CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (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.
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. If
a corrosion problem is identified, it can be reported using SF Form 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.
OZONE DEPLETING SUBSTANCES
No ozone depleting substances are used in maintenance of 621B Scraper.
