Fire resistance tests - Part 1: General Requirements

This European Standard 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 Standard are nominal unless otherwise specified.

Feuerwiderstandsprüfungen - Teil 1: Allgemeine Anforderungen

Diese Europäische Norm 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 Durchführungen, 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 Prüfverfahren 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 dieser Norm angegebenen Werte Nennwerte.

Essais de résistance au feu - Partie 1: Exigences générales

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 est indiquée dans le
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 du 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 d'établir sa classification appropriée.
Sauf indication contraire, toutes les valeurs données dans la présente norme sont des valeurs nominales.

Preskusi požarne odpornosti - 1. del: Splošne zahteve

Ta evropski standard vzpostavlja osnovna načela za določanje požarne odpornosti različnih konstrukcijskih elementov pri standardnih pogojih izpostavljenosti ognju. Drugi in dodatni postopki za doseganje posebnih zahtev so navedeni v standardu EN 1363-2. Načelo, vključeno v vse evropske standarde, ki se nanašajo na preskušanje s področja požarne odpornosti, določa, da so vidiki in postopki preskušanja, če so skupni vsem specifičnim preskusnim metodam, npr. krivulja temperatura-čas, opredeljeni v okviru te preskusne metode. Če je splošno načelo enako za več specifičnih preskusnih metod, vendar se slednje razlikujejo v podrobnostih glede na element, ki se preskuša (npr. merjenje temperaturno neizpostavljenih delov), je to načelo navedeno v tem dokumentu, podrobnosti pa v okviru specifične preskusne metode. Če so nekateri vidiki preskušanja edinstveni za posamezno specifično preskusno metodo (npr. preskus uhajanja zraka za dušilnike ognja), v tem dokumentu ni podrobnosti. Doseženi rezultati preskusa so lahko neposredno uporabni za druge podobne elemente ali različice preskušenega elementa. Obseg dovoljene uporabe je odvisen od področja neposredne uporabe rezultata preskusa. To določajo pravila, ki omejujejo odstopanja od vzorca preskusa brez nadaljnjega ocenjevanja. Pravila za določanje dovoljenih odstopanj so navedena v posamezni specifični preskusni metodi. Različice, ki v okviru neposredne uporabe niso dovoljene, so vključene v razširjeno uporabo rezultatov preskusa. To je posledica poglobljenega pregleda oblike in učinkovitosti delovanja posameznih izdelkov v okviru preskusov, ki jih opravi pristojna služba. Nadaljnja obravnava neposredne in razširjene uporabe je vključena v Prilogo A. Čas, v katerem preskušani element, spremenjen z neposredno ali razširjeno uporabo, zadovolji posebna merila, bo omogočil nadaljnje razvrščanje. Vse vrednosti, navedene v tem standardu, so nominalne, razen če ni določeno drugače.

SIST EN 1363-1:2012

d) heating of beams on three or four sides, as appropriate. Other special furnaces may be required for specific elements. The furnace linings shall consist of materials with densities less than 1 000 kg/m3. Such lining materials shall have a minimum thickness of 50 mm and shall constitute at least 70 % of the internally exposed surface of the furnace. The furnace shall be capable of providing the standard fire exposure conditions with respect to thermal exposure and pressure.
Furnaces may be designed so that assemblies of more than one element can be tested simultaneously, provided that all the requirements for each individual element can be complied with. 4.3 Loading equipment The loading equipment shall be capable of subjecting test specimens to the level of loading determined in accordance with 5.4. The load may be applied hydraulically, mechanically or by the use of weights. The loading equipment shall be able to simulate conditions of uniform loading, point loading, concentric loading, axial loading or eccentric loading as appropriate for the test construction. The loading equipment shall be capable of maintaining the test load at a constant value (± 5 % of the required value) without changing its distribution and following the maximum deflection and the rate of deflection of the test specimen until failure of loadbearing capacity occurs as defined in 11.3 or for the duration of the test, whichever occurs sooner. The loading equipment shall not significantly influence the heat transfer through the specimen nor impede the use of the thermocouple insulating pads. It shall not interfere with the measurement of surface temperature and/or deflection and shall permit general observation of the unexposed face. The total area of the contact points between the loading equipment and the test specimen surface shall not exceed 10 % of the total area of the surface of a horizontal test specimen.
4.4 Test frames Special test frames or other means shall be employed to reproduce the boundary and support conditions appropriate for the test constructions as required by 5.5. Different types of test constructions will require test frames of differing stiffness. The performance of the test frames shall be evaluated by applying an expansion force within the frame at mid-width between two opposite members and measuring the increase in the internal dimension. The increase shall not exceed 5 mm with an applied force of 25 kN. This evaluation shall be conducted in both directions of the frame. Where test frames are to meet different requirements, these other requirements are given in the specific test method. SIST EN 1363-1:2012

The measuring and recording equipment shall be capable of operating within the limits specified in 4.6. In the case of non-planar surface of the test specimen, the disc and/or pad shall be deformed to follow the main surface profile. If there is difficulty in fixing the standard pad, the size of the pad may be reduced on two parallel sides subject to covering the disc. 4.5.1.3 Roving thermocouples One or more roving thermocouples of the design shown in Figure 3 shall be available to measure the unexposed surface temperature during a test at positions where higher temperatures are suspected. The measuring junction of the thermocouple shall consist of type K thermocouple wires as defined in EN 60584-1, 1,0 mm in diameter soldered to a 12 mm diameter, 0,5 mm thick copper disc. The thermocouple assembly SIST EN 1363-1:2012

4.5.2 Pressure The pressure in the furnace shall be measured by means of one of the designs of sensors described in Figure 4. The measuring and recording equipment shall be capable of operating within the limits specified in 4.6. Data measured at each measuring interval shall be used in the analysis of the test specimen's performance. If the data is presented as fixed or floating average values, the methodology for processing the data presented shall be clearly explained in the test report. 4.5.3 Load When using weights, no further measurement of load in a test is needed. The loads applied by hydraulic loading systems shall be measured by means of a load cell or other relevant equipment having the same accuracy or by monitoring the hydraulic pressure at an appropriate point. The measuring and recording equipment shall be capable of operating within the limits specified in 4.6. 4.5.4 Deflection Deflection measurements can be made by using equipment employing mechanical, optical or electrical techniques. Where such equipment is used in relation to performance criteria, e.g. for measurements of deflection or contraction, it shall be capable of operating at a frequency of at least one reading per minute. All necessary precautions shall be taken to prevent any drift in the sensor readings due to heating. Details of precision of measuring equipment are given in 4.6. 4.5.5 Integrity 4.5.5.1 Cotton pad Unless specified otherwise in the standards for specific elements, the cotton pad employed in the measurement of integrity shall consist of 100 % new, untreated, undyed and soft cotton fibres which shall weigh between 3 g – 4 g per 100 x 100 x 20 mm. It shall be conditioned prior to use by drying in an oven at (100 ± 5) °C for at least 30 min. After drying it may be stored in a desiccator or in an airtight container for up to one week before oven drying again as described above. For use it shall be mounted in a wire frame with sizes of either (100 ± 5) x (100 ± 5) x (20 ± 1) mm or (30 ± 2) x (30 ± 2) x (20 ± 1) mm, as shown in Figure 5, provided with a handle of suitable length. The cotton pad with nominal sizes 30 x 30 x 20 mm shall only be used when required by the specific test method. SIST EN 1363-1:2012
