Introduction
NF P 92-504 for the determination of horizontal flame spread rate of materials. This method also applies in other rapidly melting and testing without burning, or not achieve M1 ~ M3 material.
This speed of spread of flame test is intended to test a sample of a material under certain conditions to a heat source consisting of a gas igniter, and may trigger: sample fire and flame persistence test and flame spread and spread. The speed test is in accordance with the fire reaction performance test of French building materials and high-iron non-metallic materials.
Standard
NFP 92-504 speed of spread of flame test.
Features
1. The flame spread tester is applicable to French building materials and high-speed rail test standard NFP 92-504;
2. Using a standard burner, the sample is subjected to flame impact, and then the flame spread performance of the sample is observed;
3. U-shaped specimen holders with soft and hard materials at the same time;
4. The burner movement adopts a programmable controller, and the test time and the number of ignitions can be automatically controlled.
