CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any
corrosion problems with this item be reported so that the problem can be corrected and improvements
can be made to prevent the problem in future items.
While corrosion is typically associated with rusting of metals, it can also include deterioration of other
materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these
materials may be a corrosion problem.
If a corrosion problem is identified, it can be reported using Standard Form SF 368, Product Quality
Deficiency Report. Use of keywords such as "corrosion,” "rust," "deterioration," or "cracking" will ensure
that the information is identified as a CPC problem.
The form should be submitted to the address specified in DA PAM 738-750, Functional Users Manual for
the Army Maintenance Management System (TAMMS).
