The temperature at which a liquid will yield enough flamable vapour to ignite There are various recognized industrial testing methods; therefore the method used must be stated
means the minimum temperature at which a liquid within a container gives off vapour in sufficient concentration to form an ignitable mixture with air near the surface of the liquid (Ontario Fire Code 1996)
The Flash Point is the lowest temperature at which a liquid or a solid gives off enough vapor to form flammable air-vapor mixture near its surface The lower the flash point, the greater the fire hazard The flash point is an approximate value and should not be taken as a sharp dividing line between safe and hazardous conditions The flash point is determined by a variety of test methods which give different results Two of these methods are abbreviated as OC (open cup) and CC (closed cup)
Temperature at which a liquid will give off enough flammable vapor to ignite There are several flash point test methods, and flash points may vary for the same material depending on the method used, so the test method is indicated when the flash point is given
The temperature to which a combustible liquid must be heated to give off sufficient vapor to form momentarily a flammable mixture with air when a small flame is applied under specified conditions (ASTM Designation D 92 )
The temperature at which a liquid or volatile solid gives off vapor sufficient to form an ignitable mixture near the surface of the liquid or within the test vessel
lowest temperature at which a substance produces vapors that ignite immediately when subjected to a flame (Chemistry); critical point that causes change; situation that will likely become violent
the lowest temperature at which a flammable liquid will produce a combustible vapor that will burn in the presence of a flame, under certain prescribed conditions of test
The lowest temperature at which a liquid gives off enough vapor to form an ignitable mixture and burn when a source of ignition (sparks, open flames, etc ) is present Two tests are used to determine the flash point: open cup and closed cup The test method is indicated on the MSDS after the flash point
of a chemical - 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
