Floc point, also known as Freon floc point, is used to measure the performance and consistency of refrigeration oils. In order for the refrigeration system to function properly, the oil used should be compatible. Wax can separate when an oil solution is cooled with Freon. Once the wax is separated it is called flocculation and that is the reason it is called floc point.
It varies with the oils viscosity.
The pour point test determines the lowest temperature at which a substance will flow or be able to flow. This is important for understanding how a substance will behave in cold temperatures, such as in transportation and storage of petroleum products. Knowing the pour point helps prevent issues such as pipeline blockages or difficulties in starting engines in cold climates.
Yes, viscous oil can freeze, but the freezing point will depend on the specific type of oil and its composition. Generally, oils with low viscosity and high pour points are more likely to freeze at lower temperatures compared to oils with higher viscosity and lower pour points.
The definition of pour point is the lowest temperature at which a liquid begins to turn into a solid, so much so that it can no longer flow.
The "Pour Point" of engine oil is about -44ºF.
At a defined temperature a liquid become semisolid and doesn't easily flow: this is the pour point. This is important to establish the temperature range in which this material can be used.
The pour point is the lowest temperature at which the fuel will flow. Pour point depressant will allow fuel to be used at a lower temperature without problems. Fuel oil must be pumped before it is used and if the viscosity is too high the oil will not flow easily. Pour point depressant might also allow fuel oil to be stored at a lower temperature thus saving some energy that would normally be used to keep it above its pour point. The chemical names of fuel additives are often proprietary and kept a secret, however see the related links for a discussion of pour point depressants.
Pull the thingy out of the valve cover and insert funnel. Pour the oils into the funnels.
At a defined temperature a lubricant become semisolid and doesn't easily flow: this is the pour point. This is important to establish the temperature range in which this lubricant can be used.
Flash point is the temperature at which a combustible material begins to give off enough vapors that it can be ignited with a spark. Pour point is the temperature at which a viscous fluid will flow easily, primarily used to indicate the ability to pump the fluid.
Certain oils, such as coconut oil and olive oil, can solidify at low temperatures but do not actually freeze. However, oils with low pour points, like canola oil or sunflower oil, remain liquid even at typical winter temperatures. These oils have a lower saturation level, which prevents them from solidifying in the cold. For extreme cold, mineral oils or specific synthetic oils are designed to stay liquid in frigid conditions.
