6.2.2
Vibration and Shock
Product shall meet the operating, non-operating and pack test requirements of HP s specification for Monitor
Environmental and Reliability Testing (rev 6.0 of Oct. 21, 2002). Drop heights shall be determined by Compaq
specification 109291.
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).
6.2.3
Operating Conditions
The unit should suffer no visible cosmetic damage and should operate with no degradation in display quality
during exposure to the operational conditions.
Sinusoidal Vibration: 0.25 g zero-to-peak, 10 to 500 Hz, 0.25 octave / minute sweep rate. One sweep, 10 to
500 to 10 Hz, along each axis.
Random Vibration: 0.002 G2/Hz, 10 to 500 Hz, nominal 1.0 Grms in each of the three axes. The test duration
shall be sufficient so that the monitor's performance can be completely evaluated.
Half Sine Wave Shock: 30 G peak acceleration for 2 milliseconds duration in each of the three axes. The
number of shock inputs in each direction shall be sufficient so the monitor's performance can be evaluated.
