Flash point, английский
- Температура вспышки
- The temperature at which a liquid produces enough vapor to form an inflammable mixture with air.
- The minimum temperature of a combustible material at which there is sufficient vaporization to produce a combustible mixture with air if ignited by a flame. flash set, grab set, quick set the rapid development of rigidity in a freshly mixed portland cement paste, mortar, or concrete, usually with the generation of considerable heat; this rigidity cannot be dispelled, nor the plasticity regained by further mixing, without the addition of water.
- The flash point is the lowest temperature at which a substance vaporizes into a gas, which can be ignited with the introduction of an external source of fire.
- Lowest temperature at which vapor from a sample of a petroleum product or other combustible fluid will “flash” in the presence of an ignition source. the flash can be seen in the form of a small spark over the liquid.
- The lowest temperature at which vapours rising from a sample will ignite momentarily on application of a flame under specified conditions.
- The lowest temperature at which a substance will decompose to a flammable gaseous mixture. the temperature at which the vapor air mixture first ignites is the flash point. this temperature can be determined by raising the temperature of the liquid in accordance with the pre-determined schedule, and periodically introducing a flame or other ignition means immediately above the surface.
- Lowest temperature at which vapors above a volatile, combustible substance ignite in air when exposed to an ignition source.
- Lowest temperature at which a substance will form an ignitable mixture in air. the value varies with circumstances. glossary f-g 499
