NOTES:

1. Kinematic Viscosity and Viscosity Index are now standardized on tests made at 40C and 100C.

2. Kinematic viscosity at 100F and 210F can be computed from measurements made at 40C and 100C if these are required.

3. Saybolt Universal Viscosity data can also be computed from the same Kinematic viscosity measurements when required.
