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..

Maximum explosion pressure earlimart topix forumWebFlammability limit refers to the upper or lower limits of the gaseous or vaporized fuel or combustible material at a fixed temperature and pressure that can lead to flame propagation, detonation or an explosion. Fuel or combustible concentrations outside the both limits are considered to be non-flammable. Safeopedia Explains Flammability Limit css image-rendering

"WebPropane Limits of Flammability - The lower and upper limits of flammability are the percentages of propane that must be present in an propane/air mixture. This means that between 2.15 and 9.6% of the total propane/air mixture must be propane in order for it to be combustible. If the mixture is 2% propane and 98% air, there will not be combustion.
