1. Scope

1.1 This practice specifies the procedures for calculating the viscosity index of petroleum products, such as lubricating oils, and related materials from their kinematic viscosities at 40 and 100°C.

1.1.1 Procedure A--For petroleum products of viscosity index up to and including 100.

1.1.2 Procedure B--For petroleum products of which the viscosity index is 100 or greater.

1.2 Table 1 given in this practice applies to petroleum products with kinematic viscosities between 2 and 70 mm2/s (cSt) at 100°C. Equations are provided for calculating viscosity index for petroleum products having kinematic viscosities above 70 mm2/s (cSt) at 100°C.

1.3 The kinematic viscosity values are determined with reference to a value of 1.0038 mm2/s (cSt) at 20.00°C for distilled water. The determination of the kinematic viscosity of a petroleum product shall be carried out in accordance with Test Methods D 445, IP 71, ISO 3104, or ISO 2909.

1.4 The values stated in SI units are to be regarded as the standard.
