Extended application reports on the fire performance of construction products and building elements
This European Standard gives the procedures for preparing reports on the extended application process using the results of reaction to fire tests, fire resistance tests 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. This standard 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. In some cases, where a standard is not yet published, relevant bodies may issue recommendations for use by Notified Bodies in attestation procedures for CE marking under the Construction Products Directive (CPD), http://ec.europa.eu/enterprise/newapproach/nando/. 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 harmonised EN product standards and ETAs do not comply with standards prepared by CEN/TC 127 the CEN BT should be informed.
Berichte zum erweiterten Anwendungsbereich bezogen auf das Brandverhalten von Bauprodukten und Bauarten
Diese Europäische Norm legt die Verfahren für die Anfertigung von Berichten zu dem Prozess der erweiterten Anwendung der Ergebnisse von Prüfungen zum Brandverhalten, von Feuerwiderstandsprüfungen oder von Prüfungen an Bedachungen mit Brandeinwirkung auf von außen fest, die für die Klassifizierung von Produkten und Produktfamilien nach den verschiedenen Teilen der Normenreihe EN 13501 durchgeführt wurden.
Diese Europäische Norm verweist durchweg auf „Normen des erweiterten Anwendungsbereichs“, wo auch immer dieser Begriff angewendet wird, bezieht er sich auf eine andere durch CEN/TC 127 „Baulicher Brandschutz“ erarbeitete Norm, die Angaben zum erweiterten Anwendungsbereich einschließt. In einigen Fällen, in denen noch keine Norm veröffentlicht wurde, ist eine entsprechende Empfehlung der EC-Group of Notified Bodys (GNB) Fire Sector Group (FSG) für die Anwendung durch notifizierte Stellen zur Bestätigung der CE Kennzeichnung nach der Bauproduktenrichtlinie (BPR)verfügbar.

Das Europäische System erlaubt gegenwärtig Regeln des erweiterten Anwendungsbereichs in Technischen Spezifikationen. Technische Komitees, die diese Regeln erarbeiten, sind gebeten, die Anleitung 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 des erweiterten Anwendungsbereichs in technischen Spezifikationen nicht den von CEN/TC 127 erarbeiteten entsprechen, muss CEN BT informiert werden.
Rapports d'application étendue des performances au feu des produits et éléments de construction
La présente Norme européenne indique les procédures à suivre pour la rédaction des rapports d'application étendue. Ces rapports s’appuient sur les résultats des essais de réaction au feu, de résistance au feu ou encore d’exposition des toitures à un feu extérieur, entrepris pour le classement au feu des produits et des familles de produit, conformément aux diverses parties de l'EN 13501.
La présente norme 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 produit appropriée, laquelle inclut des informations concernant l'application étendue. Dans certains cas, lorsqu'une norme n'est pas encore publiée, une Recommandation appropriée, issue du Groupe d'Organismes Notifiés (GNB) EC - groupe du secteur feu (FSG) est émise par les Organismes Notifiés pour l'attestation de conformité pour le marquage CE au titre de la Directive sur les produits de construction (CPD), http://ec.europa.eu/enterprise/newapproach/nando/.
Le système européen permet actuellement l'intégration des règles d'application étendue dans les spécifications techniques. Les comités 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. Dans certains cas, lorsque les règles d'application étendue présentes dans les spécifications techniques ne sont pas conformes avec les normes élaborées par le CEN/TC, le BT du CEN doit en être informé.
Poročila za razširjeno uporabo, ki se nanašajo na ognjevarne lastnosti gradbenih proizvodov in elementov stavb
Ta evropski standard podaja postopke za pripravo poročil za postopek razširjene uporabe z uporabo rezultatov odzivov na preskuse požarne varnosti, preskuse zaščite pred ognjem in izpostavljenosti na zunanji ogenj ter preskusov streh, izvedenih za klasifikacijo ognja za izdelke in družine izdelkov v skladu z različnimi deli EN 13501. Ta standard se sklicuje na »standardne za razširjeno uporabo« v vsem besedilu; ne glede na to, ali je ta besedna zveza uporabljena, se nanaša na bodisi standard, ki ga je pripravil CEN/TC 127 »Požarna varnost v stavbah«, bodisi ustrezne standarde o izdelkih, ki vključujejo informacije o razširjeni uporabi. V nekaterih primerih, če standard se ni objavljen, lahko ustrezni organi izdajo priporočila, ki jih uporabljajo priglašeni organi v postopkih potrjevanja za oznako CE po Direktivi o gradbenih izdelkih (CPD), http://ec.europa.eu/enterprise/newapproach/nando/. Evropski sistem trenutno dopušča, da so pravila za razširjeno uporabo vključena v tehnične specifikacije. Tehnični odbori CEN in delovne skupine EOTA, ki ustvarjajo ta pravila, so zaprošeni, da prosijo CEN/TC 127 za navodila z namenom zagotoviti, da so njihova pravila skladna z standardi, ki jih pripravi CEN/TC 127. V primerih, kjer pravila razširjene uporabe v usklajenih EN standardih o izdelkih in ETA niso v skladu s standardi, ki jih je pripravil CEN/TC 127, je potrebno CEN BT obvestiti.

EN 15725:2010 (E) 4 Introduction A construction product and 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. NOTE A building element is understood to be a defined construction component, e.g. wall, partition, floor, roof, beam or column. Fire test methods may not include any information on direct application, the result obtained in the test is that which is reported. In a separate exercise it is possible to extend the field of application of the individual test results to a variation of the values of the different product parameters. This process of extended application uses rules which are essentially based on a worst case scenario and interpolation techniques. All information on extended field of application of reaction to fire results is given in CEN/TS 15117. 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. To achieve this, extended application standards for the various elements are under development. Rules for extended application of results from external fire exposure to roof tests are also under development. SIST EN 15725:2010

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. From the test report(s) obtained, a classification report can be prepared. Secondly an extended application can be undertaken using test reports and other relevant data, and carried out in accordance with the relevant EN extended application standard. From this process an extended application report is prepared in conformity with this standard.
An extended application report is equivalent to a test report in that it then forms the basis for preparing a classification report. This process is illustrated in Figure 1.

EN 15725:2010 (E) 9 5 Principles of establishing the field of application 5.1 General Following a fire test there are two fields of application that can be derived from the result, direct field of application and extended field of application. 5.2 Direct field of application 5.2.1 Reaction to fire Direct application of results from reaction to fire tests is undertaken in accordance with
EN 13501-1:2007+A1 using results from the relevant EN classification test methods and taking into account information on substrates given in EN 13238 and information in CEN/TS 15117 and any other relevant European Technical Specification. 5.2.2 Fire resistance The rules governing the direct field of application of results from fire resistance tests are given in the individual test methods.
5.2.3 External fire exposure to roofs The rules governing the direct field of application of results from external fire exposure to roof tests are given in EN 13501-5:2005+A1. 5.3 Extended field of application 5.3.1 General principles Extended application shall be undertaken by the laboratory which has carried out the relevant fire tests. If test results are to be used from more than one laboratory, then the extended application shall be undertaken by one of these laboratories and consultation should be made with the other laboratories.
NOTE When extended application is intended to be used for CE marking purposes the intervention of a Notified Body is mandatory.
When a Notified Body is requested to produce an EXAP Report which requires the consideration of evidence from third parties (e.g. test reports, DIRAP reports, other EXAP reports, etc.), such evidence shall only be used when permission has been obtained from the original sponsor/owner of that evidence.
Extended application shall be undertaken in accordance with the relevant EN extended application standard. Extended application shall be based on test methods in accordance with the relevant European standards or ETAG, which may be supplemented by: documents mentioned in Figure 1 5.3.2 Reaction to fire Information on undertaking extended application from the results of reaction to fire tests and an explanation of the influence of product and end use parameters on reaction to fire performance is given in CEN/TS 15117.

EN 15725:2010 (E) 10 5.3.3 Fire resistance 5.3.3.1 General The extended field of application analysis is an additional process that has to be applied for and is not granted automatically following a fire resistance test. An extended field of application analysis is required when the application of the element differs from the test specimen and is not covered by the direct field of application. Examples for the variations to be considered when performing an extended application are identified in 5.3.3.2. Details of undertaking extended application of results of fire resistance tests are covered in the relevant European standards for extended application and other documents referred to in Figure 1.
