Appendix B Design Verification Test Procedure
B1. 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.

B3 Definition
Failure Criteria:
The product is expected to perform to its full potential without loss of function, performance,
critical parametric changes, and other undesirable anomalies, over the applied boundaries of this
specification. The following product failure are not allowed within the boundaries defined in this
specification:
1. Failure including permanent damage, critical parametic changes (optical performance
defined in Appendix A), and latent defects.
2. Failure requiring operator intervention.
3. Failure violating external laws, regulatory agency standards, and government directives.
4. Failure resulting in a safety, potential safety, issue.
