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)
Aug 8, 2024 · 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 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” 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.
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 is the lowest temperature at atmospheric pressure (760 mm Hg, 101.3 kPa) at which application of a test flame will cause the vapor of a sample to ignite under specified test conditions.
Flash point is used to determine whether contamination of a product has occurred. Changes in flash point indicate that a sample may have been contaminated or adulterated, for example, petroleum spirit in engine oil will lower the flash point.
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 temperature where the combustible material can ignite by an external ignition source. It is the lowest temperature at which vapors of the material will ignite, when the flammability and an ignition source are given.
What is Flash Point. 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.
