Petroleum products – Calculation of viscosity index from kinematic viscosity

BH GSO ISO 2909:2024 Files

BH GSO ISO 2909:2024 Scope

This International Standard describes two procedures for calculating the viscosity index (VI) of petroleum products and related materials, such as lubricating oils, from their kinematic viscosities at 40 °C and 100 °C. Procedure A is applicable to petroleum products of viscosity index up to and including 100. Procedure B is applicable to petroleum products of viscosity index 100 or greater.
