prevent the problem in the future. While corrosion is typically associated with rusting of metals, it
can also include deterioration of other materials such as rubber and plastic.
softening, swelling, or breaking of these materials may be a corrosion problem.
If a corrosion
problem is identified, it can be reported using SF 368 (Product Quality Deficiency Report).
