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.

4 Developing extended application standards
4.1 General
The following gives guidance on the minimum rules on how to write an EXAP standard. An extended
application standard shall on principle be based on a sufficient number of relevant tests and/or common
scientific interpretation.
The relevance of the supporting evidence for any particular rule shall be agreed by the task group
preparing the EXAP standard.
Additional requirement on test methods not being part of EN test standards should be fully described in
the EXAP standard and should only be included for the purpose of generating additional data for the
purpose of extending the scope of application.
All supporting documentation is considered to be prepared in a way that confidentiality is ensured. The
content of the supporting documentation should be summarized in an annex including reasoning to
validation of the rule. (e.g. EN 1634-1:2014+A1:2018, Annex C).
4.2 Minimum content of an EXAP standard
4.2.1 General
In addition to the chapter requested in every standard by the CEN rules the following recommendation
are specified.
4.2.2 Scope
The scope of the EXAP standard shall specify that it will provide guidance and rules to a type of product
in order to extend the application of the available test results.
The scope shall specify the type of product covered and when relevant the type of products not covered.
4.2.3 Normative references
The paragraph on normative references shall follow the CEN rules and shall list the standards referenced
to in the document.
4.2.4 Terms and definitions
The paragraph on terms and definitions shall follow the CEN rules and shall list the term and references
referenced to in the document.
4.2.5 Technical justification on which the EXAP rule is based
A description of the technical justification shall be presented in an annex of the standard (e.g. background
document as used for EUROCODES) and/or when relevant a bibliography shall be added to the standard.
The objective of the justification shall be considered in a way that the application of the EXAP rule shall
be repeatable and reproducible and shall not give room for interpretations.
The Technical procedure shall be supported by technical data or calculation.
4.2.6 Evidence for supporting EXAP rules
Suitable evidences required to support the EXAP rules is listed below:
— test data from EN standards;
— ad hoc test data;
— test data from national standards;
— established scientific and engineering principles;
— background information, such as tests performed on a previous version of the standard can be
considered for the purpose of the justification of the proposed rules.
4.2.7 Parameters / factor and rules (described in other parts of the standard)
The set of rules shall be expressed in a shape of a table (Table 1) gathering the parameters/factors to be
taken into account.
Table 1 — Example of table
Construction Factor/Variation Influence of Limitation Rules see
parameter factor/variation on Clause: xxx
performance
characteristic
(R,E,I,S…)
If the EXAP standard contains parameters and rules in the shape of chaptering, it is mandatory to use this
chaptering in the EXAP report.
4.2.8 Limitation
The EXAP standard shall declare any limitations.
4.2.9 Combination of extended application rules
The EXAP standard shall provide justification and/or limitations of the combination of any rules.
4.2.10 Annex
The annex shall contain the technical justification of the defined rules including a detailed description of
the supporting data.
5 Extended application reports - Role of extended application in the
classification process
There are two possible routes to obtaining a fire classification. The first one is to undertake fire tests in
accordance with the relevant EN fire test methods given in one of the parts of EN 13501 series of
standards. From the test report(s) obtained, a classification report can be prepared. The second one
refers to an extended application carried out in accordance with the relevant EN extended application
standard. From this process an extended application report is prepared in conformity with this
document.
An extended application report is used like a test report as a basis for preparing a classification report.
This process is illustrated in Figure 1.
Figure 1 — Role of extended application in the classification process
6 Principles of establishing the field of application
6.1 General
Following a test there are two fields of application that can be derived from the result, direct field of
application and extended field of application.
6.2 Direct field of application
6.2.1 Reaction to fire
Direct application of results from reaction to fire tests is undertaken in accordance with EN 13501-1
using results from the relevant EN test methods applicable for the definition of the classification and
taking into account information on substrates given in EN 13238 and information in CEN/TS 15117 and
any other relevant European Technical Specification.
