DD Form 1795 occupies a particular place in Defense recordkeeping. Its title is DD Form 1795, Combined Mechanical Analysis (Sedimentation Test), February 1971, and it exists to Combined Mechanical Analysis (Sedimentation Test). What the DD prefix records is an administrative judgment made long before your copy was printed: this transaction was determined to be common to the whole Department rather than peculiar to one service, and so the documentation of it was standardized at Department level.
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.
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.
The form is laid out top to bottom in a sequence that reflects how the record will be read, not merely how it was drawn. Identification comes first because everything below it is understood in relation to a named person, unit or transaction; substantive entries follow; certification closes the document because certification attests to what precedes it. Filling out of order tends to produce internal inconsistencies — an entry that made sense before the header was settled and does not afterward.
Check the edition date before you type anything, against not stated. Old blanks accumulate in shared drives for years, and the cost of one is not obvious until a reviewer cannot find a field. Because DD forms are revised centrally and replaced across the Department in a single action, there is no component still tolerating the old layout as a local practice.
Every field takes an entry, N/A included. The reason is evidentiary rather than clerical: a completed record is supposed to show what was asked and what was answered, and blank space records neither. On dates, follow the format printed beside the field. Conventions vary between components, and a joint document is read by people who do not share your habits.
Where the form collects personal identifiers, a Privacy Act Statement accompanies it, and its placement is meaningful. The statute requires disclosure at the point of collection — authority, purpose, routine uses, and the consequence of declining — so that the person supplying the information does so knowing what becomes of it. Reading it after you have filled the fields inverts the arrangement entirely.
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.
Every item on the standing defect list undermines the record in the same way — it leaves a question the file cannot answer later. Obsolete edition, empty mandatory boxes, illegible scanned handwriting, non-conforming dates, missing signature or date. Unclear entries are resolved from the printed instructions first and from not stated where the two texts diverge.
Download the form
The set published here is PDF, covering 1 pages with roughly 116 fields. More than one format survives because the Department serves users under very different conditions, from a desk with current software to a location where a printer is the only reliable output.
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.
Editions change for reasons that originate above the form itself. The prescribing directive is reissued and the form follows; the information the Department needs to collect changes and the fields change with it; the statutory notice language is amended and every form carrying that notice is republished. None of these events announces itself to the person who downloaded a copy last year, which is why confirming not stated at the moment of download is the only reliable check available to you.
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.
