The Speed of Spread of Flame Test Device, in accordance with NF P 92-504, is used to determine the reaction to fire behavior and speed of spread of flame for flexible and rigid building materials when exposed to a defined flame. The NF P 92-504 test is applied to classify the material from M0 to M4 of the French building materials. Speed of Spread of Flame Test Device consists of • Compactly designed, all elements are installed on the black painted base. • U-shape specimen holder, stainless steel made. • Standard burner, provides a 20mm height flame. • The burner can be turned to 45 degrees. • A needle valve controls the propane flow. • A motor controls the horizontal movement. • Provides flame gauge and sample template. The French M Classification for Building Materials (NF P 92-507) The “Reaction to Fire” tests classify the material into 5 categories from M0 to M4. The specific standard that is applicable depends on the intended use and defines test methods for all materials. • M0 - Non-flammable (Calorific Value ≤ 2.5 MJ/kg) • M1 - Non-flammable (Calorific Value ＞ 2.5 MJ/kg) • M2 - Low flammability • M3 - Moderately flammable • M4 - High flammability
