Füstpontot

Füstpontot is a Hungarian term that translates to "flash point" in English, referring to the lowest temperature at which a volatile liquid can vaporize to form an ignitable mixture in air. This concept is crucial in understanding the flammability of substances and is a key safety parameter in handling and storing various chemicals, fuels, and solvents.

The flash point is determined through specific standardized tests. A sample of the liquid is heated in a controlled environment, and a small flame is passed over its surface at regular intervals. The flash point is the lowest temperature at which the vapor above the liquid ignites with a brief flash when exposed to the ignition source. It's important to distinguish the flash point from the autoignition temperature, which is the temperature at which a substance will ignite spontaneously without an external ignition source.

Understanding the füstpontot of a substance is vital for risk assessment. Liquids with lower flash points are more flammable and require stricter precautions to prevent fires and explosions. This information is typically found on safety data sheets (SDS) and is used in regulations concerning transportation, storage, and handling of hazardous materials. For example, gasoline has a significantly lower füstpontot than diesel fuel, dictating different storage and handling requirements.
