Expanded Information
The same product, in different stages, the test conditions are not the same; in general, the product will go through the research and development, small trial production, mass production of three different stages.
1, R & D stage, the most stringent test conditions (maximum stress), the shortest test continuation time;
2, small batch trial production stage, the test stress is moderate, the test time is moderate;
3, mass production stage, the test stress is minimum, the test time is shorter.
