Single-Flame Source Test - Ignitability Apparatus – ISO 11925
The Euroclassification construction products directive enables various performance classes (A to F) to be established for wall and roofing products and floor-coverings. Higher classifications are achieved from good performances in the SBI apparatus, for roofing and wall lining products, or in Flooring Radiant Panel test for flooring products.
"The Single Flame Source Test" is built in accordance with "ISO 11925-2: Reaction to fire tests for building products - Part 2: Ignitability when subjected to direct impingement of flame". The apparatus is based on the German Kleinbrenner method for determining ignitability of building products in the vertical orientation .by direct small flame impingement under zero impressed irradiance.
Single flame source test is applicable to:
> ISO 11925-2: Reaction to fire tests for building products - Part 2: Ignitability when subjected to direct impingement of flame
> DIN 4102-1: Fire behaviour of building materials and elements Part 1: Classification of building materials Requirements and testing
> GB/T 8626: Test method of flammability for building material
> EN 13501-1: Fire classification of construction products and building elements-Part1: Classification using data from reaction to fire tests
