ENV 1187:2002. That standard incorporates four distinct test methods that correspond to different fire hazard scenarios. There is no direct correlation between the test methods and hence no generally acceptable hierarchy of classification between them. Products classified in a given class are deemed to satisfy all the requirements of any lower class for the same test method/fire hazard scenario. The classes with their corresponding fire performance are given in Table1. 5 Test methods 5.1 General The four test methods given in ENV 1187 are those to be used for classification purposes for roofs/roof coverings. The selection of the tests to be carried out is specified in 6.3. The classification parameters, the classes and the corresponding criteria are specified in Clauses 8 and 9. 5.2 Test 1: Method with burning brands The test evaluates the performance of a roof under the conditions of thermal attack with burning brands. The performance includes the fire spread across the external surface of the roof, the fire spread within the roof and the fire penetration. 5.3 Test 2: Method with burning brands and wind The test evaluates the performance of a roof covering under the conditions of thermal attack with burning brands and additional wind. The performance includes damaged length both on the roof covering and in the substrate. 5.4 Test 3: Method with burning brands, wind and supplementary radiant heat The test evaluates the performance of a roof under the conditions of thermal attack with burning brands, additional wind and radiant heat. The performance includes the external fire spread and the fire penetration. SIST EN 13501-5:2006+A1:2009
