WebThis test is conducted to determine the lower and upper concentration limits of flammability of chemicals having sufficient vapor pressure to form flammable ... WebFlammable (Explosive) Limits. The percent levels, volume by volume, of a flammable vapor or gas mixed in air between which propagation of a flame or an explosion will occur upon the presence of ignition. The leanest mixture at which this will occur is called the lower flammable limit.
