What is an SBI or Single Burning Item test?
The SBI test replicates a small fire in the corner of a room, with the room corner being constructed from the product to be tested. A flame from a burner with a known output is applied to the product. The products of any resulting combustion are measured, and these allow calculation of the energy that the product has contributed to the fire. Classification will be assessed on the rate of energy production, the total energy produced over a certain period of time, lateral spread of flame and the observation of any flaming particles that may fall from the product.
