Koehler – Tribology – Shear Stability Tester
Evaluates the shear stability of polymer-containing fluids. The test method measures the percent viscosity loss (and mm2/s for test method D7109) at 100°C of polymer-containing fluids when evaluated by a diesel injector apparatus procedure that uses European diesel injector test equipment.
The viscosity loss reflects polymer degradation due to shear at the nozzle. For D7109: Viscosity loss is evaluated after both 30 and 90 cycles of shearing.
