NF 92501

Fire test To Building Materials- French Standard: NF P92-501

 


1.       NF P92-501 Fire test to Building materials - Standard Title

 

NF P92-501: Safety against fire: Building materials – Reaction to fire tests. used for rigid material or flexible materials thicker than 5mm

 

2.       NF P92-501 Fire test to Building materials - Standard Brief

 

NF P 92-501 Contain fire tests method of construction and decoration materials.

 

3.       NF P92-501 Fire test to Building materials - Products Scope

 

Rigid material

Rigid substrate materials (floorings, etc.)

Flexible materials thicker than 5mm

> Etc

 

4.       NF P92-501 Fire test to Building materials - Test Method

 

NF P 92-503 Class the fire test from M0 to M4M0 is the highest class

Note the following points in the test
Combustion duration

Flame height

 

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):

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
