CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corro-
sion 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. Corro-
sion 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 (oxy-
gen), solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures are exces-
sive heat or light. Damage from these processes will appear as cracking, softening, swelling, and/or breaking.
If a corrosion problem is identified, it can be reported using SF 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, Functional Users
Manual for The Army Maintenance Management Systems (TAMMS).
OZONE DEPLETING SUBSTANCES
There are no Ozone Depleting Substances (ODS) contained in the ROWPU system.
