- Test item is visually inspected for elongation, wear, deformation, and missing capacity markings.
- The test item is inspected for cracks that can not be seen by the naked eye using a Liquid Penetrant test
- The part is cleaned with a special cleaner.

- The liquid penetrant is cleaned away after the manufactures designated time.
- The part is sprayed with a developer spray.
