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 desktop 
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

The use environment expectations assumed are for desktop processors, based on an expected life of 
7 years, are listed in 
The target failure rates are <1% at 7 years (and <3% at 10 years).
