GB/T 265-1988
Petroleum products--Determination of kinematic viscosity and calculation of dynamic viscosity

GB/T 265-1988 specifies the method for determining the kinematic viscosity of transparent and opaque petroleum products (including crude oil) using capillary viscometers, and provides the formula for calculating dynamic viscosity based on the measured kinematic viscosity and density. It is a fundamental and widely used standard for viscosity measurement in the petrochemical industry.
