Petroleum products — Calculation of viscosity index from kinematic viscosity
OVERVIEW
Specifies two procedures at 40 °C and 100 °C. Procedure A is applicable to viscosity indices up to and including 100, procedure B to viscosity indices 100 and greater. The table given applies to kinematic viscosities between 2 and 70 mm /s at 100 C. The values are determined with reference to a value of 1,003 8 mm /s at 20,00 °C for distilled water.
