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 500 Hz, 0.5 octave / minute sweep rate. This
requires one sweep, 10 to 500 to 10 Hz, along each of the three axes.
Random Vibration: 0.008 G2/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: 50 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: 35 G peak acceleration, 180 inches / second velocity change. There shall
be one shock in each direction in each axis, for a total of 6 shock inputs.
6.3 Display disturbances from external environment
According to IEC 801-2 for ESD disturbances
7.0 Reliability
7.1. Mean Time Between Failures
System MTBF (Excluding the LCD panel and CCFL): 75,000 hrs
CCFL MTBF: The lamps shall have a continuous operating life of at least 50,000 hours
at 25 C. The operating life is defined as having ended when the illumination
of light has reached 50% of the initial value. In addition to the minimum 50%
luminance at 50,000 hours, the backlights must also meet the requirement of
minimum 65% at 26,000 hours.
8.0 Quality assurance requirements
8.1 Acceptance test
According to MIL-STD-105D Control II level
AQL: 0.65 (major)

off stage, if any deviation between Sheet590 and customer specification, should follow up panel
specification.
10.1 Visual Inspection
The LCD panel shall be inspected with all pixels set to white, black, red, green, and blue. The color variation,
brightness variation and overall appearance must not be perceived as poor quality by Hewlett-Packard. Areas
and/or parameters considered questionable shall be
