The EN 13823 Single Burning Item (SBI) tester is a critical European standard (EN 13823:2020+A1:2022) within the Euroclass fire classification system (EN 13501-1). This equipment evaluates the fire reaction performance of building products (excluding floorings) by measuring heat release rate, smoke production, and flame spread under controlled conditions.

EN 13823:2020+A1:2022: Reaction to fire tests for building products - Building products excluding floorings exposed to the thermal attack by a single burning item (SBI).

• Wall and ceiling linings: gypsum boards, wood panels, metal/plastic composite panels, fiber cement boards
• Insulation materials: mineral wool, polystyrene foam, polyurethane foam, glass fiber, rock wool
• Coatings and treatments: fire-retardant paints, varnishes, wallpapers, decorative films
• Facade systems: ETICS, curtain wall panels, aluminum composite panels
• Duct and linear products: pipe insulation, cable trunking covers, ventilation duct linings
• Composite products: sandwich panels, honeycomb panels, laminates, PVC/acrylic sheets

The test specimen (two vertical wings at right angles) is exposed to a propane flame (30.7 ± 2.0 kW) from a main burner. The 20-minute test evaluates heat release, smoke production, flame spread, and combustion droplets/particulates.
