You have arrived looking for DD Form 1209. Before you download, confirm this is the right document: Liquid- and Plastic-Limits Determination. Full title: DD Form 1209, Liquid- and Plastic-Limits Determination, December 1999.
Next, check the edition. You want not stated, currently carried as not stated by the publisher. Then confirm the form applies to you — this is a Department of Defense form, so you use it whether you serve in the Army, Navy, Air Force, Marine Corps, Space Force or Coast Guard under Defense jurisdiction.
Once you know the form fits, find out when you file it. not stated sets the requirement, and not stated maintains the form itself. Your own command or agency adds local timing on top of that, so ask your administrative office if the deadline matters to you.
Before you download, pick your approach — editable file or printed page. What follows covers the formats first, then the entries, then what you do afterward.
Begin at the top and move down. Enter your identifying data first, then the body of the form, then the signature block. The sequence is printed in that order because entries below frequently follow from entries above.
Your first action is verification. Find the edition date on the form and match it against not stated. A mismatch means you are working from a superseded printing, and because DD forms change Department-wide rather than service by service, the office receiving it will notice.
If a particular field puzzles you, read the instructions printed on the form first, then go to not stated. When the two disagree, follow the directive.
Download the form
Begin by choosing a file. Available here: PDF. Plan for 1 pages and about 117 entries.
Whichever you pick, you pay nothing — every format here is a free download. One last tip: open your pdf in a desktop reader rather than in a browser tab, because browser viewers sometimes drop the interactive fields you need.

With the form finished, route it to the office named in not stated or in your organization's own instruction. Keep a copy first. People rarely regret having one and frequently regret not having one.
When DD Form 1209 references another form, search on the series and number. Because DD numbers are common to every military department, the number by itself identifies exactly one document.
Here is where people go wrong. They see a number in an instruction and download whichever form matches it. But DA and DD are separate systems — Army-specific in one case, Department-wide under not stated in the other — so check which series you were sent to before you take the file.
Come back and check the edition next time you need this form. Editions change when the prescribing directive is reissued, when the information collected changes, or when the required notice language is updated, and none of those events reaches you directly. Verifying not stated at the moment you download is the whole defence.
Finally, understand the limits of what you have read. This page distributes a published Department of Defense form and describes how to fill it out. It does not give legal or procedural advice, and it cannot promise any outcome for your particular case. For that, contact not stated, your administrative office, or the authority identified in not stated.
