NF P 92-507 Fire Safety - Building - Interior Hardware Materials - Classification According to Reaction to Fire

The NF P92-507 standard, a French standard, describes the classification method of construction and furnishing products according to their reaction to fire. In the event of a fire, it is very important to protect people's lives first and foremost. The building must be evacuated on time. At this point, the factors that determine the time are the selected building materials and the behavior of these materials during exposure to fire. To facilitate and optimize this process, a set of standards has been developed that define the behavior of different materials in response to fire.

Building materials and products are classified differently according to how they react to fire. In this classification, the moment when flammable materials begin to burn, raising the ambient temperature and increasing the rate of spread is crucial.

According to fire test results, fire classification is made as follows:

• M1 value is not flammable (0
• M2 value indicates low flammability (2.5
• M3 value indicates moderate flammability (15
• M4 value indicates flammability (q>50)

If specific and unusual sample behavior is observed during testing, additional complementary testing may be required. These tests are included in other French standards that are close to this standard and used for similar purposes:

• NF P 92-501 Safety against fire - Building materials - Reaction to fire tests - Used for rigid material or flexible materials thicker than 5 mm
• NF P 92-503 Safety against fire - Building materials - Reaction to fire tests - Electric burner test used for flexible materials
• NF P 92-504 fire safety - Building materials - Reaction to fire tests - Flame resistance test and flame propagation speed
• NF P 92-505 Safety against fire - Building materials - Reaction to fire tests - Test used for thermal melting materials - Drip test

Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, within the scope of NF P92-507 standard, fire safety, building interior equipment materials, tests for classification according to fire reactions. also provides services.
