  2. Flash point - Wikipedia

    en.wikipedia.org/wiki/Flash_point

    The TAG flash point tester adheres to ASTM D56 and has no stirrer, while the Abel flash point testers adheres to IP 170 and ISO 13736 and has a stirring motor so the sample is stirred during testing. The flash point is an empirical measurement rather than a fundamental physical parameter.

  3. Cleveland open-cup method - Wikipedia

    en.wikipedia.org/wiki/Cleveland_open-cup_method

    The lowest temperature at which a small test flame passing over the surface of the liquid causes the vapor to ignite is considered the chemical's flash point. This apparatus may also be used to determine the chemical's fire point which is considered to have been reached when the application of the test flame produces at least five continuous ...

  4. Flashover - Wikipedia

    en.wikipedia.org/wiki/Flashover

    Flashover occurs when the majority of the exposed surfaces in a space are heated to their autoignition temperature and emit flammable gases (see also flash point). Flashover normally occurs at 500 °C (932 °F) or 590 °C (1,100 °F) for ordinary combustibles and an incident heat flux at floor level of 20 kilowatts per square metre (2.5 hp/sq ft).

  5. Flame detector - Wikipedia

    en.wikipedia.org/wiki/Flame_detector

    A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection.Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.

  6. Fire point - Wikipedia

    en.wikipedia.org/wiki/Fire_point

    The fire point, or combustion point, of a fuel is the lowest temperature at which the liquid fuel will continue to burn for at least five seconds after ignition by an open flame of standard dimension. [1] At the flash point, a lower temperature, a substance will ignite briefly, but vapour might not be produced at a rate to sustain the fire ...

  7. Autoignition temperature - Wikipedia

    en.wikipedia.org/wiki/Autoignition_temperature

    The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. [1]

  8. Pensky–Martens closed-cup test - Wikipedia

    en.wikipedia.org/wiki/Pensky–Martens_closed-cup...

    This allows the development of an equilibrium between the liquid and the air volume. The ignition source is directed into the cup at regular intervals with simultaneous interruption of stirring. The test concludes upon observation of a flash that spreads throughout the inside of the cup. The corresponding temperature is the liquid's flash point.

  9. Fire accelerant - Wikipedia

    en.wikipedia.org/wiki/Fire_accelerant

    It boasts a flash point of -45 degrees F (-43 degrees C) and an ignition temperature ranging from 536 degrees F (280 degrees C) for 56-60 octane grade. With explosive limits from 1.4% to 7.6%, its vapor density ranges from 3.0 to 4.0, with a specific gravity of 0.8.
