Flammability limits in air
WebA flammable material is something that can burn (i.e., sustain a flame) in air under certain conditions.A flammable material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.. The degree of flammability in air …
