Extended application on the fire performance of construction products and building elements: Principle of EXAP standards and EXAP reports
This document gives the procedures for preparing standards and reports following the extended application (EXAP) process using the results of reaction to fire tests, fire resistance tests (including other performance characteristics e.g. smoke leakage/control and/or durability of self-closing), and external fire exposure to roof tests undertaken for fire classification of products and product families in accordance with the various parts of EN 13501. EXAP rules limit the number of tests required by implementing methods to determine the fire classification of a range of products (e.g. range of product, larger dimensions etc.) and EXAP rules form a standardized technical agreement on the parameter changes.
The fundamental concept of EXAP is the development of safe methods that provide extensions to the scope of the tested product while maintaining the required classification for the product. Test reports constitute the basis of an EXAP report.
This document makes reference to ‘extended application standards’ throughout; wherever this term is used it refers to either a standard prepared by CEN/TC 127 ‘Fire safety in buildings’ or the relevant product standard which includes information on extended application.
The European system currently permits extended application rules to be included in technical specifications. CEN Technical Committees and EOTA Working groups producing these rules are asked to seek the guidance of CEN/TC 127 to ensure that their rules comply with standards prepared by CEN/TC 127. In cases where extended application rules in harmonized EN product standards and ETAs do not comply with standards prepared by CEN/TC 127 the CEN BT are informed.
This document does not cover the incorporation of the product into the construction works that is justified by national rules.
Expert judgements (i.e. an opinion that is not considered/covered by an EXAP standard and only based on the experience of one individual) do not form part of this process.
Erweiterte Anwendung auf das Brandverhalten von Bauprodukten und Bauteilen: Prinzip der EXAP-Normen und EXAP-Berichte
Dieses Dokument legt die Verfahren für die Erarbeitung von Normen und Berichten nach der Ermittlung der erweiterten Anwendung (EXAP) der Ergebnisse von Prüfungen zum Brandverhalten von Bauprodukten, von Feuerwiderstandsprüfungen (einschließlich anderer Leistungseigenschaften wie beispielsweise Rauchdichtheit/Rauchschutz und/oder Beständigkeit der Selbstschließung) oder von Prüfungen zur Beanspruchung von Bedachungen durch Feuer von außen fest, die für die Klassifizierung von Produkten und Produktfamilien nach den verschiedenen Teilen der Normenreihe EN 13501 durchgeführt wurden. Durch die EXAP-Regelungen wird die Anzahl an erforderlichen Prüfungen begrenzt, indem Methoden zur Bestimmung der Klassifizierung von Bränden eines Produktbereichs eingeführt werden (z. B. Produktbereich, größere Abmessungen usw.), und EXAP-Regeln bilden eine genormte technische Vereinbarung über die Parameteränderungen.
Das grundsätzliche Konzept von EXAP besteht in der Entwicklung sicherer Methoden, die Erweiterungen für den Anwendungsbereich des geprüften Produkts bieten und die erforderliche Klassifizierung des Produkts beibehalten. Prüfberichte bilden die Grundlage eines EXAP-Berichts.
Dieses Dokument verweist im weiteren Verlauf auf „erweiterte Anwendungsnormen“; wo auch immer dieser Begriff angewendet wird, bezieht er sich auf eine andere durch CEN/TC 127 „Baulicher Brandschutz“ erarbeitete Norm oder die betreffende Produktnorm, die Angaben zum erweiterten Anwendungsbereich einschließt.
Das europäische System lässt gegenwärtig die Aufnahme von Regeln zum erweiterten Anwendungsbereich in Technischen Spezifikationen zu. Die Technischen Komitees von CEN und die Arbeitsgruppen von EOTA, die diese Regeln erarbeiten, sind aufgefordert, die Zuarbeit von CEN/TC 127 in Anspruch zu nehmen, um sicherzustellen, dass ihre Regeln den durch CEN/TC 127 erstellten Normen entsprechen. In Fällen, in denen die Regeln zum erweiterten Anwendungsbereich in harmonisierten europäischen Produktnormen (ENs) und in Europäisch-Technischen Bewertungen (ETAs) nicht den von CEN/TC 127 erarbeiteten Normen entsprechen, wird das CEN/BT informiert.
Dieses Dokument umfasst nicht die Einarbeitung des Produkts in Bauwerke, die durch nationale Regeln begründet sind.
Expertenbeurteilungen (d. h. eine Meinung, die nicht von einer EXAP-Norm berücksichtigt/abgedeckt ist und nur auf der Erfahrung einer Person basiert) bilden keinen Teil dieses Prozesses.
Application étendue des performances au feu des produits et éléments de construction : principe relatif aux normes EXAP et aux rapports EXAP
Le présent document indique les modes opératoires à suivre pour l’élaboration des normes et des rapports à la suite de l’application étendue (extended application, EXAP). Ces normes et rapports s’appuient sur les résultats des essais de réaction au feu, de résistance au feu (y compris d’autres caractéristiques de performance, comme le dégagement/l’étanchéité de la fumée et/ou la durabilité de la fermeture automatique) et d’exposition des toitures à un feu extérieur, entrepris pour le classement au feu des produits et des familles de produits, conformément aux diverses parties de l’EN 13501. Les règles relatives aux applications étendues (EXAP) limitent le nombre d’essais requis grâce à la mise en oeuvre de méthodes destinées à déterminer le classement au feu d’une gamme de produits (par exemple, une gamme de produits, des dimensions plus importantes, etc.). Ces règles constituent un accord technique normalisé pour ce qui concerne les modifications de paramètres.
Le concept fondamental d'une EXAP est l’élaboration de méthodes sûres qui fournissent des extensions au domaine d’application du produit soumis à essai tout en maintenant le classement requis pour le produit. Les rapports d’essai constituent la base d’un rapport EXAP.
Le présent document fait référence aux « normes d’application étendue », chaque occurrence de ces termes renvoyant soit à une norme élaborée par le CEN/TC 127 « Sécurité incendie dans le bâtiment » soit à la norme de produit appropriée, laquelle inclut des informations concernant l’application étendue.
Le système européen permet actuellement l’intégration des règles d’application étendue dans les Spécifications techniques. Les comités techniques du CEN et les groupes de travail de l’EOTA produisant ces règles doivent s’appuyer sur les recommandations du CEN/TC 127 afin de s’assurer que lesdites règles sont conformes aux normes élaborées par ce même comité. Lorsque les règles d’application étendue présentes dans les normes de produit harmonisées et les Agréments techniques européens ne sont pas conformes aux normes élaborées par le CEN/TC 127, le BT du CEN en est informé.
Le présent document ne couvre pas l’intégration du produit dans les ouvrages de construction justifiée par les règlements nationaux.
Les avis d’expert (c’est-à-dire les avis qui ne sont pas pris en compte/couverts par une norme EXAP, et qui ne se fondent que sur l’expérience d’un seul individu) ne font pas partie de ce processus.
Poročila za razširjeno uporabo, ki se nanašajo na ognjevarne lastnosti gradbenih proizvodov in elementov stavb: načelo v zvezi s standardi EXAP in poročili EXAP
Ta evropski standard določa postopke za pripravo poročil o postopku razširjene uporabe z rezultati preskusov odziva na ogenj, preskusov požarne odpornosti in preskusov pri izpostavljenosti streh požaru z zunanje strani, ki so izvedeni za požarno klasifikacijo proizvodov in skupin proizvodov v skladu z različnimi deli standarda EN 13501.
Ta standard se vseskozi navezuje na »standarde razširjene uporabe«; ta izraz se nanaša na standard, ki ga je pripravil odbor CEN/TC 127 »Požarna varnost v objektih« ali ustrezen standard za izdelek, ki vključuje informacije o razširjeni uporabi. V nekaterih primerih, če standard še ni objavljen, lahko ustrezni organi izdajo priporočila za uporabo priglašenih organov v postopkih izdajanja potrdil za oznako CE v skladu z direktivo o gradbenih proizvodih (CPD), http://ec.europa.eu/enterprise/newapproach/nando/.
Evropski sistem trenutno dovoljuje vključitev pravil o razširjeni uporabi v tehnične specifikacije. Od tehničnih odborov CEN in delovnih skupin EOTA, ki pripravljajo ta pravila, se zahteva, da poiščejo usmeritve odbora CEN/TC 127, da se zagotovi skladnost teh pravil s standardi, ki jih pripravi odbor CEN/TC 127. V primerih, ko pravila o razširjeni uporabi v harmoniziranih standardih EN o izdelku in soglasjih ETA niso skladna s standardi, ki jih je pripravil odbor CEN/TC 127, je treba obvestiti tehnični odbor CEN BT.

Introduction
A construction product and/or a building element may be placed on the market with different
thicknesses, densities, fixing conditions, substrates, etc. It is not practicable to test all combinations of
different product parameters for the reaction to fire performance or fire resistance or external fire
exposure performance, although these parameters may substantially influence the test result.
A building element is understood to be a defined construction component, e.g. wall, partition, floor, roof,
beam or column.
The process of extended application uses rules which are essentially based on a worst-case scenario and
interpolation techniques. There are a number of practical limitations on the size and design of elements
that can be tested by the standard methods of test for fire resistance. When these elements are larger, or
are of a modified design, there is a necessity to be able to confirm their performance, i.e. whether the
classification(s) given in the classification report in relation to the relevant criteria are maintained,
without the ability of being able to test them.
1 Scope
This document gives the procedures for preparing standards and reports following the extended
application (EXAP) process using the results of reaction to fire tests, fire resistance tests (including other
performance characteristics e.g. smoke leakage/control and/or durability of self-closing), and external
fire exposure to roof tests undertaken for fire classification of products and product families in
accordance with the various parts of EN 13501. EXAP rules limit the number of tests required by
implementing methods to determine the fire classification of a range of products (e.g. range of product,
larger dimensions etc.) and EXAP rules form a standardized technical agreement on the parameter
changes.
The fundamental concept of EXAP is the development of safe methods that provide extensions to the
scope of the tested product while maintaining the required classification for the product. Test reports
constitute the basis of an EXAP report.
This document makes reference to ‘extended application standards’ throughout; wherever this term is
used it refers to either a standard prepared by CEN/TC 127 ‘Fire safety in buildings’ or the relevant
product standard which includes information on extended application.
The European system currently permits extended application rules to be included in technical
specifications. CEN Technical Committees and EOTA Working groups producing these rules are asked to
seek the guidance of CEN/TC 127 to ensure that their rules comply with standards prepared by
CEN/TC 127. In cases where extended application rules in harmonized EN product standards and ETAs
do not comply with standards prepared by CEN/TC 127 the CEN BT are informed.
This document does not cover the incorporation of the product into the construction works that is
justified by national rules.
Expert judgements (i.e. an opinion that is not considered/covered by an EXAP standard and only based
on the experience of one individual) do not form part of this process.
