4.6 Tests.
4.6.1 Examination. The actuator shall be examined for compliance with the requirements for
materials, fillets, wrench flats, seals, bearings, scraper and wiper rings, bosses, end caps,
locknuts, adjustment nuts, rod bearing length, ports, rod bearing overlap, interchangeability, and
item identification.
4.6.2 Salt fog. The actuator shall be subjected to the salt fog test in ASTM B117 for 50 hours.
The actuator shall then be subjected to the leakage test.
4.6.3 Immersion. Type I actuators containing nonmetallic parts, other than standard seals and
backup rings in glands conforming to SAE AS4716, shall be immersed in hydraulic fluid for
seven days at 160°±2°F. Type II actuators containing nonmetallic parts shall be immersed in
hydraulic fluid for 72 hours at 275°±5°F. The actuator shall then be subjected to the individual
tests.
4.6.4 Hydraulic properties. The actuator shall be tested in accordance with SAE AS8775.
4.6.5 Vibration. The actuator shall be subjected to the vibration test in RTCA/DO-160 at the
levels specified in the associated specification.
4.6.6 Leakage. The actuator shall be cycled with the piston unrestrained for at least 100 cycles.
Pressure shall build up to system pressure at the end of each stroke. Leakage at points where
motion through external packing exists shall not exceed the rate of one drop per packing per 25
