External fire exposure of roofs and roof coverings - Extended application of test results from CEN/TS 1187

CEN/TS 16459 gives guidance on the process and development of extended fields of application using test results obtained from CEN/TS 1187 test 1 to 4, and included in test reports, and other relevant information in order to evaluate and classify the performance of roofs/roof coverings. This Technical Specification provides a methodology to consider the possible effect(s) on classification to EN 13501-5 from single or multiple changes to the individual product and end-use application parameters of the roof/roof covering. Specific application guidance is given in Annexe A, Annex B, Annex C and Annex D for CEN/TS 1187 tests 1 to 4 respectively.

Beanspruchung von Bedachungen durch Feuer von außen - Erweiterter Anwendungsbereich der Prüfergebnisse aus CEN/TS 1187

Das vorliegende Dokument liefert einen Leitfaden für den Prozess und die Entwicklung der erweiterten Anwendungsbereiche unter der Anwendung der in den Prüfungen 1 bis 4 nach CEN/TS 1187 erzielten und in Prüfberichten enthaltenen Prüfergebnisse und anderer einschlägiger Informationen zur Bewertung und Klassifizierung der Leistungsfähigkeit von Dächern/Bedachungen. Dieses Dokument legt eine Vorgehensweise fest, mit der die möglichen Auswirkungen einer einzelnen oder mehrfachen Änderung der einzelnen Produktparameter und Endanwendungsparameter des Daches/der Bedachung auf die Klassifizierung nach EN 13501 5 in Betracht zu ziehen sind.
In den Anhängen A bis D werden spezifische Leitlinien für die Anwendung der Prüfungen 1 bis 4 nach CEN/TS 1187 gegeben.

Exposition des toitures et des couvertures à un feu extérieur - Application étendue des résultats d'essai de la CEN/TS 1187

Le présent document donne des lignes directrices concernant le processus et le développement de champs d'application étendus en utilisant les résultats d'essai obtenus par les essais 1 à 4 de la CEN/TS 1187, et inclus dans des rapports d'essai, ainsi que d'autres informations pertinentes afin d'évaluer et de classer les performances de toitures/couvertures. Le présent document fournit une méthodologie permettant d'étudier le ou les effets éventuels sur le classement selon l'EN 13501-5 de modifications simples ou multiples apportées aux produits individuels et aux paramètres d’utilisation finale de la toiture/couverture.
Des lignes directrices d'application spécifiques sont données respectivement dans les Annexes A à D pour les essais 1 à 4 de la CEN/TS 1187.

Introduction

Fire tests on individual roofs/roof coverings are carried out in accordance with CEN/TS 1187. The results from

these tests can then be classified in accordance with EN 13501-5.

In order to derive classifications for similar roofs/roof coverings based on the data determined from

CEN/TS 1187, additional rules are needed.

These rules are direct application rules or extended application rules. Rules within the direct field of

application of test results are given in EN 13501-5 (these rules correspond to CEN/TS 1187).

This document outlines a procedure to develop rules for extended application and lists application rules which

have already been developed in Annexes A to D for test methods 1 to 4 from CEN/TS 1187, where Annex A is

related to test method 1, Annex B relates to test method 2, and so forth.

Annexes A to D have been developed based upon the available information and the roof systems in the

market. The objective of this document is to provide a methodology for optimising the number of tests required

to cover the maximum field of application.

Whilst special attention has been focused on roofs typically comprising a support deck/substrate, vapour

barrier, insulation layer(s), membranes/roof coverings, there will be occasions when other separating layers or

intermediate layers will be needed to satisfy other roof characteristics. These layers should be included in the

consideration of the roof/the roof covering being classified.

NOTE Tests 1, 3 and 4 are carried out on a roof construction, whereas test 2 is done on a roof covering with its

substrate below.

The decision route from the diagram below shows ways to determine which procedure to follow.

The solid line is compulsory, whereas the dotted line is optional.

1 Scope

This Technical Specification gives guidance on the process and development of extended fields of application

using test results obtained from CEN/TS 1187 test 1 to 4, and included in test reports, and other relevant

information in order to evaluate and classify the performance of roofs/roof coverings. This Technical

Specification provides a methodology to consider the possible effect(s) on classification to EN 13501-5 from

single or multiple changes to the individual product and end-use application parameters of the roof/roof

covering.

Specific application guidance is given in Annexe A, Annex B, Annex C and Annex D for CEN/TS 1187 tests 1

to 4 respectively.
