What it is
A recommendation, not an obligation
STANREC 4750 is a NATO Standardization Recommendation covering advanced data storage technology memory systems sanitization. Like every STANREC, it stops short of a STANAG's ratified commitment: the document states plainly that it "is a non-binding document employed on a voluntary basis and does not require commitment of the nations to implement the standards which are listed in it." Nations are free to use the practice it points at, or not, and nothing in the STANREC itself creates an obligation a supplier signs up to directly.
What it recommends, and what it does not
The stated aim is "to list recommended practices regarding: proper data purge and sanitization techniques for advanced technology memory systems," and the document is specific about which devices it has in view: "FLASH solid-state, Solid State disk (SSD) and advanced magnetic disk and disk array storage devices used in ISR systems." What it recommends nations use is a single named publication, "AEDP-3, Edition C, Version 1", the Allied Engineering Publication that carries the sanitization guide this STANREC's own title borrows. STANREC 4750 itself sets out no purge method, no overwrite count and no parameter for any of these device types. That content is AEDP-3's, not this cover document's, and this page has not read AEDP-3.
Superseded arrangement
This edition "supersedes the following document: AEDP-3 edition 2, 8 September 2009." The earlier arrangement pointed at an older edition of the same underlying publication; this STANREC updates the recommendation to Edition C, Version 1.
Review, and how changes reach it
STANREC 4750 "is to be reviewed at least once every three years," with the outcome recorded in NATO's Standardization Document Database. Outside that cycle, "nations and NATO bodies may propose changes, at any time, through a standardization proposal to the tasking authority" - the Joint Capability Group on ISR, which supervises this STANREC.
Where the actual sanitization guidance lives
Two further documents are named for context: STANAG 4575, Edition 4 (NATO Advanced Data Storage Interface), and NIST Special Publication 800-88, Sanitization Guidelines, published by the US National Institute for Standards and Technology. Neither is a requirement of this STANREC; both are named as related reading. The document that actually carries the sanitization techniques is AEDP-03, the publication STANREC 4750 recommends. What counts as adequate sanitization for a given classification of data is, in every case, a decision for the national security authority responsible for that data, not something this STANREC, AEDP-3, or a vendor sets.
