ASTM D2270-04<\/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 covers the procedures for calculating the viscosity index of petroleum products, such as lubricating oils, and related materials from their kinematic viscosities at 40 and 100o<\/sup>C.<\/p>\n

Note 1 — The results obtained from the calculation of VI<\/i> from kinematic viscosities determined at 40 and 100o<\/sup>C are virtually the same as those obtained from the former VI<\/i> system using kinematic viscosities determined at 37.78 and 98.89o<\/sup>C.<\/p>\n

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

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

1.2 This standard does not apply to petroleum products with kinematic viscosities less than 2.0 mm2<\/sup>\/s (cSt) at 100o<\/sup>C. Table 1 given in this practice applies to petroleum products with kinematic viscosities between 2 and 70 mm2<\/sup>\/s (cSt) at 100o<\/sup>C. Equations are provided for calculating viscosity index for petroleum products having kinematic viscosities above 70 mm2<\/sup>\/s (cSt) at 100o<\/sup>C.<\/p>\n

Note 2 – 1 cSt = 1 mm2<\/sup>\/s = 106<\/sup>m2<\/sup>\/s.<\/p>\n

1.2.1 In cases where kinematic viscosity data are not available at temperatures of 40 and 100o<\/sup>C, an estimate may be made of the viscosity index by calculating the kinematic viscosity at temperatures of 40 and 100o<\/sup>C from data obtained at other temperatures. Such viscosity index data may be considered as suitable for information only and not for specification purposes. See Test Method D 341, Annex A1.<\/p>\n

1.3 The kinematic viscosity values are determined with reference to a value of 1.0034 mm2<\/sup>\/s (cSt) at 20.00o<\/sup>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.<\/p>\n

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