Fire classification for roofs/roof coverings acc. EN 13501-5
According to the European standard EN 13501-5:2016, the fire behavior of roofing and roof coverings is classified. The associated test procedure determines the resistance to flying sparks and radiant heat. This serves in particular to simulate an outbuilding on fire, the flames of which could flash over onto the building with the roofing to be classified. The associated test method t4 essentially provides for two tests:
- The test specimen is exposed to a 23 cm gas flame for one minute. Fire duration and spread are then evaluated.
- The test specimen is exposed to four radiant heat panels for 60 min and also to an open gas flame for a short time (see picture). It is then evaluated whether the heat exposure was able to penetrate the test specimen.
