Süütepunkti

Süütepunkti, often translated as ignition point or spark point, refers to the temperature at which a combustible material will ignite and burn when exposed to a flame or spark. This is a critical property in understanding fire safety and the behavior of various substances. It is distinct from flash point, which is the lowest temperature at which a liquid can form an ignitable vapor mixture in air. At the süütepunkti, the vapors are capable of sustaining combustion even after the ignition source is removed.

The süütepunkti is influenced by several factors, including the chemical composition of the material, its physical state (solid, liquid, or gas), and the presence of oxygen. For solids, it often refers to the temperature at which smoldering begins or self-sustaining combustion occurs. For gases and vapors, it is the minimum concentration in air that will ignite. This property is essential for determining safe handling, storage, and transportation procedures for flammable and combustible materials. Different organizations and standards may use slightly varying definitions and testing methods for determining süütepunkti, but the core concept remains the temperature at which self-sustaining combustion begins.
