NF P 92-503 Fire Safety - Building Materials - Response to Fire Tests - Electric Burner Test Used for Flexible Materials

The NF P92-503 standard, which is a French standard, describes the electric burner test method used for flexible construction materials, flexible filter materials and other similar construction materials.

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)

Three factors are important in testing under this standard: burning time, dripping property and destruction length of the samples tested.

Flexible material flammability class testing machine is used in the test method described in the NF P92-503 standard. This testing machine is designed to determine flammability, fusion and inert class according to that standard. In this way, the flammability level of the material is measured and the reaction of flexible material curtains, tight decorative fabrics or wall coverings to fire is determined.

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 92-504 Safety against fire - 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
  • NF P 92-507 Fire safety - Building - Interior equipment materials - Classification by reaction to fire
