Definition of flash and fire point of petroleum products are described below:
Flash point of Petroleum products
It may be defined as:
Flash point of Petroleum products is the lowest temperature corrected to a barometric pressure of 101.3 kpa ( 760 mm Hg), at which application of a test flame causes the vapor of a specimen to ignite under specified conditions of test.
Fire point of Petroleum products
It may be defined as
Fire point of Petroleum products is the lowest temperature at which a specimen will sustain burning for 5 seconds.
Significance and use
- Flash point measures the tendency of the sample to form a flammable mixture with air under controlled laboratory conditions.
- It is only one of the numbers of properties that must be considered in assessing the overall flammability hazard of the material.
- Flash point is used in shipping and safety regulations to define flammable and combustible materials.
- One should consult the particular regulations involved for precise definitions of these classes.
- Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively non-volatile or non-flammable products.
- Fire point of Petroleum products measures the characteristics of the sample to support combustion.
