| Ignition temperature | Aerospace | Surface temperature of a solid-propellant grain at the moment combustion begins; the temperature depends on the extent of pyrolysis, on heating rate, and on pressure, especially at low pressures and high flux levels. (references) | |
| Ignition temperature | Mining | 1: The lowest temperature of a substance at which sustained combustion can be initiated. Also called kindling point. (references) | |
| 2: A. The ignition temperature of a substance is the temperature at which that substance starts to burn. The temperature of ignition varies greatly with different substances. All solid fuels must be heated to their ignition temperature before they will burn continuously by the process known as combustion b. The temperature required to effect ignition of a combustible-oxidant system at a specified pressure; in general, the minimum temperature is implied. (references) | |||
| Ignition temperature | Physics | For given values of density and energy confinement, the temperature at which ignition occurs. (see ignition). (references) | |
| Ignition temperature | Security | The minimum temperature to which a material must be raised before it will burn. The ignition temperature is higher than the flashpoint. (references) | |
| Ignition temperature | Transportation | The minimum temperature required to ignite gas or vapor without a spark or flame being present. See FLAMMABLE (EXPLOSIVE) RANGE. (references) | |
