The flash point of a volatile material is the lowest temperature at which its vapors ignite if given an ignition source. The flash point is sometimes confused with the autoignition temperature , the temperature that causes spontaneous ignition. The fire point is the lowest temperature at which the vapors keep burning after the ignition source is removed.
The flash point of a volatile material is the lowest temperature at which it can vaporize to form an ignitable mixture in air. Measuring a flash point requires an ignition source. At the flash point, the vapor may cease to burn when the source of ignition is removed. The fire point of a fuel is the temperature at which the vapour produced by that given fuel will continue to burn for at least 5 seconds after ignition by an open flame. At the flash point, a lower temperature, a substance will ignite briefly, but vapor might not be produced at a rate to sustain the fire. However, vapors cease to burn if the source of ignition is removed.
This test is done to determine the flash point and the fire point of asphaltic bitumen and fluxed native asphalt, cutback bitumen and blown type bitumen as per IS: — The principle behind this test is given below :. Flash Point — The flash point of a material is the lowest temperature at which the application of test flame causes the vapours from the material to momentarily catch fire in the form of a flash under specified conditions of the test. Fire Point — The fire point is the lowest temperature at which the application of test flame causes the material to ignite and burn at least for 5 seconds under specified conditions of the test. The sample should be just sufficient to fill the cup upto the mark given on it. Stir it thoroughly to remove air bubbles and water.

Где ей еще быть в субботний вечер. Проклиная судьбу, он вылез из автобуса. К клубу вела узкая аллея. Как только он оказался там, его сразу же увлек за собой поток молодых людей.
Это не имеет никакого отношения к Попрыгунчику, - резко парировала. Вот это чистая правда, - подумал Джабба. - Послушай, Мидж, к Стратмору я не отношусь ни плохо ни хорошо. Ну, понимаешь, он криптограф. Они все, как один, - эгоцентристы и маньяки.
Но он прошел Сквозь строй. - Если эта система его не перехватила, то откуда вы знаете, что вирус существует. Чатрукьян вдруг обрел прежнюю уверенность. - Цепная мутация, сэр.
Flash point: the lowest temperature at which vapours above a liquid will ignite when exposed to an ignition source.Tfoster 22.05.2021 at 22:53
Introduction. The flash and fire points of a liquid fuel specimen are the indicators of its flammability. In general, flash point is the lowest temperature of the test.Nicholas R. 24.05.2021 at 13:54
The flash point is defined as the lowest temperature at which a flammable liquid gives off sufficient vapor to form an ignitable mixture with air near its surface or.
