Product RequirementsAll products which undergo testing are manufactured using the standard process.5. Testing RequirementsAll products are tested at the scheduled intervals as outlined in the test datasheets or as dictated bythe test standard specific to the individual test.Definition of Electrical Failure: Components that are no longer generating valid output voltageare considered hard failures. These components must be evaluated to root cause. Changes inelectrical performance (parameters outside acceptable tolerance limits of specification) or electricalfailures caused by thermal transitions require that Vicor perform an evaluation.Corrective Action – All product failures must be fully investigated, determining root cause andassigning corrective actions as deemed appropriate.Page 13 of 13
