BAS EN 13501-5+A1:2010

This European Standard provides the fire performance classification procedures for roofs/roof coverings exposed to external fire based on the four test methods given in ENV 1187:2002 and the relevant extended application rules. For the classification of a roof/roof covering, only those test methods and those application rules need to be applied for which the corresponding classification is envisaged. Products are considered in relation to their end use application. NOTE The distinction between roofs with a steep slope and facades, in terms of the test and classification standard to be applied, may be subject to national regulations. General information on the four test methods in ENV 1187:2002 is given in Annex A.
