NFP 92-504 Flame Spread Tester
With the continuous development of science and technology, rail vehicles are entering the era of increasing speed. Non-metallic materials for subway, bullet train, train and other rail vehicles are used in many ways, and the fire prevention performance of non-metallic materials plays a key role in the fire prevention and control of high-speed trains. Therefore, adopting materials that meet the standard requirements of fire prevention, flame retardant, low smoke and low toxicity can minimize the risk of fire.
Flame spread tester is suitable for French building materials and high-speed rail test standard NFP 92-504. It is a kind of test for sample fire and flame persistence, as well as flame spread and spread speed, which meets the fire reaction performance test of French building materials and high-speed rail nonmetallic materials.
Use the standard burner of the instrument to conduct flame impact on the sample to better observe the flame spreading performance of the sample. Equipped with soft and hard U-shaped sample clamps, the quality is guaranteed, and users can choose according to their needs. The programmable controller is used to realize the automation of operation process, and the test time and ignition times can be automatically controlled, with high reliability and strong anti-interference ability.
