the lowest temperature at which the vapors given off by a volatile liquid exposed to air will burst into flame when approached by a flame. Also called flashing point.
Temperature at which a material begins to vaporize.
The temperature at which a liquid will give off enough flammable vapor to ignite. The lower the flash point, the more dangerous the product. HAZARD RATINGS: Material ratings of one to four which indicate the severity of hazard with respect to health, flammability, and reactivity.
The lowest temperature at which a liquid will give off vapors in sufficient concentrations to ignite.
This is the minimum temperature at which the vapor above a liquid fuel will first support a combustion transient or "flash". The flash point is measured by a standardized test using a small quantity (50 cc) of liquid that is slowly heated (about 1 deg C/minute) until a flash is observed when an open flame is dipped down into a covered vapor space. The legal description of flammable is used for all liquids with a flash point less than 100 deg C, and the term combustible is used for liquids with a flash point in excess of 100 deg C.
The minimum temperature at which a commodity produces enough fumes to form a combustible mixture with air.
The temperature at which a combustible liquid gives off just enough vapor to produce a vapor/air mixture that will ignite when a flame is applied. The flash point is measured in a standardized apparatus using standard test methods, such as ASTM D93 or ISO 2719.
The flash point is the lowest temperature at which a liquid can form an ignitable mixture in air near the surface of the liquid. See what is a Material Safety Data Sheet

(noun) 1 : the lowest temperature at which vapors above a volatile combustible substance ignite in air when exposed to flame 2 : a point at which someone or something bursts suddenly into action or being (Date: 1878) (Merriam-Webster's Unabridged at www.m-w.com)
The temperature at which the vapors produced from a fluid will ignite (flash off) with the presence of an ignition source (the fluid will not burn at this point). The flash point is important from the viewpoint of safety; however it is quite common for heat transfer systems to be operated at temperatures above the flash point of the fluid.
The lowest temperature at which a substance gives off enough vapors to form a flammable mixture.
Is defined as the lowest temperature at which flammable vapor is given off a liquid in a test vessel in sufficient concentration to be ignited in air when exposed momentarily to a source of ignition. This does not mean the temperature at which a liquid ignites spontaneously.
the lowest temperature at which a liquid can form an ignitable mixture in air near the surface of the liquid. The lower the flash point, the easier it is to ignite the material; for example, gasoline has a flash point of -40oC (-40oF) and is more flammable than ethylene glycol (antifreeze) which has a flash point of 111oC (232oF). The U.S. Department of Transportation (DOT) requires that all substances transported have a flash point determined and that any materials with flash points lower than 60oC (140oF) be handled with extra caution. A closely related and less common term is fire point, the temperature at which the flame becomes self-sustained so as to continue burning the liquid (at the flash point, the flame does not need to be sustained). OSHA's Standard 1910.106 mandates flash point determinations using one of two standardized testing methods specified by the American Society for Testing and Materials (ASTM). Other agencies and sections of the U.S. Code may specify alternative methods, but the general concept is similar in each case [N20].

of a chemical is the lowest temperature at which a flame will propagate through the vapour of a combustible material to the liquid surface. It is determined by the vapour pressure of the liquid, since only when a sufficiently high vapour concentration is reached, can it support combustion. It should be noted that the source of ignition need not be an open flame, but could equally be, for example, the surface of a hot plate, or a steam pipe.
