The flash point of a material is the "lowest liquid temperature at which, under certain standardized conditions, a liquid gives off vapours in a quantity such as to be capable of forming an ignitable vapour/air mixture". (EN 60079-10-1)
6 days ago · flash point, the lowest temperature at which a liquid (usually a petroleum product) will form a vapour in the air near its surface that will “flash,” or briefly ignite, on exposure to an open flame. The flash point is a general indication of the flammability or combustibility of a liquid.
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.
The flash point of a product is the lowest temperature at which it emits sufficient vapors to form an ignitable mixture with air near its surface. In simpler terms, it is the temperature at which the product can catch fire if exposed to an open flame or spark.
Flash point refers to the lowest temperature at which a substance emits enough vapor to form an ignitable mixture with air, but does not sustain combustion. Unlike autoignition temperature, flash point requires an external ignition source to sustain the flame.
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. At the flash point, the vapor may cease to burn when the ignition source is removed.
The flash point of a substance is a measure of its flammability. It is the lowest temperature at which a liquid or solid can vaporize to form an ignitable mixture in air near the surface of the liquid.
Flash Point. The Flash Point of a liquid is the minimum temperature at which a liquid gives off vapor within a test vessel in sufficient concentration to form an ignitable mixture with air near the surface of the liquid.
noun. AlsoPhysical Chemistry.
The lowest temperature at which the vapor of a flammable liquid will ignite in air. The flash point is generally lower than the temperature needed for the liquid itself to ignite.
