Fire resistance tests - Part 1: General requirements

This document establishes the general principles for determining the fire resistance of various elements of construction when subjected to standard fire exposure conditions. Alternative and additional procedures to meet special requirements are given in EN 1363-2.
The principle that has been embodied within all European Standards relating to fire resistance testing is that where aspects and procedures of testing are common to all specific test methods e.g. the temperature/time curve, then they are specified in this test method. Where a general principle is common to many specific test methods but the details vary according to the element being tested (e.g. the measurement of unexposed face temperature), then the principle is given in this document, but the details are given in the specific test method. Where certain aspects of testing are unique to a particular specific test method (e.g. the air leakage test for fire dampers), then no details are included in this document.
The test results obtained might be directly applicable to other similar elements, or variations of the element tested. The extent to which this application is permitted depends upon the field of direct application of the test result. This is restricted by the provision of rules which limit the variation from the tested specimen without further evaluation. The rules for determining the permitted variations are given in each specific test method.
Variations outside those permitted by direct application are covered under extended application of test results. This results from an in-depth review of the design and performance of a particular product in test(s) by a recognised authority. Further consideration on direct and extended application is given in Annex A.
The duration for which the tested element, as modified by its direct or extended field of application, satisfies specific criteria will permit subsequent classification.
All values given in this document are nominal unless otherwise specified.

Feuerwiderstandsprüfungen - Teil 1: Allgemeine Anforderungen

Dieses Dokument stellt allgemeine Grundsätze für die Bestimmung der Feuerwiderstandsdauer von verschiedenartigen Bauteilen auf, die unter genormten Bedingungen dem Feuer ausgesetzt werden. Alternative und ergänzende Verfahren zur Erfüllung besonderer Anforderungen sind in EN 1363-2 angegeben.
Alle Europäischen Normen zur Feuerwiderstandsprüfung folgen dem Prinzip, dass Aspekte und Durch-führungen, die für alle spezifischen Prüfverfahren gemeinsam gelten, z. B. die Temperaturzeitkurve, in diesem Prüfverfahren festgelegt sind. Gilt für viele spezifische Prüfverfahren ein gemeinsames Prinzip während jedoch die Details in Abhängigkeit vom zu prüfenden Bauteil variieren, (z. B. die Messung der Temperatur auf der unbeflammten Seite), dann ist dieses Prinzip in der vorliegenden Norm enthalten, die Details sind jedoch im spezifischen Prüfverfahren angegeben. Sind bei einem bestimmten spezifischen Prüfverfahren bestimmte Aspekte der Prüfung für dieses Prüfverfahren einmalig (z. B. die Prüfung der Leckrate bei Brandschutzklappen), dann sind im vorliegenden Dokument keine Details enthalten.
Die erzielten Prüfergebnisse dürfen direkt auf andere ähnliche Bauteile oder Varianten des geprüften Bauteils angewandt werden. Der Umfang, in dem die Übertragung dieser Ergebnisse zulässig ist, hängt vom direkten Anwendungsbereich des Prüfergebnisses ab. Diese Vorgehensweise wird durch die Bereitstellung von Regeln, die die Abweichungen vom geprüften Probekörper ohne weitere Beurteilung begrenzen, eingeschränkt. Die Regeln zur Bestimmung zulässiger Abweichungen sind zu jedem spezifischen Prüf-verfahren angegeben.
Abweichungen, die nicht innerhalb des direkten Anwendungsbereiches zugelassen sind, werden im "Erweiterten Anwendungsbereich von Prüfergebnissen" behandelt. Dies ergibt sich aus einer eingehenden Überprüfung der Ausführung und des Leistungsverhaltens eines besonderen Produkts bei Prüfung(en) durch eine anerkannte Stelle. Weitere Betrachtungen zum direkten und erweiterten Anwendungsbereich sind in Anhang A angegeben.
Die Zeitdauer, innerhalb der das geprüfte Bauteil die entsprechenden Kriterien erfüllt, erlaubt die anschließende Klassifizierung dieses Bauteils, einschließlich der durch den direkten oder erweiterten Anwendungsbereich möglichen Modifizierungen.
Falls nichts anderes festgelegt ist, sind sämtliche in diesem Dokument angegebenen Werte Nennwerte.

Essais de résistance au feu - Partie 1 : Exigences générales

La présente Norme européenne établit les principes généraux pour la détermination de la résistance au feu de divers éléments de construction lorsqu'ils sont soumis à des conditions normalisées d'exposition au feu. Des variantes et des modes opératoires supplémentaires pour répondre à des prescriptions spéciales sont donnés dans la norme EN 1363-2.
Le principe qui a été retenu dans toutes les Normes européennes se rapportant aux essais de résistance au feu est que, dans tous les cas où les caractéristiques et les modes opératoires des essais sont communs à toutes les méthodes d'essais spécifiques (la courbe de température en fonction du temps par exemple), ils sont alors prescrits dans la présente méthode d'essai. Dans le cas où un principe général est commun à de nombreuses méthodes d'essai spécifiques mais varie dans le détail en fonction de l'élément soumis aux essais (par exemple le mesurage de la température sur la face non exposée), le principe est alors donné dans le présent document mais les détails sont indiqués dans la méthode d'essai spécifique. Dans le cas où certains aspects des essais intéressent exclusivement une méthode d'essai spécifique particulière (essai de fuite d'air pour les clapets coupe-feu par exemple), aucun détail ne figure alors dans le présent document.
Il est permis d'appliquer directement les résultats obtenus lors des essais à d'autres éléments similaires ou à des variantes de l'élément soumis aux essais. La mesure dans laquelle cela est admis dépend du domaine d'application directe des résultats de l'essai. Ce point est limité à la définition de règles fixant la variation par rapport à l'élément d'essai soumise aux essais sans autre évaluation. Les règles à suivre pour déterminer les variations admises sont données dans chaque méthode d'essai spécifique.
Les variations en dehors de celles admises par l'application directe sont couvertes dans le cadre d'une application étendue des résultats d'essai. Celle-ci résulte d'un examen approfondi, par une autorité reconnue, de la conception d'un produit particulier et de son comportement au cours d'un ou plusieurs essais. Dans l'Annexe A sont indiquées d'autres considérations sur les applications directes et étendues.
La durée pendant laquelle l'élément soumis aux essais, modifié par son domaine d'application directe ou étendue, satisfait les critères spécifiques, permettra sa classification.
Sauf indication contraire, toutes les valeurs données dans la présente norme sont des valeurs nominales.

Introduction

The objective of determining fire resistance is to assess the behaviour of a specimen of an element of

building construction when subjected to defined heating and pressure conditions. The method provides

a means of quantifying the ability of an element to withstand exposure to high temperatures. It does so

by setting criteria against which the loadbearing capacity, the fire containment (integrity) and the

thermal transmittance (insulation) functions amongst other characteristics can be evaluated.

A representative sample of the element is exposed to a specified regime of heating and the performance

of the test specimen is monitored on the basis of criteria described in the standard. Fire resistance of the

test element is expressed as the time for which the appropriate criteria have been satisfied. The times so

obtained are a measure of the adequacy of the construction in a fire; but they have no direct relationship

with the duration time of a real fire.
Caution

The attention of all persons concerned with managing and carrying out fire resistance testing is drawn to

the fact that fire testing might 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 needs to be made and safety precautions need

to be identified and provided. Written safety instructions will be issued. Appropriate training will be

given to relevant personnel. Laboratory personnel will ensure that they follow written safety instructions

at all times.
Uncertainty of measurement of fire resistance

There are many factors which can affect the result of a fire resistance test. Those concerned with the

variability of the specimen including its materials, manufacture and installation are not related to the

uncertainty of measurement. Of the remainder, some, such as the different thermal dose provided by

different furnaces, are much more significant than others such as the accuracy of calibration of the data

logging system.

Because of the very labour intensive nature of the test, many of the factors that have a bearing on the

result are operator-dependent. The training, experience and attitude of the operator is thus crucial to

eliminate such variables which can significantly affect the degree of uncertainty of measurement.

Unfortunately, it is not possible to numerically quantify these factors and therefore any attempt to

determine uncertainty of measurement that does not take into account operator-dependent variables is

of limited value.

1 Scope

This document establishes the general principles for determining the fire resistance of various elements

of construction when subjected to standard fire exposure conditions. Alternative and additional

procedures to meet special requirements are given in EN 1363-2.

The principle that has been embodied within all European standards relating to fire resistance testing is

that where aspects and procedures of testing are common to all specific test methods e.g. the

temperature/time curve, then they are specified in this test method. Where a general principle is common

to many specific test methods but the details vary according to the element being tested (e.g. the

measurement of unexposed face temperature), then the principle is given in this document, but the

details are given in the specific test method. Where certain aspects of testing are unique to a particular

specific test method (e.g. the air leakage test for fire dampers), then no details are included in this

document.

The test results obtained might be directly applicable to other similar elements, or variations of the

element tested. The extent to which this application is permitted depends upon the field of direct

application of the test result. This is restricted by the provision of rules which limit the variation from the

tested specimen without further evaluation. The rules for determining the permitted variations are given

in each specific test method.

Variations outside those permitted by direct application are covered under extended application of test

results. This results from an in-depth review of the design and performance of a particular product in

test(s) by a recognized authority. Further consideration on direct and extended application is given in

Annex A.

The duration for which the tested element, as modified by its direct or extended field of application,

satisfies specific criteria will permit subsequent classification.
All values given in this document are nominal unless otherwise specified.
