Two high temperature hydraulic fluids were characterized as to their shear and thermal stress behavior in the environment of a new small-volume high- temperature evaluation stand. A dewaxed super refined mineral oil MIL-H-27601 was investigated at 550, 600, 625, and 700F and exhibited no significant degradation to 600F in the inerted system environment. A modified fluorosilicone MLO-70-79 was investigated at 600F and experienced a significant loss in viscosity 100F after 58 hours of environmental residence.
