specific cycle and back to 1g. The rate of cycling shall be approximately 3 cycles per minute.
The outlet pressure at the extreme forces of each cycle shall be as specified on figure 1 for the
applied force. After completing all phases of the cyclic operation, the valve shall be subjected to
and pass the inspection specified in 4.6.3, 4.6.4, 4.6.5, 4.6.6, 4.6.9, and 4.6.11.
4.6.11 Salt fog. The valve shall be subjected to a salt fog test in accordance with MIL-
STD-810, Method 509. The valve shall be examined for evidence of excessive corrosion.
4.6.12 Internal corrosion. With the valve maintained at a temperature of 135 + 5 °F, a salt
fog in accordance with the salinity requirements of MIL-STD-810, Method 509, at a temperature
of 135 + 5 °F, shall be passed through the valve in the normal direction of flow at approximately
3 flow cycles per minute for a duration of not less than 15 minutes. The rate of flow of salt fog
shall be not less than 30 liters per minute. This procedure shall be performed 10 times with the
valve dried after each 15 minute period. After completion of the above tests, the valve shall be
subjected to and pass the tests specified in 4.6.2, 4.6.3, 4.6.4, and 4.6.6.

4.6.13 Disassembly and examination. At the conclusion of all the inspections, the valve
shall be disassembled and examined. The valve shall not show evidence of excessive
deterioration or wear due to testing which might affect the valve performance. The valve shall
be disassembled and examined after any test in which valve failure indicates faulty construction.

PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified
in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-
house contractor personnel, these personnel need to contact the responsible packaging activity to
ascertain packaging requirements. Packaging requirements are maintained by the Inventory
Control Point's packaging activities within the Military Service or Defense Agency, or within the
military service's system commands. Packaging data retrieval is available from the managing
Military Department's or Defense Agency's automated packaging files, CD-ROM products, or
by contacting the responsible packaging activity.
