TM 9–1200–215–34&P 1–3 1–9. CORROSION PREVENTION AND CONTROL (CPC) a. Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosion problems with the item be reported so they can be corrected and improvements can be made to prevent the problem in future items. b. 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. c. If a corrosion problem is identified, it can be reported using SF 368, Product Quality Deficiency Report. Use key words such as corrosion, rust, deterioration, or cracking to ensure that the information is identified as a CPC problem. d. SF 368 should be submitted to: Department of the Army, U.S. Army Tank–automotive and Armaments Command, Armament Research, Development and Engineering Center, ATTN: AMSTA–AR–QAW–C, Rock Island, IL 61299–7300. 1–10.
