8. MECHANICAL REQUIREMENTS
8.1 Vibration and Shock
All testing shall be done in each of three mutually perpendicular axes, referenced to the
position of the system as it is in front of the user (i.e., front-to back, side-to-side, and top-to-
bottom).
8.1.1 Non-Operating
The unit should suffer minimal visible cosmetic damage or damage that presents a safety
hazard, or impairs the setup and operation of the system after testing.
Sinusoidal Vibration:
0.75 G zero-to-peak, 10 to 500Hz, 0.5 octave / minute sweep rate.
This requires one sweep, 10 to 500 to 10Hz, along each of the three axes.
Random Vibration:
0.008 G
2
/Hz, 10 to 500 Hz, nominal 2 GRMS. The test shall be for
one hour for each of the three axes.
Half Sine Wave Shock:
120 G peak, half sine pulse, 2 ms pulse duration. Testing shall
consist of one shock in each direction in each axis, for a total of 6 shock inputs.
Square Wave Shock: 40 G peak acceleration, 160 inches / second velocity change. There
shall be one shock in each direction in each axis, for a total of 6 shock inputs.
