Importance of Physical and Chemical Properties of Aircraft Hydraulic Fluids

2011-02-08

HISTORICAL

AIR81C

This document discusses the relative merits of the physical and chemical properties of hydraulic fluids in relation to the aerospace hydraulic system design, and the related materials compatibility. The discussion in this report applies both to hydrocarbon and phosphate ester based aircraft hydraulic fluids. In some cases, numerical limits are suggested, but, in general, the significance and effect of a property is noted qualitatively.

PROCEDURE FOR THE DETERMINATION OF PARTICULATE CONTAMINATION IN HYDRAULIC FLUIDS BY THE CONTROL FILTER GRAVIMETRIC PROCEDURE

1963-02-01

HISTORICAL

ARP785

This procedure describes a gravimetric method for the determination of particulate contaminant in hydraulic fluids by the control filter technique. With this method detectable contamination levels down to 0.2 mg per sample can be obtained with a standard deviation of ± 0.1 mg.
