... can be combined with data from operational tests to improve the information. Of course, part of the exploratory analysis will include checking for consistency among the developmental testing, operational testing, and other types of data, both empirically using extrapolations and using knowledge of the similarities and differences in the testing environments -- and even for components and subsystems when available.

... will depend on the component and failure mode of interest -- corrosion, fatigue, mechanical wear, etc. There is an extensive discussion of stress factors corresponding to different types of failure mechanisms in the engineering literature.3 There is also considerable literature on the planning, design, and analysis of accelerated testing for life tests, where the outcome is lifetime data.
