ASTM D6080 for defining the viscosity characteristics of hydraulic fluids
ASTM D6080 for defining the viscosity characteristics of hydraulic fluids4. Summary of Practice4.1 High VI hydraulic fluids often contain high molecular weight thickeners, called viscosity index (VI) improvers, which impart non-Newtonian characteristics to the fluid. These polymers may shear degrade ...
