CEN/TC 127/WG 5 - Roofs

This document gives guidance on the process and development of extended fields of application using test results obtained from CEN/TS 1187, tests 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 document 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 Annex A, Annex B, Annex C and Annex D for CEN/TS 1187, tests 1 to 4 respectively.

This Technical Specification specifies four methods for determining the performance of roofs to external fire exposure. The four methods assess the performance of roofs under the following conditions:
a)   test 1 - with burning brands;
b)   test 2 - with burning brands and wind;
c)   test 3 - with burning brands, wind and supplementary radiant heat;
d)   test 4 - with two stages  incorporating burning brands, wind and supplementary radiant heat.
The tests assess the fire spread across the external surface of the roof, the fire spread within the roof (tests 1, 2 and 3), the fire penetration (tests 1, 3 and 4) and the production of flaming droplets or debris falling from the underside of the roof or from the exposed surface (tests 1, 3 and 4).
Tests 2 and 3 are not applicable to geometrically irregular roofs or roof mounted appliances, e.g. ventilators and roof lights.
NOTE   The four tests listed above do not imply any ranking order. Each test stands on its own without the possibility to substitute or exchange one for another.
