5 Environmental Requirements
Design, including materials, shall be consistent with the manufacture of units that meet
the following environmental reference points.
The reliability targets in this section are based on the expected field use environment
for a server product. The test sequence for new sockets will be developed using the
knowledge-based reliability evaluation methodology, which is acceleration factor
dependent. A simplified process flow of this methodology can be seen in Figure 5-1.
A detailed description of this methodology can be found at:

.
The use condition environment definitions provided in Table 5-1 are based on
speculative use condition assumptions, and are provided as examples only.
