Fältkoder IN KNFLAMPKT | UT WIFLAMPKT | API flashPoint
The flash point is the temperature at which a liquid emits vapors in a concentration sufficient for ignition.
Information and Description
Substances with a low flash point are more flammable than those with a high flash point. This information is mandatory if the product is subject to regulatory requirements.
The flash point is also used as a parameter to determine the fire classification of an article. This classification can then serve as the basis for calculations ensuring that the permitted quantity of flammable material, for example in storage or sales areas, is not exceeded.
Classification of Flammable Liquids
Flammable liquids are divided into four classes depending on their flash point.
|
Class |
Flash Point |
Example |
|---|---|---|
|
1 |
<21°C |
Petrol, acetone, methylated spirits |
|
2a |
21°-30°C |
Xylene |
|
2b |
30°-55°C |
Kerosene, lighter fluid, turpentine, oil-based paint |
|
3 |
55°-100°C |
Diesel, heating oil |
It is important to note that a flammable liquid can ignite below its flash point, for example, if it is sprayed into mist form from a leaking seal or hydraulic hose.
A wick, cloth, or piece of waste material soaked with the liquid can also change the conditions, allowing ignition below the flash point.
