Demilitarization Code:DMunitions List Item or Commerce Control List Item. Demilitarization required. Total destruction of the item and components so as to preclude restoration or repair to a usable condition by melting, cutting, tearing, scratching, crushing, breaking, punching, neutralizing, etc. (As an alternate, burial or deep water dumping may be used when coordinated with the DoD Demilitarization Program Office.)
Electro-static Discharge Susceptible:ANo known Electrostatic Discharge (ESD) or Electromagnetic Interference (EMI) sensitivity
Precious Metals Indicator Code:AItem does not contain precious metal
Criticality Code:X The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
Automatic Data Processing Equipment:4ADP Input/Output and Storage Devices Used to Control and Transfer Information to and from a CPU. The input device is used for transferring data and instructions into a CPU. The output device is used to transfer results of processing by the CPU onto printed forms, punched cards, and/or magnetic media. Input/output devices combine the above functions in the same device. This class also includes data transmission terminals, batch terminals, and display terminals which are specially designed or modified to be used in conjunction with digital, analog, or hybrid CPUs. It includes modems when they are integral to the terminal. It also includes storage devices in which data can be inserted, retained, and retrieved for later use.
