NF P92-501 Fire test to Building materials (M Class)- Test Method：
NF P 92-501 M rating test Classify the fire test to M1, M2, M3, M4，M0 is the highest class
Note the following points in the test
> Flame height
> Combustion duration
Cut the sample to the close room by the horizontal angle of 45 degrees, with 30 kW/m2 heat radiation exposure to the minimum sample surface. placed above and below the ignition flame with the sample, it can burn any volatile gases released. After the fire, remove the flame ignited from sample, the flame will goes out.
Classification (NF P 92-507):
Classification (NF P 92-507):
M1 - Non-flammable 0 < q < 2.5
M2 - The low flammability 2.5 < q < 15
M3 - Moderately flammable 15 < q < 50
M4 –Combustible q > 50
