After decades of dealing with fire classification systems in individual countries or regions, the construction industry can finally benefit from a unified European fire testing standard accepted by all EU member states.

The Single Burning Project (SBI) EN 13823 test is a coordinated standard for the fire performance testing of building products. The product based on this test result is classified according to the European standard EN 13501-1.

The performance of the polycarbonate endurance board using the SBI testing method was excellent, and it received an excellent rating according to EN 13501-1 classification. The best classification of possible combustible materials for Class B S1 and D0 was obtained from polycarbonate endurance plates and solid expression with a thickness of 6mm. Polycarbonate solar panels are classified as b-s1/S2, d0 based on their thickness.

The SBI test is an integrated testing method from France, the United Kingdom, and Germany, based on the existing full-scale room corner fire test method (ISO9705). With a unified system introduction, the construction industry provides several testing methods based on individual countries or regions that can avoid being expensive and time-consuming.

SBI tests fire growth coefficient (FIGRA), lateral flame spread (LSF), total heat release (Thr), smoke growth rate (smoke generation rate index), and total smoke production (TSP). These parameters provide necessary information to establish regulatory agencies and fire engineers to evaluate the superior response of polycarbonate endurance panels to fire characteristics compared to traditional building materials and other engineering plastics, such as PMMA.
