So what is DD Form 1794? The short answer: a Defense Department document, officially DD Form 1794, Grain-Size Analysis (Hydrometer Method), December 1999, used to Grain-Size Analysis (Hydrometer Method). Anything else you need follows from that.
Will you need a different form because of where you serve? No. DD forms are Department-wide instruments, and that scope is what separates them from service publications. One edition, all branches, defense agencies included.
Who decides this form exists? not stated owns it; not stated directs its use. If someone told you to file this, the authority traces back to those.
Which edition should you have? not stated, listed as not stated. A copy dated otherwise is a copy worth replacing.

Download the form
What formats exist for this form? PDF. What is the scale of it? 1 pages and approximately 122 fields.
Fillable or printable — which do you have? Click inside a box. If it accepts a cursor and typed text, the file is fillable and your entries save with it. If nothing happens, the pdf is flat, and the only way forward is printing it and writing on paper.
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.
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.
Can you leave fields blank? Not safely. A reviewer cannot tell a deliberate omission from a missed question, so mark inapplicable items N/A. And date fields? Match the format shown on the form — conventions differ, and misreading a date is easy.
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.
What counts as a signature? Ink on a printed copy, or a credentialed digital signature — CAC-based, applied in software that supports it. What does not count? Your name typed into the signature box. That is a name. Then date the block, because an undated certification is a returned form.
Which mistakes are worth a final check? Superseded edition, gaps in mandatory fields, unreadable writing on a scanned copy, non-conforming date format, unsigned or undated certification.
Is the form its own instruction manual? Partly. The rest sits in not stated, which is also the authority where the two texts conflict.
What happens after you finish? It routes to the office specified in not stated or in local guidance. And your own record? Save a duplicate first; nobody regrets having one.
What if DD Form 1794 points to another form? Search the series and number. Because the DD sequence is common to every military department, no branch qualifier is needed to land on the right file.
Can you assume a matching number is the same form? No, and this is where downloads go wrong. Read the prefix. Army numbering and Department numbering are independent systems, so the digits alone tell you nothing about which document you need.
How often does a form like this change? Unpredictably — revision follows directive changes, altered collection requirements and updated notice language. What is the practical defence? Verifying not stated every time you download rather than trusting a saved copy.
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.
