Single Burning Item (SBI) The Single Burning Item (SBI) test EN 13823 is one of the tests in the Euroclass system.

It is the main reaction to fire test for building products and investigates the response of a product in a corner configuration when it is exposed to a thermal attack typifying fire involving a single burning item.

It was the FIRE design of the SBI equipment that formed the cornerstone for the extensive European Commission sponsored 'round-robin' exercise that was carried out to validate this test method. It is relevant to classification of the product into classes A2, B, C or D as set out in Commission Decision of 8th February 2000 - implementing Council Directive 89/106/EEC. EN 13823 excludes flooring materials.
