the procedures defined herein.
In special circumstances, where specified in national building regulations, there can be a need to subject reactive
protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed
in annex A.
This exposure, applicable to reactive fire protection materials, is used only in special circumstances, where specified
in the national building regulations of a member state of the European Union, and is not intended to be mandatory
for all fire protection materials applied to concrete filled hollow steel columns.
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/steel composite members in accordance with the procedures
given in ENV 1994-1-2.
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 steel/concrete composite columns, steel types and thicknesses,
concrete densities, strengths, thicknesses and production techniques over the range of thicknesses of the applied fire
protection system tested.
