Every entry in the Defense records system exists because some decision needed a documented basis, and DD Form 1794 is one of those instruments: DD Form 1794, Grain-Size Analysis (Hydrometer Method), December 1999, created to Grain-Size Analysis (Hydrometer Method). 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.
This is why the arrangement matters to you rather than only to the archivists. not stated governs the form throughout the Department, with not stated as the responsible office, so the record you create is legible outside your own component. Joint assignments, agency details and cross-service transactions all depend on that: the paperwork does not have to be reconstructed each time it crosses a boundary.
The edition in force is not stated, carried by the publisher as not stated, and edition discipline is stricter on a Department form than most people expect, precisely because supersession happens everywhere at once. There is no interval during which one service still works from the previous layout while another has moved on.
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.
Fill all of it, marking inapplicable items N/A. A record with gaps cannot later demonstrate whether the gap was a decision or an oversight, which is exactly the ambiguity documentation exists to remove. Dates go in the form's own format — on a document that crosses service lines, an ambiguous date is a real hazard rather than a pedantic one.
The Privacy Act Statement is not boilerplate appended for legal cover; it is the mechanism by which a statutory obligation is discharged at the moment of collection. When the government asks an individual for personal information, it must state the authority under which it asks, the principal purpose, the routine uses to which the data may be put, and whether answering is voluntary or mandatory. Those four disclosures are placed ahead of the data fields deliberately, because the point of telling you is to inform a choice you have not yet made.
What the signature block asks for is an act, not a text. Ink on a printed copy performs that act; a digital signature bound to your credential performs it electronically, CAC-based in most Defense systems. Typing your name performs nothing, since anyone with the file could type the same characters. Enter the date at the same moment: the certification is a statement about a point in time and needs one recorded.
The defects that return forms are the same ones year after year: a superseded edition, required fields left blank, handwriting that fails on reproduction, dates in a convention the form did not ask for, and certification without a signature or without a date. Where a specific field is genuinely unclear, the instructions printed on the form come first and not stated governs where the two do not agree.

Formats available: PDF, across 1 pages and about 122 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.
Two states of the same page circulate, and the reason is worth knowing. In the fillable pdf, the boxes are real fields holding real data; in the printable pdf, the boxes are drawings. Where a record will cross components — as Department records regularly do — the typed version is the safer artifact. Each scan, each forwarding, each reproduction costs handwriting a little legibility, and the office that finally files the record is rarely the office that received it first.

Submission follows not stated and whatever local instruction supplements it. Make a copy before the original leaves. Department forms travel across organizational lines by design, and the administrative distance that makes them useful is the same distance that makes tracing a lost one difficult.
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.
Where a service form is cited in the same instruction, the two numbering systems should not be read across. DA numbering belongs to the Army and is administered by an Army proponent; DD numbering belongs to the Department and is administered by not stated or an equivalent Department office. The systems developed separately and were never harmonized, so identical digits in each identify two documents with nothing in common. The prefix, not the number, tells you which system you are in.
A form is downstream of the policy that requires it, and revision usually starts there: a directive is reissued, a collection requirement is altered, notice language is updated by statute. The form is republished as a consequence. Since none of that reaches individual users, an archived copy quietly becomes wrong, and verifying not stated each time you download is the whole remedy.
The role of this page is narrow and worth stating plainly. It makes a published Defense form available and explains its structure. It does not advise, does not interpret policy for your circumstances, and cannot indicate how any office will treat a completed copy — those judgments rest with the authorities that own the process. Direct such questions to not stated, to the administrative office that services you, or to the authority named in not stated.
