POUR POINT
The temperature when the oil actually congeals and no longer flows is called as pour point. Basically it is the lowest temperature at which the oil stops flowing or cannot be poured when cooled and tested under prescribed condition of test.
The pour point of a oil is the lowest temperature at which an oil is observed to flow by gravity in a specified lab test. Specifically, the pour point is 3 degrees C (5 degrees F) above the temperature at which the oil shows no movement when a lab sample container is held horizontally for 5 seconds.
The pour point of a petroleum product is an index of the lowest temperature of its utility for certain applications. Flow characteristics, like pour point, can be critical for the correct operation of lubricating oil systems, fuel systems, and pipeline operations.
Pour point should not be confused with Cloud point or Freezing point.
Cloud point should not be confused with Pour point or Freezing point.
