Defense Department form, series DD, number 1213. Full title: DD Form 1213, Unconfined Compression Test, August 1957. Function: Compression Test, Unconfined. 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.
Users include uniformed members of any branch, DoD civilian employees, contractor personnel where authorized, and the administrative staff who process the completed record.
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.
Available formats: PDF. The form runs 1 pages and contains approximately 200 fillable fields.
The pdf is the primary distribution format. A fillable pdf accepts typed entries in defined field boxes and stores them in the file; a printable pdf is a flat image of the blank, meant for pen entry after printing. The distinction matters for legibility and for records that pass between offices.

Completion runs in the order printed on the page: identifying data at the head, the body of the entry next, certification at the foot. Header data frequently governs what belongs in the fields below it.
Verify the edition date against not stated before entry. Department-level revisions replace the blank across every service simultaneously, so an old copy in a desk drawer may no longer correspond to current field numbering.
Field-level instructions appear on the form itself and in not stated. The directive is the controlling text.
After completion, the copy goes to the office designated by not stated or by local procedure. Retention of a personal copy is ordinary practice and costs nothing.
Related documents are located by series and number. DD forms sit in a single Department-wide sequence, so a form referenced inside DD Form 1213 is normally found by its number alone, without regard to service.
A DD number and a DA number may appear in the same instruction without being related. DA forms belong to the Army alone; DD forms belong to the Department and are administered at Department level. The sequences are independent.
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.
