- 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 100176C.
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 mm /s (cSt) at 100176C. Equations are provided for calculating viscosity index for petroleum products having kinematic viscosities above 70 mm /s (cSt) at 100176C.
1.3 The kinematic viscosity values are determined with reference to a value of 1.0038 mm /s (cSt) at 20.00176C for distilled water. The determination of the kinematic viscosity of a petroleum product shall be carried out in accordance with Test Methods D445, IP 71, ISO 3104, or ISO 2909.
1.4 The values stated in SI units are to be regarded as the standard.
