INDU S T RY T E S T R E SULT S WAT E R TOL E R A NC E W E A R T E S T The Water Tolerance Wear Test measures a fluid's ability to protect against corrosive wear. Castrol UTF, pitted against a competitive fluid during 0.4% and 1.0% water contamination, guarded against wear four times better than the competitor. SUN S T R A ND H Y DR AUL IC PUMP P E R F OR M A NC E T E S T During the Sunstrand Hydraulic Pump Performance Test, a fluid is contaminated with water and the loss of flow from the pump is measured. Flow degradation is an indicator of how well the fluid would still perform when contaminated. Castrol UTF showed only 0.6% flow rate degradation on a Sunstrand Piston Pump Model 22‑2132. The maximum allowable flow rate degradation is 10%.
