Introduction:

The Single Burning Item (SBI), is a method of test for determining the reaction to fire behavior of building products (excluding floorings) when exposed to the thermal attack by a single burning item (a sand-box burner supplied with propane). The specimen is mounted on a trolley that is positioned in a frame beneath an exhaust system. The reaction of the specimen to the burner is monitored instrumentally and visually. Heat and smoke release rates are measured instrumentally and physical characteristics are assessed by observation.



Testing Results:
 

1. Average rate of heat release[RHRav(t)]
2. Total Heat Release[THR(t)]
3. ***0 * [RHRav(t)/(t***0)]
4. Fire Growth Rate Index[FIGRA]
5. Total Heat Release[THR**0s]
6. Occurrence of Lateral Flame Spread
7. RSPav(t)
8. Total Smoke Production[TSP(t)]
9. ****0 * [RSPav(t)/(t***0)]
10. Smoke Growth Rate Index[SMOGRA]
11. Total Smoke Production[TSP**0s]
