Fire Testing on the Polymeric Bituminous Roof Covering with Heat Insulation
Keywords:heat transfer, radiation, fire tests, roofing, combustibility.
Analysis of experience of other countries in the field of fire testing and analysis of the documents prepared by CEN resulted in the review of real fires and test methods used in Lithuania. As a consequence of that the fire test method for roof covering with insulation material exposed to external fire is proposed. The combustible roof covering with insulation materials is tested. The maximum lengths of affected surfaces of polymeric bituminous and insulation material were measured, the maximum temperatures of burning products were estimated as well as the speed of flame spread. It has been determined, that the temperatures along the specimen of the roof covering system become dangerous in relation to the combustibles.
