CORROSION PREVENTION AND CONTROL (CPC)
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.
Corrosion specifically 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
Plastics, composites, and rubber compounds can also degrade. Degradation is caused by thermal energy (heat),
oxidation (oxygen), solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures
are excessive heat or light. Damage from these processes will appear as cracking, softening, swelling, and/or
SF Form 368, Product Quality Deficiency Report, should be submitted to the address specified in PAM 750-8,
TAMMS Users Manual.
There are no ozone-depleting substances contained on the machine or used during machine maintenance.
