4.6.10 Shock. The valve shall be subjected to high-impact (H.I.) mechanical shock tests in accordance with the
requirements for Grade A, subsidiary component, Class I, lightweight, Type B, Fixture 4A of MIL-S-901. A valve
will be considered to have failed the shock test if it will not meet the leakage test (qualification) requirements of
4.6.3.1, checking time requirements of 4.6.4.1, cracking pressure requirements of 4.6.4.2, or shows any signs of
external or internal damage when examined in accordance with 4.5.1.1 and 4.5.1.2. The valve shall be pressurized
to the maximum operating pressure specified in 3.5.1. Shock tested valves will be post shock test examined and
retained by the qualifying activity.
4.6.11 Structureborne noise. The valve shall be tested and shall comply with the structureborne noise
requirements of 3.5.13.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or
