PETROLEUM AND RELATED PRODUCTS - DETERMINATION OF THE SHEAR STABILITY OF POLYMER-CONTAINING OILS USING A DIESEL INJECTOR NOZZLE
01-12-2013
Describes a method to assess the resistance to shear stresses applied to mineral oils, synthetic oils, and other fluids containing polymers, when passed through a specified diesel injector nozzle. The shear stability is measured by the change in viscosity of the fluid under test, brought about by the polymer degradation during stress.
