EN ISO 92391 Flooring Radiant Panel
The burning behaviour of floorings, including any substrates if used, is tested according to EN ISO 92391 in a closed chamber using a radiant panel heat source.
The FTT Flooring Radiant Panel (FRP) evaluates the critical radiant flux below which flames no longer spread over a horizontal surface.
This test method is used to measure the critical radiant flux of floor covering systems exposed to a flaming ignition source in a graded radiant heat environment, within a test chamber.
A smoke measuring system according to DIN 50055 is mounted on a separate frame at the exhaust stack. It can also be used to measure this same critical radiant flux for exposed attic floor cellulose insulation.
The FTT Flooring Radiant Panel can also comply with ASTM E648, ASTM E970, NFPA 253 and DIN 4102 Part 14.
The Critical Heat Flux at extinguishment value (CHFvalue) is the incident heat flux at the specimen surface at the point where the flame ceases to advance and may subsequently go out.
For Classification purposes, the CHFvalues in kW/m2
Level are shown in Table 5. for each Hazard
