    If a complete module is going through environmental testing and once the test is finished the unit passes as OK a parametric testing (100% coverage), is it valid to use a rating assigned for degradation tests (D=2/5) for all the parameters which are checked in the parametric test?

    Quote Mr. Dr. Alexander Schloske:

    „From my point of view, I would evaluate this procedure with a detection of D=4 (OK-NOK test). I think, our problem with the new evaluation tables is, that we want to reduce the values towards D=1. But if we consider the evaluation tables in context with the action priority tables, a detection of D=4 is also with the severity of S=10 a low priority in the green area. We are no more talking about probabilities – instead we are discussing, if we have chosen the right testing strategy.“
