Physical and Performance Tests for Type II (-65 to +275 \mDF) O-Ring Packings, 3000 psi Hydraulic Service ( Reaffirmed: Jul 1992 Dec 2007 )
This document outlines proposed test methods for the qualification of O-ring packings intended for use in aircraft hydraulic systems utilizing MIL-H-5606 fluid at rated service pressures up to 3000 psi and temperatures ranging from -65 to 275 F. It will also serve as the basis for the future preparation of a complete packing specification after basic elastomer types have been established by capability of performance.
