fuel tests, calculated burning rates were lower than those observed for similarly sized fires in the open. Started immediately after ignition, the sprinklers reduced the maximum ceiling arch temperatures from, but the steam apparently pushed burning gases and gasoline vapors into adjacent tunnel sections, where they continued to burn.

. As compared to fire tests performed with gasoline, diesel oil, and n-heptane, special attention must be paid to two factors that heavily influence the smoke development and the dispersal of smoke in fires involving real road vehicles: • The materials used for the vehicle construction (without load)

Design fire scenarios and associated design fire curves were proposed by UPTUN WP2, and used as input to other work packages within UPTUN. These design fires can also be used in more general terms since they are based on current knowledge about fire scenarios as well as information created within the UPTUN project.

A characteristic of the UPTUN experiments is the use of real road and rail vehicles as fire loads. The heat release rate of such fires was one of the unanswered fundamental questions for fire life safety systems design.
