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

  1. Flash point measures the tendency of the sample to form a flammable mixture with air under controlled laboratory conditions.
  2. It is only one of the numbers of properties that must be considered in assessing the overall flammability hazard of the material.
  3. Flash point is used in shipping and safety regulations to define flammable and combustible materials.
  4. One should consult the particular regulations involved for precise definitions of these classes.
  5. Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively non-volatile or non-flammable products.
  6. Fire point of Petroleum products measures the characteristics of the sample to support combustion.
