Defense Department form, series DD, number 1209. Full title: DD Form 1209, Liquid- and Plastic-Limits Determination, December 1999. Function: Liquid- and Plastic-Limits Determination. Edition in force: not stated. Publisher status: not stated.
Governing directive: not stated. Responsible office: not stated. The DD designation signals joint scope — all military departments, combatant commands and defense agencies draw on a single edition of the document.
The form reaches military personnel across the services, civilian employees of the Department, and the personnel and records specialists who receive it.
When the form is filed is a matter of not stated and local instruction. The description here covers the document itself and how to obtain a copy.
Formats offered: PDF. Length: 1 pages. Fillable field count: roughly 117.
Pdf serves as the base format. In the fillable variant, each box is an interactive field that holds typed text inside the document. In the flat printable variant, no fields exist — the page prints as a blank to be completed by hand. Typed entries survive transmission; handwriting does not always survive scanning.
The xfdl release corresponds to IBM Lotus Forms. This format carried Department-wide form distribution for years and opens only in IBM Lotus Forms Viewer or a compatible client, not in a pdf reader.
All formats download free of charge. Pdf files open in any modern reader; interactive fields behave most predictably in a desktop application, less so in browser viewers.

The document is filled from the top down. Identification precedes substance, substance precedes certification. Fields lower on the page are commonly keyed to entries made above them.
The current edition is not stated. Superseded editions of DD forms are frequently rejected at the receiving office, since Department-wide forms change centrally and older layouts lose their field correspondence. Edition date appears in the lower corner of the printed blank.
The signature block takes an actual signature. On paper this means ink; electronically it means a credentialed digital signature, commonly CAC-based. Typed text in a signature field satisfies neither.
Privacy Act notice: DD forms that collect personal data carry a Privacy Act Statement stating the authority for collection, the principal purpose, routine uses and whether disclosure is voluntary or mandatory. The statement is part of the form and should be read before entry, not after.
Frequent defects: obsolete edition, unfilled required boxes, handwriting that fails on reproduction, non-conforming date format, and certification without a corresponding date.
Guidance for specific entries sits on the form face and in not stated; the directive is authoritative where the two do not agree.
Once executed, routing follows not stated and the submitting organization's own instruction. Keeping a copy is standard.
Associated forms are traced by number within the series. Because the DD sequence is common to all military departments, no service qualifier is needed to identify a referenced form.
Some procedures pair a DD form with a service form. The two numbering systems are separate — service forms answer to a service proponent, DD forms to not stated or another Department office — and a matching number in each system means nothing.
Editions change because the underlying directive changes, because collection requirements are revised, or because Privacy Act language is updated. Checking the edition date at the point of download is the practical response.
This page distributes a published Department of Defense document and describes it. It is not a source of legal advice and makes no representation about acceptance of any completed form. Questions of applicability, eligibility or procedure belong to not stated, the servicing personnel office, or the office named in not stated.
