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.
