NF P92-505 Building Materials Fire Test, Drip Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of NF P92-505 testing. One of the building materials fire tests is the NF P92-505 standard, which is also a French standard (NF, Norme Française).

This standard provides a method for the electric radiator drip test used in melting materials. If melt drops appear in NF P92-501 and NF P92-503 tests, whether or not combustion occurs, the NF P92-505 test must be performed.

Evaluation is made according to the M classification system as follows:

• M1 = non-flammable (calorific value 2508 kJ / kg or less);
• M2 = Low flammability;
• M2 = Low flammability (2.5 < q < 15);
• M3 = Moderate flammability (15 < q < 50);
• M4 = High flammability (q > 50).

In this classification, the contribution of the material to the fire is mainly based on the ignition time. In general, the NF P92-504 and 505 test methods are complementary tests that should be performed when certain unusual conditions (such as falling burning droplets) are observed. In this case, the results from these two tests are used to determine the M grade.

Other standards similar to the NF P92-505 standard are:

• NF P92-501 Reaction to fire tests;
• NF P92-503 Electric burner test used for flexible materials;
• NF P92-504 Flame persistence test and flame propagation speed;
• NF P92-507 Classification according to reaction to fire.

Within the scope of fireproof tests, EUROLAB also provides NF P92-505 Building materials fire test - Drip test services. Thanks to these services, businesses receive more efficient, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
