In China, the indicators used for this purpose are the freezing point and the cold filter plugging point.

The indicators used in our country to evaluate the low-temperature flowability of diesel are the freezing point and the cloud point. Freezing point is also an important quality indicator for diesel. In winter, or when the air temperature drops to a certain level, the wax crystals that form in diesel cause it to lose its fluidity, posing difficulties in its use, storage, and transportation. For crude oils with high wax content, dewaxing is often required during the production process in order to obtain diesel whose freezing point meets the specified requirements; generally, the lower the boiling range of the diesel, the lower its freezing point.

The cold filter point is an indicator of diesel’s flowability at low temperatures.
The indicator for evaluating the low-temperature flowability of diesel is the freezing point. Put simply, they are diesel grades such as -10#, 0#, etc. @chunhui1009 @sdshihua @slll611 @zls1457 @Guan Gongyu @Black Toothpaste @Black Toothpaste

The main indicators for assessing the low-temperature flowability of diesel are its pour point, cloud point, and cold filter plugging point.
