EuroClass EN13501-1:2007+A1:2009

EuroClass EN13501-2

EuroClass EN13823 (SBI)

Single Burning Item test EN 13823. The SBI test is a relatively new fire test method developed specially for the Euroclass system. The test is based on a fire scenario of a single burning item, e.g. a wastebasket, located in a corner between two walls covered with the lining material to be tested. The SBI test is used for construction products excluding floorings.

The SBI test was developed by a group of European fire laboratories on the basis of the specifications defined by a group of European fire regulators. The development work included the design of a prototype, the installation of test facilities, the determination of the accuracy of the method, and the production of data needed to finalise the classification system.
