Distinguish between flash point and fire point

The differences between flash point and fire points are as follows-

Flashpoint Fire point
Flashpoint of given lubricants is defined as the lowest temperature at which the lubricant under test gives off sufficient vapours to produced a momentary spark when a standard flame is brought near it. Fire point of lubricants is defined as the lowest temperature at which the vapours temperature at which the lubricants under test catch fire for at least 5 seconds when a standard flame is brought near it.
It has a lower value than the corresponding fire point of the same oil. Fire point is 150C to 300C higher than the flash point of the same oil.
Comparatively less time is required to determine the flash point. Comparatively more time is required to determine fire point.
Usually, the flash point of oil is determined. Rarely, a fire point of oil is determined.
