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 SF Form 368 (Product Quality Deficiency Report). Use of key

words 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.

DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE

For destruction of Army materiel to prevent enemy use, refer to TM 750-244-6.
