ActivePetroleum products--Determination of kinematic viscosity and calculation of dynamic viscosity
石油产品运动粘度测定法和动力粘度计算法
Application Summary AI generated
This standard specifies a method for determining the kinematic viscosity of liquid petroleum products using a capillary viscometer at a controlled temperature, and provides the formula for calculating dynamic viscosity from the measured value. It is applied in the petroleum industry for quality control of lubricating oils, fuel oils, and other liquid petroleum products, particularly in testing laboratories and refineries. The standard is also used in procurement and specification compliance to ensure products meet required viscosity grades for engine and industrial applications.
