The flash point of a chemical substance is the lowest temperature where enough fluid can evaporate to form a combustible concentration of gas. The flash point is an indication of how easy a chemical may burn. Materials with higher flash points are less flammable or hazardous than chemicals with lower flash points.
Jan 13, 2016 · Flash point is the lowest temperature at which a chemical can vaporize to form an ignitable mixture in air. A lower flash point indicates higher flammability. Measuring a flash point (open-cup or close-cup) requires an ignition source.
The meaning of FLASH POINT is the lowest temperature at which vapors above a volatile combustible substance ignite in air when exposed to flame. How to use flash point in a sentence.
“Flash point” is the minimum temperature at which a liquid gives off vapor within a test vessel in sufficient concentration to form an ignitable mixture with the air near the surface of the liquid. The lower the flash point, the easier it is to ignite a liquid solvent.
By definition, the flash point is the lowest temperature at which the vapor formed above a pool of liquid can be ignited in air at atmospheric pressure. At the flash point, the flame will stop as soon as the ignition source is removed.
Flash point definition: the lowest temperature at which a liquid in a specified apparatus will give off sufficient vapor to ignite momentarily on application of a flame.. See examples of FLASH POINT used in a sentence.
