SY/T 0522-2008 《Determination of wax evolution point of crude oil rotational viscometer method》 Related products

The standard "SY/T 0522-2008 Rotational viscometer method for determining the wax evolution point of crude oil" provides a method for determining the wax evolution point of crude oil by rotational viscometer. The method determines the wax evolution point of crude oil by analyzing the viscosity change of crude oil under low temperature conditions, that is, the temperature at which the crude oil begins to precipitate solid wax during the chilling down process. The standard specifies the test conditions, operation procedures and data processing in detail, aiming to provide a scientific basis for the freezing and transportation of crude oil.
