Webtest method for assessing the surface burning characteristics of building products. The purpose of this test is to observe the flame spread along a sample in order to determine the relative burning behavior of its material. Through the E84 test, both Flame Spread Index (FSI) and Smoke Developed Index (SDI) are reported for a given sample. Web5 Aug 2024 · The resulting number is the flame spread index. Flame spread ratings range from an index of 0-200, with Class A being the best with an index of 0-25, Class B with an index of 26-75, and Class C with an index of 76-200. Lower classes (indices higher than 25) indicate that flames spread more quickly and covered a greater distance than compared …
