Test methods for determining the contribution to the fire resistance of structural members - Part 8: Applied reactive protection to steel members
This European Standard specifies a test method for determining the contribution made by applied reactive fire protection systems to the fire resistance of structural steel members, which can be used as beams or columns. It considers only sections without openings in the web. It is not directly applicable to structural tension members without further evaluation. Results from analysis of I or Hsections are directly applicable to angles, channels and T-sections for the same section factor, whether used as individual elements or as bracing. This European Standard does not apply to solid bar or rod. It covers fire protection systems that involve only reactive materials and not to passive fire protection materials as defined in this document. The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel sections, characterized by their section factors, a range of design temperatures and a range of valid fire protection classification periods. This European Standard contains the fire test procedures, which specifies the tests which should be carried out to determine the ability of the fire protection system to remain coherent and attached to the steelwork, and to provide data on the thermal characteristics of the fire protection system, when exposed to the standard temperature/time curve specified in EN 1363-1. 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 described 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 steel structural members in accordance with the procedures given in EN 1993-1-2 and EN 1994-1-2. This European Standard also contains the assessment, which prescribes how the analysis of the test data shall be made and gives guidance on the procedures by which interpolation should be undertaken. The assessment procedure is used to establish: a) on the basis of temperature data derived from testing loaded and unloaded sections, a correction factor and any practical constraints on the use of the fire protection system under fire test conditions (the physical performance); b) on the basis of the temperature data derived from testing short steel sections, the thermal properties of the fire protection system (the thermal performance). 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 sections and grades and to the fire protection system. The results of the test and assessment obtained according to this European Standard are directly applicable to steel sections of I and H cross sectional shape and hollow sections.
Prüfverfahren zur Bestimmung des Beitrages zum Feuerwiderstand von tragenden Bauteilen - Teil 8: Reaktive Ummantelung von Stahlbauteilen
Diese Europäische Norm legt ein Prüfverfahren zur Ermittlung des Beitrages reaktiver Brandschutzsysteme zur Feuerwiderstandsfähigkeit von Stahlbauteilen, die als Träger oder Stützen eingesetzt werden können, fest. Berücksichtigt werden lediglich Bauteile ohne Öffnungen im Steg. Auf Zugträger ist eine direkte Anwendung nicht ohne eine weitere Beurteilung möglich. Ergebnisse der Analyse von I- oder H-Profilen sind direkt auf Winkelstücke, U-Profile und T-Profile für denselben Profilfaktor anwendbar, wobei sie als Einzelbauteile oder als Verband verwendet werden können. Diese Europäische Norm gilt nicht für Vollstangen oder Rundstäbe.
Diese Europäische Norm bezieht sich auf Brandschutzsysteme, die lediglich aus reaktiven Materialien bestehen, nicht jedoch auf passive Brandschutzmaterialien.
In die Bewertung einbezogen werden verschiedene Schichtdicken des angewendeten Brandschutzmaterials, verschiedene durch ihren Profilfaktor charakterisierte Stahlbauteile, verschiedene Bemessungstemperaturen sowie eine Bandbreite möglicher Feuerwiderstandsdauern.
Diese Europäische Norm beschreibt die Prüfverfahren für die Brandprüfungen, die zur Bestimmung der Formstabilität des Brandschutzsystems und seines Haftvermögens auf Stahlbauteilen sowie zur Ermittlung der thermischen Eigenschaften des Brandschutzsystems bei Beanspruchung unter den Bedingungen der Einheits-Temperaturzeitkurve nach EN 1363-1 durchgeführt werden.
In bestimmten, in den nationalen Bauvorschriften festgelegten Situationen kann es erforderlich sein, reaktive Brandschutzmaterialien mit einer Schwelbrandkurve zu prüfen. Die entsprechende Prüfung und die beson-deren Umstände für ihre Anwendung sind in Anhang A beschrieben.
Mit dem Brandprüfverfahren können Daten erfasst und dargestellt werden, die direkt in die Berechnung der Feuerwiderstandsfähigkeit von Stahlbauteilen nach den in EN 1993 1 2 und EN 1994 1 2 angegebenen Verfahren einfließen.

Méthodes d'essai pour déterminer la contribution à la résistance au feu des éléments de construction - Partie 8: Protection réactive appliquée aux éléments en acier
La présente Norme européenne spécifie une méthode d’essai permettant de déterminer la contribution
apportée par l’application de systèmes réactifs de protection au feu aux éléments de construction en acier
pouvant être utilisés comme des poutres ou des poteaux. Elle ne prend en compte que les tronçons ne
comportant pas d’ouverture dans l’âme. Elle ne s’applique pas directement aux éléments précontraints sans
évaluation supplémentaire. Les résultats des analyses des sections en I ou H s’appliquent directement aux
cornières, profilés en U et sections en T pour le même facteur de massiveté, qu’ils soient utilisés
individuellement ou en entretoisement. La présente Norme européenne ne s’applique pas aux barres ni aux
tiges pleines.
La présente norme couvre des systèmes de protection contre l’incendie impliquant uniquement des matériaux
réactifs et non passifs, tels qu’ils sont définis dans le présent document.
L’évaluation est conçue pour couvrir une plage d’épaisseurs du matériau de protection au feu appliqué, une
plage de sections d’acier, caractérisées par leurs facteurs de massiveté, une plage de températures de calcul
et une plage de durée de classification des protections au feu en cours de validité.
La présente Norme Européenne comprend les modes opératoires d’essai au feu qui spécifient les essais qu’il
convient de réaliser pour déterminer l’aptitude du système de protection au feu à rester cohérent et fixé sur
l’ossature en acier et pour fournir des données sur les caractéristiques thermiques du système de protection
au feu lorsqu’il est exposé à la courbe normalisée température/temps prescrite dans l’EN 1363-1.
Dans des cas particuliers, tels que spécifiés dans la réglementation nationale de la construction, il peut
s’avérer nécessaire de soumettre le matériau de protection réactif à une courbe de température de feu
couvant, dont l’essai et les cas d’utilisation particuliers sont décrits dans l’Annexe A.
Preskusne metode za ugotavljanje prispevka k požarni odpornosti konstrukcijskih elementov - 8. del: Zaščita jeklenih elementov
Ta evropski standard določa preskusno metodo za ugotavljanje prispevka sistemov za zaščito pred ognjem k požarni odpornosti konstrukcijskih jeklenih elementov, ki se lahko uporabijo kot gredi ali stolpi. Obravnava zgolj odseke brez odprtin v mreži. Brez nadaljnjega ovrednotenja ne velja neposredno za konstrukcijske elemente za napetost. Rezultati analize prerezov v obliki črke I ali H veljajo neposredno za kote, kanale in prereze v obliki črke T pri istem dejavniku prereza, ne glede na to, ali se uporabijo kot posamični elementi ali kot opora. Ta evropski standard ne velja za trdne drogove ali palice. Zajema sisteme za zaščito pred ognjem, ki vključujejo reaktivne materiale in ne materiale za pasivno zaščito pred ognjem, kot oso opredeljeni v tem dokumentu. Ovrednotenje zajema nabor debeline materiala za zaščito pred ognjem, nabor jeklenih prerezov, ki jih določajo dejavniki prereza, nabor načrtovanih temperatur in nabor veljavnih klasifikacijskih obdobjih zaščite pred ognjem. Ta evropski standard vsebuje postopke za preskušanje požarne varnosti, ki določajo preskuse, ki morajo biti izvedeni za določevanje zmožnosti sistema za zaščito pred ognjem, da ostane koherenten in pritrjen na livarno in da zagotavljajo podatke o termalnih značilnostih sistema za zaščito pred ognjem, kadar je le-ta izpostavljen standardni temperaturni/časovni krivulji, določeni v EN 1363-1. V posebnih okoliščinah, kadar so opredeljene v nacionalnih gradbenih predpisih, lahko obstaja potreba, da se reaktivni material za zaščito podvrže krivulji tlenja, preskus tega in posebnih okoliščin za njegovo uporabo, pa so opisani v Dodatku A. Metodologija preskusov požarne varnosti določa zbiranje in predstavitev podatkov, ki se lahko uporabljajo kot neposredni vnos za izračun požarne odpornosti jeklenih konstrukcijskih elementov v skladu s postopki, podanimi v EN 1993-1-2. Ta evropski standard prav tako vsebuje oceno, ki predpisuje, kako naj bo analiza preskusnih podatkov izvedena, ter podaja smernice za postopke, s katerimi se je potrebno lotiti interpolacije. Postopek ocenjevanja se uporablja za ugotavljanje: a) podatkov na osnovi temperature, izvedenih iz preskusnih obremenjenih in neobremenjenih prerezov, korekcijskega dejavnika in praktičnih omejitev uporabe sistema za zaščito pred ognjem (fizična zmogljivost); b) podatkov, na osnovi temperature, izvedenih iz preskušanja kratkih jeklenih prerezov in termalnih lastnosti sistema za zaščito pred ognjem (termalna zmogljivost). Omejitve veljavnosti teh rezultatov ocenjevanja, ki izhajajo iz preskušanja požarne varnosti, so opredeljene, skupaj z dovoljeno neposredno uporabo rezultatov za različne jeklene prereze in vrste jekla ter za sistem za zaščito pred ognjem. Ti rezultati preskušanja in ocenjevanja, pridobljeni v skladu s tem evropskih standardom, so neposredno veljavni za jeklene prereze v obliki črke I in H ter za votle prereze.
