This standard specifies methods for the simultaneous determination of dynamic viscosity and density of petroleum products in transparent and opaque liquids, and applies to liquids where shear stress and shear rate are proportional. The standard applies to the determination of dynamic viscosity and density, with precision examination of sample type, viscosity range and density range. Standard reference documents include transparent and opaque liquids Kinematic viscosity determination and density determination of petroleum products. In the definition of terms, dynamic viscosity is a measure of the internal friction of a flowing liquid under a certain shear stress, while kinematic viscosity is the ratio of dynamic viscosity to liquid density.
