Every entry in the Defense records system exists because some decision needed a documented basis, and DD Form 1213 is one of those instruments: DD Form 1213, Unconfined Compression Test, August 1957, created to Compression Test, Unconfined. The reason it carries a DD number rather than a service designation is structural — the Department maintains a single body of forms for matters that arise identically in every service, so that a record created in one component remains intelligible in another.
That decision has consequences you will notice. Because not stated prescribes the form for the Department as a whole, and not stated maintains it on the Department's behalf, the same blank passes between the Army, the Navy, the Air Force, the Marine Corps, the Space Force, the Coast Guard when operating under Defense jurisdiction, the defense agencies and the combatant commands without translation. A clerk in one component reads a record created in another and finds the fields where they expect them.
You are looking for edition not stated, listed as not stated. Department-wide supersession is a single event rather than a rollout, which is what distinguishes edition currency on a DD form from the same question on a service publication: nobody anywhere is still accepting the previous version out of habit.
Work down the page in the printed order, and understand why the order exists. The identifying block establishes whose record this is and under what circumstances it arises. The body of the form then answers questions that are only meaningful once that context is fixed. The signature block comes last because a certification signed before the entries are complete certifies nothing.
Verify the printed edition against not stated first. Field structure shifts between editions, and the office that receives your record is reading the current one. That office may sit outside your service, which removes even the informal accommodation you might expect from a colleague who used the old version last month.
For an ambiguous field, read the form's own instruction, then not stated, which controls.
Download the form
Formats available: PDF, across 1 pages and about 200 fields. That several formats coexist is a consequence of scale — the Department cannot standardize the software on every desk that needs this form, so it standardizes the document instead.
The difference between a fillable and a printable pdf is a difference in what the file contains. A fillable release carries an interactive layer: each box is a defined field with a name and a data type, and what you type is stored as data inside the document. A printable release has no such layer — it is an image of the page, and the only place your answers can go is onto paper. The distinction matters downstream, because a Department record often gets scanned and forwarded several times before it reaches its final file, and typed characters survive that chain in a way pen strokes do not.
If you find an xfdl file here, its presence is historical. The format belongs to IBM Lotus Forms, which the Department adopted Department-wide for electronic forms and fielded on a scale that makes wholesale removal slow. You need the matching viewer to open it; ordinary pdf software cannot read the format and will say so unhelpfully.
All of it downloads without charge. Where care is needed is in the reader you choose. A fillable pdf depends on field properties that desktop applications honour and browser previews frequently ignore, so work locally rather than inside a browser window.

The completed form goes to the office named in not stated or in local implementing procedure, and it is worth keeping a copy before it goes. On a Department form the destination is frequently outside your own chain — another service, a defense agency, a joint staff — and recovering a document that has crossed an organizational boundary is a slower business than retrieving one from a file down the hall.
Forms referenced inside this one are located by number alone, and that simplicity is a direct product of Department-level numbering. Because the DD sequence is maintained centrally and not duplicated by service, a number is a complete address: one number, one document, throughout the Defense establishment.
It helps to see the DA and DD sequences as what they are: separate registries with separate custodians. One serves a single service under a service proponent, the other serves the Department under not stated or an equivalent office, and neither was ever indexed against the other. A number that appears in both systems points to two unrelated documents, which is why reading the prefix comes before reading the digits.
Understanding why editions change explains why checking them is not optional. Revision follows directive reissue, changes in what data is required, and amendments to mandatory notice text — decisions made at Department level and communicated through publication rather than notification. The file you saved does not update itself, so the edition date at download is what you rely on.
A word on what this page is. It distributes a published Department of Defense document and describes what the document contains and how it is completed. It is not the issuing authority, does not speak for one, and offers no legal advice; nothing written here determines whether a particular submission will be accepted, because that determination belongs entirely to the office receiving it. Questions of applicability, eligibility or procedure go to not stated, to your servicing personnel office, or to the office identified in not stated.
