Single Burning Item (SBI)
The Single Burning Item (SBI) is a method to determine the reaction to fire of building products(excluding floorings) by exposed to a single burning item(propane fueled sand-box burner). The sample is placed in the corner of the trolley and the trolley is positioned underneath the exhaust system. Sample reaction to fire is visible by the side observation window, and the heat release (THR600s), smoke production(TSP600s), FIGRA0.2MJ, SMOGRA, LFS are calculated and reported during the test.

SBI is the major test for European building products classification assessment (EN 13501-1), the classes range from A to F.

Single Burning Item (SBI) consists of
• Trolley, which mounts the specimen, with primary sand-box burner on the corner.
• Test room, with trolley position frame, secondary sand-box burner on the support frame. A proper observation window should be on side of the wall. Hood with baffles and collector fitted to the room above the frame.
• Stainless steel ducting, with instrumented section, which has combustion gas sampling probe, bi-directional probe, thermocouples, and light attenuation system for smoke measurement.
• Gas analysis rack, with gas sampling system, gas analysis sensor, and data acquisition system.
• Combustion gas sampling system, consisting of 3-stages filters (accuracy up to 0.5 microns), refrigerated cold trap, diaphragm pump, moisture trap.
• Propane mass flow controller for sand-box burner, accuracy up to ±1.5% F.S.
• Oxygen analyzer, paramagnetic type with the range of 0 to 25%. SERVOMEX® or ABB® gas analyzer is optional.
• Carbon dioxide analyzer, NDIR type with the range of 0-1% & 0-10%. SERVOMEX® or ABB® gas analyzer is optional.
