How Long do I Need to Test? Part 1: Basic Considerations

2022年 2月 3日 | Dr. Oliver D Rahaeuser

教育

The question about the right test duration is an important question because time especially during product development is valuable. The best approach to answer this question is first to identify the motivation, why we are going to run a weathering test. In my experience, most weathering tests can be split into three different categories:
