The Euro classification construction products directive enables various performance classes (A to F) to be established for wall and roofing products and floor-coverings.  The “Single Flame Source Test" is built in accordance with BS EN 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.

The dimensions of the test specimens shall be 250mm long by 90mm wide.
