ASTM D2270-93-Reapproved1998<\/h3>\n

Historical Standard: Standard Practice for Calculating Viscosity Index From Kinematic Viscosity at 40 and 100\u00b0C<\/h4>\n
\n

ASTM D2270<\/h4>\n

Scope<\/strong><\/p>\n

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\u00b0C.<\/p>\n

1.1.1 Procedure A -For petroleum products of viscosity index up to and including 100.<\/p>\n

1.1.2 Procedure B -For petroleum products of which the viscosity index is 100 or greater.<\/p>\n

1.2 Table 1 given in this practice applies to petroleum products with kinematic viscosities between 2 and 70 mm \/s (cSt) at 100\u00b0C. Equations are provided for calculating viscosity index for petroleum products having kinematic viscosities above 70 mm \/s (cSt) at 100\u00b0C.<\/p>\n

1.3 The kinematic viscosity values are determined with reference to a value of 1.0038 mm \/s (cSt) at 20.00\u00b0C 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.<\/p>\n

1.4 The values stated in SI units are to be regarded as the standard.<\/p>\n
