Experimental comparisons in facade fire testing considering SP Fire 105 and the BS 8414-1

摘要

A comparison between full-scale facade fire tests where SP Fire 105 and BS 8414-1 were used regarding repeatability and the use of modeling to discern changes in the setups is presented. Two test series according to BS 8414-1 were repeated outside using the same facade systems on 2 different days, whereas for the SP Fire 105 a set of common facade systems in Sweden were tested indoors. In particular, the results show that the wind around the test setup may have a significant impact on the tests and that the heat exposure to the facade surface will depend on the thickness of the test specimen where an increased temperature in front of the facade, and a decreased temperature on the facade 2.1 m above the fire room, is observed experimentally. The heat exposure to the test specimen varies to a more limited extent when an uncontrollable free burning fire source is used (in this study heptane and wood, respectively) and that this variation increases when wind is present.
