Appendix 6 - Design Verification Test Procedure
B.1 Purpose
This standard establishes the environmental specification for projector related products, which
defines the level of product performance and reliability in the field. It is not necessary the intent of
these specification to simulate a typical user environment, but rather to provide for a level of product
robustness that when applied over a wide range of manufacturing variability and environmental usage
conditions, which is recommended for product assurance testing reference.

Criteria *A *B
Test Orientation: 1 corner, 3 edges, 6 faces
Criteria:
1. Criterion *A: After testing, no abnormality on function
and appearance, brightness and uniformity deviation
must be /- 5%.
2. Criterion *B: After testing, no abnormality on function
and appearance. (This is tightened spec to double
check design margin on R&D stage only.)
3. No broken issue on carton.
4. No broken issue on cushion, but cracks acceptable.
Package Vibration Test condition :
1. Sine wave:
5~200Hz 1.5G, 1 octave/min, 15 min dwell on each resonant
frequency, all primary axis, one sweep 30 minutes/Min. per
orientation, total of 90+ min.
2. Random wave:
5-100Hz 0dB/Oct. 0.015(g2/Hz)
100-200Hz -6dB/Oct. N/A
200Hz N/A 0.0038(g

/Hz)
Equivalent to 1.47 Grms, all primary axes, 20 min
per-orientation, total of 60 min.
Note: Perform random vibration test before, the Sine-wave
vibration should be done first.
