NATIONAL COMPUTER SECURITY CENTER DEGAUSSER PRODUCTS LIST 27 February 1989 INTRODUCTION TO THE DEGAUSSER PRODUCTS LIST The Degausser Products List (DPL) lists the model identification of equipment units that were evaluated against and found to satisfy the requirements for erasure of magnetic media that hold classified data. A commercial production unit of each model of degausser was evaluated against Department of Defense (DOD) requirements for erasure of classified tapes as set forth in DoD Manual 5200.28-M, "Techniques and Procedures for Implementing, Deactivating, Testing, and Evaluating Secure Resource-Sharing ADP Systems," dated January 1973, Section VIII, Specifications For Magnetic Tape Erase Equipment. The National Security Agency/Central Security Services (NSA/CSS) has implemented the Manual's specification in NSA/CSS Specification L14-4, dated 31 October 1987. Listing of a product on the DPL does not constitute endorsement of the product by the government or NSA, it merely indicates that the unit evaluated has met all applicable degausser requirements. Moreover, though listed in the DPL, products must be periodically tested to ensure continued compliance with the specification. NSA/CSS Specification L14-4, Section 5, Degaussing Level Performance Test Procedures, gives a test procedure that users may follow to verify continued compliance with the specification. Magnetic media are divided into types. Type I products are used to degauss magnetic media whose coercivity is no greater than 350 Oersteds (Oe). Type II products are used to degauss magnetic media whose coercivity is no greater than 750 Oe. Coercivity of a magnetic media defines the magnetic field necessary to reduce a magnetically-saturated material's magnetization to zero. The correct use of degaussing products will ensure that classified data is no longer retrievable. NOTE: IN ADDITION TO DEGAUSSING, CERTAIN ADMINISTRATIVE PROCEDURES MAY BE REQUIRED BEFORE DEGAUSSED MAGNETIC MEDIA MAY BE DECLASSIFIED. CONSULT YOUR SECURITY OFFICER OR MANAGER FOR GUIDANCE IN THIS REGARD. Correct use of these equipments is necessary to ensure inadvertent disclosure of classified information does not occur. Accordingly, users having operational questions about the equipment should direct their questions to the manufacturer. Questions regarding security requirements should be addressed to your Security Officer or manager.

When using this model for tape reels wider than 1/2 inch, the tape must be turned over and degaussed a second time. 3. PERMANENT MAGNET DEGAUSSERS 3.1 Hand-held Degaussers - These are hand-held permanent magnets that have satisfied the requirements to degauss Type I magnetic recording media. Floppy disks, disk packs, disk platters, magnetic drum surfaces, bubble memory chips, and thin film memory modules may be degaussed with these degaussers. To degauss disk packs, cover the hand-held magnet with a lintless tissue, wiping cloth, or layer of thin plastic as a means of preventing damage to the recording surface. Insert the degaussing wand into the disk pack so that the active magnetic portion completely covers the recording surface of the disk from hub to perimeter. Wipe each active disk surface (top and bottom) at least three times with the magnet. Applied Magnetics Lab. 42-P-MEM 1404 Bare Hills Rd.
