MAINTENANCE FORMS, RECORDS, AND REPORTS
Department of the Army forms and procedures used for equipment maintenance will be those prescribed by
DA PAM 750-8. The Army Maintenance Management System (TAMMS) Users Manual; or AR 700-138, Army
Logistics Readiness and Sustainability.
REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIRs)
If your dump body needs improvement, let us know. Send us an EIR. You, the user, are the only one who can tell
us what you do not like about your equipment. Let us know why you do not like the design or performance.
All non-Aviation/Missile EIRs and PQDRs must be submitted through the Product Data Reporting and Evaluation
Program (PDREP) Web site. The PDREP site is: https://www.pdrep.csd.disa.mil/.
If you do not have Internet access, you may submit your information using an SF 368 (Product Quality Deficiency
Report). You can send your SF 368 using email, regular mail, or fax using the addresses/fax numbers specified in
DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual. We will send you a reply.
CORROSION PREVENTION AND CONTROL (CPC)
Corrosion prevention and control 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. The term "corrosion" means the deterioration of a material or its properties
due to a reaction of that material with its chemical environment. 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 (also considered to be corrosion based on the
above definition of corrosion). Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents),
or photolytic (light, typically ultraviolet) processes. The most common exposures are excessive heat or light.
Damage from these processes will appear as cracking, softening, swelling, and/or breaking. The US Army has
defined the following nine (9) forms of corrosion used to evaluate the deterioration of metals. These shall be used
UNIFORM (or general attack): Affects a large area of exposed metal surface, like rust on steel or tarnish on silver.
It gradually reduces the thickness of the metal until it fails.
CREVICE: Occurs in crevices created by rubber seals, gaskets, bolt heads, lap joints, dirt or other surface
deposits. It will develop anywhere moisture or other corrosive agents are trapped and unable to drain or
