6. MECHANICAL REQUIREMENTS

6.1 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).
6.1.1 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
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.
