BS EN 13823 Fire Tester SBI Single Burning Items For Building Materials

BS EN 13823 Single Burning Items Product Introduction:

The Single Burning Instrument (SBI) is used to evaluate the performance of building materials (excluding flooring materials) under conditions of single burn heat attack. The sample is placed in the flame in a sliding box (methane sandbox burn box), located below the exhaust pipe. During the combustion process, the reaction of the sample is monitored both mechanically and visually. The heat and smoke release rates are measured by the instrument, while the performance of the material is evaluated by observation.
