ASTM D7152-05<\/h3>\n

Historical Standard: Standard Practice for Calculating Viscosity of a Blend of Petroleum Products<\/h4>\n
\n

ASTM D7152<\/h4>\n

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

1.1 This practice covers the procedures for calculating the estimated kinematic viscosity of a blend of two or more petroleum products, such as lubricating oil base stocks, fuel components, residua with kerosine, crude oils, and related products, from their kinematic viscosities and blend fractions.<\/p>\n

1.2 This practice allows for the estimation of the fraction of each of two petroleum products needed to prepare a blend meeting a specific viscosity.<\/p>\n

1.3 This practice may not be applicable to other types of products, or to materials which exhibit strong non-Newtonian properties, such as viscosity index improvers, additive packages, and products containing particulates.<\/p>\n

1.4 The values stated in Si units are to be regarded as stnadard. No other units of measurement are included in this standard.<\/p>\n

1.5 Logarithms may be either common logarithms or natural logarithms, as long as the same are used consistently. This practice uses common logarithms. If natural logarithms are used, the inverse function, exp(\u00d7), must be used in place of the base 10 exponential function, 10\u00d7:<\/sup>, used herein.<\/p>\n

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n
