Additional testing: This deviation is considered as a reliability concern and additional tests must be conducted to check the system performance. From the point of view of the SAM inspection, such deviations do not comply with the acceptance criterion

Conclusion
The most frequently observed issues are addressed by all the analyzed specifications. Nonetheless, there are remarkable differences such as:
- The rejection thresholds
- Only in some methods additional tests and/or inspections are used to confirm suspected results and to further evaluate the actual impact on the systems performance, reliability and or durability
