NF P92-504 Building Materials Fire Test, Standard Test for Flame Test Propagation Rate

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of NF P92-504 testing. Standard NF P92-504, a French standard (NF, Norme Française), describes a test method for determining the flame propagation rate for building materials not intended to be bonded to a rigid substrate.

These tests are carried out to determine the horizontal flame spread rate of the materials. This test method is also valid for other rapidly melting building materials and building materials that do not burn in the tests or fail to obtain M1, M2 and M3 material classes.

During the tests for the NF P92-501 standard and the NF P92-503 standard, if the material does not burn or if the burning time is 5 seconds or less, it is necessary to test according to the fire resistance test classification. In the fire resistance test process, the flame lasts no more than two seconds and the melted combustion drops do not fall.

Other standards similar to the NF P92-504 standard are:

  • NF P92-501 Reaction to fire tests;
  • NF P92-503 Electric burner test used for flexible materials;
  • NF P92-505 Test used for thermal melting materials - Drop test;
  • NF P92-507 Classification according to reaction to fire.

Briefly, the NF P92-505 test is used to determine whether the produced materials will be fired from the droplet. If the fire reaction test in the droplet produced from other non-combustible materials does not detect that the flame propagation speed is reduced, the drip test must be performed.
