Standards:
GB/T 20284-2006 Building products-single burning item BS EN 13823 Reaction to fire tests for building products — Building products excluding floorings exposed to the thermal attack by a single burning item
Applications:
The single burner (SBI) is used to determine the performance of building materials (excluding flooring materials) under the condition of single combustion heat attack.
Product Information:
The sample is placed on a moving cart under the exhaust system, and the combustion reaction of the specimen is automatically visible. Mechanical properties are evaluated by calculating the heat release rate (H.R.R) and the smoke release rate (S.R.R), while other physical properties are evaluated by visual observation.
SBI's Fire Growth Rate Index (FIGRA) is the most representative measure factor. In addition, representative measurement factors are oxygen consumption, CO, CO2 generation and smoke growth rate index (SMOGRA). The maximum heat release rate can reach 1MW.
Systems:
Ignition system
10kV spark ignition, equipped with a safety ceasefire device. The igniter is automatically positioned by a lever connected to the closing mechanismSBI's Fire Growth Rate Index (FIGRA) is the most representative measure factor. In addition, representative measurement factors are oxygen consumption, CO, CO2 generation and smoke growth rate index (SMOGRA). The maximum heat release rate can reach 1MW.
