適用范圍：This International Standard describes two procedures for calculating the viscosity index (VI) of petroleum products and related materials, such as lubricating oils, from their kinematic viscosities at 40 ℃ and 100 ℃. Procedure A is applicable to petroleum products of viscosity index up to and including 100. Procedure B is applicable to petroleum products of viscosity index 100 or greater. NOTE The results obtained from the calculation of VI from kinematic viscosities determined at 40 ℃ and 100 ℃ are virtually the same as those obtained from the former VI system using kinematic viscosities determined at 37,78 ℃ and 98,89 ℃. This International Standard does not apply to petroleum products with kinematic viscosities tess than 2,0 mm
