作者:admin    发布于:2021-12-29 09:13:44    文字:【】【】【

1. NF P92-501 Fire test to Building materials M classification - Standard
NF P92-501: Building materials-Reaction to fire tests, radiation test used for rigid material or flexible materials thickness more than 5mm.

2. NF P92-501 Fire test to Building materials M classification - Test Method
Specimens of the product are mounted in an enclosed chamber at an angle of 45° to the horizontal and exposed to thermal radiation (30kW/m2) on their lowest surface, the test duration 20 minutes.

The materials is classified M1 to M4 according to the q index (NF P92-507)
M1 - Non flammable           q < 2.5
M2 - Low flammability        q < 15
M3 - Moderately flammable    q < 50
M4–flammable                q ≥50

If specific, unusual, specimen behaviour is observed additional supplementary tests (NF P 92-504 or NF P 92-505) may be required.
