ActivePetroleum products--Calculation of viscosity index
石油产品粘度指数计算法
Application Summary AI generated
This standard specifies the calculation method for determining the viscosity index of petroleum products based on their kinematic viscosities at 40°C and 100°C. It is applied in the petroleum industry for quality control and classification of lubricating oils, hydraulic fluids, and similar products, enabling assessment of viscosity-temperature behavior. The standard is used by refineries, testing laboratories, and procurement professionals to ensure product consistency and performance across varying operating temperatures.
