GB/T 1995-1998 "Petroleum Product Viscosity Index Calculation Method" stipulates the calculation method of petroleum product viscosity index. The standard is based on the kinematic viscosity data of petroleum products at different temperatures, and gives detailed calculation principles, formulas and steps. The viscosity index is calculated to measure the viscosity of petroleum products with temperature changes. It provides a scientific calculation basis for the performance evaluation, quality control and rational selection of petroleum products.
