The degree of difficulty required to cause the combustion of a chemical is quantified through fire testing. Usually materials are rated as highly flammable, flammable and non-flammable. You can often find it in the section 9 of a safety data sheet (SDS).

WebThis test establishes the specimen’s flame spread index and smoke developed value. The flame spread index measures the flame growth across the surface of the specimen by recording both the time at which the test specimen ignites, and the time at which the flame’s maximum distance is reached. WebFor the awning to meet the required fire hazard properties, the sarking-type material must have a maximum Flammability Index of 5 as specified in Table 4 of Specification C1.10. The other materials in the awning must have a maximum Spread-of-Flame Index of 9 and, if the Spread-of-Flame Index is greater than 5, it must also have a maximum Smoke ...
