Treat DD Form 1218 as Department-level, which changes how you look for it. Title: DD Form 1218, Marshall Method - Computation of Properties of Asphalt Mixtures, December 1965. Function: Marshall Method - Computation of Properties of Asphalt Mixtures. Because the number carries DD rather than a service prefix, the same edition covers all military departments and the defense agencies at once. Nobody issues a Navy copy or an Air Force copy.
Requirement traces to not stated; the form belongs to not stated. Everything about schedule sits below that in local instruction, which is where to ask if a date matters.
Use not stated, status not stated. Older printings circulate widely and lose their currency Department-wide the moment a new edition issues.
The set is PDF. Size: 1 pages, about 200 fields.
All formats are free. One operational note: save the file locally and open it in a desktop reader. Browser-embedded viewers drop field properties and lose typed data without warning.

Edition check comes first, ahead of any entry. Compare the printed date to not stated and replace anything older. Department-level supersession is simultaneous across the services, so a superseded blank is not merely out of date locally; the office receiving it is already working from the new field structure whichever branch it belongs to.
Sequence matters. Identification precedes content, content precedes certification, because the lower half of a form is generally conditioned on the upper half.
Mark inapplicable items N/A rather than leaving white space. Use the date format the form specifies. This matters more on Department forms than on service forms: the record may be reviewed by personnel outside your branch who share none of your office conventions.
Privacy Act Statement first, personal entries second. It names the authority for the collection, what the data is for, who else routinely sees it, and whether you have to answer at all.
Sign last, in ink or with a credentialed digital signature. A typed name in a signature field certifies nothing. CAC-based signing is the usual electronic method where the receiving system supports it. Date the block immediately — unsigned and undated certifications account for a large share of returns.
Final pass, against the standing defect list: superseded edition, empty mandatory fields, handwriting illegible after scanning, non-conforming dates, missing signature or date. For anything ambiguous in a specific field, the form's own instructions come first and not stated controls where the two differ.
Send it as not stated or local guidance specifies. Save a copy. Cross-service and cross-agency routing is normal for Department forms, and a lost original outside your own organization is harder to chase down.
A number is a complete address in the DD series. Because the sequence is Department-level and not duplicated per service, there is nothing further to specify.
Where a procedure cites both a service form and a DD form, the two are unconnected. Service numbering answers to a service proponent, DD numbering to not stated or another Department office, and the two sequences were never aligned. Matching numbers mean nothing whatever.
Three drivers of revision: directive reissue, altered collection requirements, updated statutory notice text. No notification accompanies any of them, so download fresh and confirm not stated rather than reusing an archived file.
What is here is the blank form and a description of it. What is not here is legal guidance or any assurance about a particular filing — this page is not the issuing authority and does not speak for one. Those questions go to not stated, to your servicing administrative office, or to the authority identified in not stated.
