Shear Stability of Polymer Containing Fluids Apparatus

Shear Stability of Polymer Containing Fluids Apparatus TT-6278

Shear Stability of Polymer Containing Fluids Apparatus TT-6278 meets the ASTM D6278 standard, which assesses viscosity loss due to polymer breakdown in high-shear conditions using a European diesel injector. This method minimizes thermal and oxidative influences, ensuring accurate evaluation of shear stability.
