CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army material 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. Corrosion speciically occurs with metals. It is an electrochemical
process that causes the degradation of metals. It is commonly caused by exposure to moisture, acids, bases,
or salts. An example is the rusting of iron. Corrosion damage in metals can be seen, depending on the metal,
as tarnishing, pitting, fogging, surface residue, and/or cracking. Plastics, composites, and rubbers can also
degrade. Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents), or photolytic (light,
typically ultraviolet (UV)) processes. The most common exposures are excessive heat or light. Damage from
these processes will appear as cracking, softening, swelling, and/or breaking. SF Form 368 (PQDR) should be
submitted to the address speciied in DA PAM 750-8, TAMMS Users Manual.
DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE
Instructions for destruction of this equipment are contained in Technical Manual (TM) 750-244-1-4, Procedures for
