NF P92-501: Safety against fire: Building materials – Reaction to fire tests. used for rigid material or flexible materials thicker than 5mm
NF P92-501: Fire Safety: Construction Materials - Combustion Reaction. Rigid materials and flexible materials with thickness greater than 5mm

NFP92-501 Fire Safety: Class M Fire Testing of Building Materials – Standard Overview:

NF P 92-501 This regulation contains test methods for the fire performance of building and decorative materials

NFP92-501 Fire Safety: Class M Fire Test for Building Materials - Scope of application of the standard:

Rigid material
Materials for rigid base materials (floors, etc.)
materials with thickness greater than 5mm

NFP92-501 Fire Safety: Class M Fire Test for Building Materials - Standard Analysis:

NF P 92-503 is divided into levels M0 to M4 for fire protection testing, with M0 being the highest level.

Pay attention to the following points during the test：

Burning duration
Height of the flame

The sample is inserted into a closed chamber at an angle of 45 degrees to the horizontal and 30 kW/m2 of thermal radiation is exposed to the lowest surface of the sample. Pilot flames are placed above and below the sample to ignite any volatile gases released. After ignition, remove the ignition flame from the sample and the sample flame will extinguish.
