4.5.4.6 Vibration (nonoperating). To determine conformance to 3.5.6, the motor shall
be tested in accordance with vibration in the form of simple harmonic motion, in three mutually
perpendicular axes, and consisting of twelve 15 minute logarithmic sweeps along each axis for a
total of 9 hours.
4.5.4.6.1 Test condition (10 g peak). The motor while deenergized or operating under
load shall be subjected to the following frequencies and amplitudes.
Frequency
Amplitude
5 to 6.2 hertz (Hz)
0.5 in (12.7 millimeters (mm) double amplitude
6.2 to 25 Hz
+1 gravity unit (g)
25 to 200 Hz
+ 0.5 g
4.5.4.7 Proof pressure. To determine conformance to 3.5.7 the motor shaft shall be
clamped to prevent rotation and the outlet port connected to the drain. Apply not less than
6000 psi (41 000 kPa) to the inlet port. The motor shall be capable of meeting the performance
requirements of 3.4 after the test.
4.5.4.8 Burst pressure. To determine conformance to 3.5.8 the motor shaft shall be
clamped to prevent rotation and the outlet port connected to the drain. Apply not less than
12 000 psi (82 800 kPa) to the inlet port. The motor shall be capable of meeting the performance
requirements of 3.4 after the test.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified
in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD
personnel, these personnel need to contact the responsible packaging activity to ascertain requisite
packaging requirements. Packaging requirements are maintained by the Inventory Control Point's
packaging activity within the Military Department or Defense Agency, or within the Military
Department's System Command. 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.
6. NOTES
(This section contains information of a general or explanatory nature which may be
helpful, but is not mandatory.)
