So what is DD Form 1213? The short answer: a Defense Department document, officially DD Form 1213, Unconfined Compression Test, August 1957, used to Compression Test, Unconfined. Anything else you need follows from that.
Does it apply to your branch? Yes. The DD prefix means Department of Defense, not one service, so the same blank serves the Army, Navy, Air Force, Marine Corps, Space Force and the Coast Guard under Defense jurisdiction. There is no Army version and no Navy version to search for.
Who is behind it? not stated maintains the form, and not stated is the publication that requires it. Those two names answer most questions about why you are being asked to submit anything at all.
Which edition should you have? not stated, listed as not stated. A copy dated otherwise is a copy worth replacing.

Download the form
Which files are here? These: PDF. How much work is involved? 1 pages, about 200 entry fields.
Why do two kinds of pdf exist? Because two kinds of user exist. One completes the form on screen and forwards a file; the other prints a blank and fills it by hand. The fillable release has interactive boxes, the printable release is a static image of the same page.
Is handwriting acceptable? Yes, but it is the weaker choice. Scanning flattens pen strokes and reproduction blurs them, while typed characters survive the whole chain intact. Print in capitals if you are working from a paper blank.
Is xfdl worth downloading? Only if you have the viewer. The format comes from IBM Lotus Forms, which carried Defense form distribution for a long stretch, and no ordinary pdf application will read it.
Do you pay for these? No. Free download, every format. What should you avoid? Filling the form inside a browser tab; the fields frequently do not save.
Can you skip around the form? Better not to. The layout runs identification, then content, then certification, and entries near the bottom frequently take their meaning from what sits above them.
Why does the edition matter so much here? Because DD forms are revised centrally. When the Department reissues one, it reissues it for all branches simultaneously, and the field layout can shift. Compare the printed date against not stated before you type anything.
What about a box that does not apply to you? Enter N/A rather than leaving it empty. An empty field reads as an oversight and sends the form back; N/A reads as an answer. What about dates? Use the format printed beside the field, not the one you write by habit.
What does the Privacy Act notice cover? Four things: the legal authority behind the collection, the purpose, the routine uses, and whether disclosure is required. When should you read it? Before entering personal information, while the choice is still open.
How do you sign electronically? With a digital signature, usually CAC-based, in a reader that handles it. Will typing your name work? Not as execution — it fills a field without certifying anything. Either way, the date goes in immediately after.
What sends forms back most often? An obsolete edition, blank required boxes, handwriting illegible after scanning, dates in a format the form did not ask for, and certification without a signature or without a date.
Where do you look up an unclear entry? The form face first, not stated second. And when the two disagree? not stated controls.
Who receives it? The office not stated designates, subject to whatever local instruction your organization adds. What do you keep? A copy, made before the form leaves your hands.
How do you find a form referenced inside this one? By its number alone. The DD sequence runs across the entire Department, so a number identifies exactly one document regardless of which service cited it.
Do DA and DD numbers ever correspond? Never. DA numbering is Army-specific, administered by an Army proponent, while DD numbering is Department-wide under not stated or an equivalent Department office. Identical digits in the two systems mean two unrelated documents, which is why the prefix matters more than the number.
Should you archive this file and reuse it next year? Better not. Forms are revised as directives are reissued, as data requirements shift and as statutory notice text is updated, and none of that reaches you directly. Download fresh, check the edition date.
Will your completed form be accepted? That is not a question this page can answer. What you have here is a published Department of Defense document, a description of it and instructions for filling it out. Nothing on the page is legal advice, and nothing here determines what any office does with a submission. Where do the remaining questions go? To not stated, to your servicing personnel office, or to the office named in not stated.
