摘要

Knowing the fire behaviour of roofs is important when deciding on the fire safety strategy andrnrisk analysis for buildings. Consequently appropriate fire test methods, which provide informationrnabout the fire behaviour of roofs, are needed.rnOver the years many different test methods have been developed which address the fire behaviour ofrnroofs. Some are developed by national standardisation organisations such as ASTM in the US or DINrnin Germany while others are developed by the insurance industry. For each test method the results arernlinked to the fire scenario, which the test method is attempting to simulate. Some of the existing testrnmethods focus only on surface spread of flame on the top of the roof, others address both surfacernspread of flame and penetration of fire from above, as well as the issue of fire spreading through thernroofing system when exposed to a fire from within the building.rnThis paper provides a thorough review of fire test methods for roof assemblies, which currently arernavailable in Europe and North America. The underlying fire scenario, the test parameters and the testrnresults will be discussed.
