EN ISO 9239-1:2010 revised EN ISO 9239-1: 2002 floor-covering Reaction to fire tests

ISO EN 9239-1: Reaction to fire tests-Horizontal surface spread of flame on floor-covering systems-Part 1: Flame spread using a radiant heat ignition source.

The method standard is similar with GB/T 11785:2005

This standard specifies the performance assessment of the ground material combustion method. The method is burning in the test box, with a small flame ignited horizontally and exposed to 30 ° tilt in the heat radiation plate surface material, to assess their ability to fire spread. This method is suitable for a variety of ground materials (including substrate) of the combustion performance.

Based on the thermal radiation curve, the observed flame propagation distance converted Sample did not ignite or flame spread not more than 110mm, it's critical heat flux ≥ 11 KW/m², sample flame spread distance of more than 910mm, it's critical heat flux ≤ 1.1 KW/m², calculating the critical heat radiation, accurate to 0.2 KW/m².
