DD Form 1220 — DD Form 1220, Concrete Mixture Design Data, August 1957

Concrete Mixture Design Data

Consider what a Department-level form is for. DD Form 1220 — DD Form 1220, Concrete Mixture Design Data, August 1957 — was established to Concrete Mixture Design Data, and it was placed in the DD sequence because the underlying transaction occurs throughout the Defense establishment in substantially the same shape. Standardizing the record was cheaper and more reliable than letting six services each design their own.

The practical effect of Department-level issue is interoperability. not stated establishes the requirement across the Defense enterprise; not stated keeps the document current for all of it. No service maintains its own variant, which means a completed record travels between components — service to agency, agency to joint command — and arrives in a format the receiving office already knows how to read.

Current edition: not stated, status not stated. Understand why that date is worth attention here. When the Department reissues a form, the replacement takes effect across every component simultaneously, so an older copy is not merely locally out of date — it is out of date in every office that might receive it.

The sequence printed on the form is the sequence in which a reviewer will read it, and the two should agree. Header data frames every entry below it; the substantive fields depend on that frame; the certification stands at the end because its whole function is to vouch for what came before. Entries made out of sequence commonly contradict entries made earlier.

Before the first entry, compare the date printed on the form face with not stated. This is not bureaucratic fussiness. Editions change field numbering, and a receiving office working from the current layout may look for information where your copy does not put it. On a Department form the exposure is wider than usual: your record may be reviewed by an office in another service entirely, one with no reason to remember what the previous edition looked like.

Leave nothing empty. Where an item genuinely does not apply, N/A is the correct entry, because the record must distinguish between a question that was answered in the negative and a question that was never reached. An empty box carries no information about which happened. Date fields deserve particular care on a Department form, since the reviewer may write dates by a convention different from yours; use the format the form itself specifies.

Understand what the Privacy Act Statement is doing on the page. It exists because collecting personal data from an individual triggers a duty to explain the collection: under what authority, for what purpose, to whom the information may routinely go, and whether you are obliged to answer. That explanation precedes the fields for the obvious reason — afterwards it is merely a notice, beforehand it is a basis for deciding.

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.

Xfdl appears in the set for reasons of institutional inertia rather than preference. It is the IBM Lotus Forms format, once the Department's electronic forms standard and deployed widely enough that it outlived the decision to move on. IBM Lotus Forms Viewer or an equivalent client opens it; a pdf application will not.

Every format is free, as published government documents are. A note on tools, though — the interactive field layer that makes a fillable pdf useful is precisely the part browser viewers handle least reliably. Save the file, open it in a full pdf reader, and the fields behave as the form's designer intended.

The completed form goes to the office named in not stated or in local implementing procedure, and it is worth keeping a copy before it goes. On a Department form the destination is frequently outside your own chain — another service, a defense agency, a joint staff — and recovering a document that has crossed an organizational boundary is a slower business than retrieving one from a file down the hall.

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.

Procedures that touch both Department and service processes will cite forms from both sequences, and the coincidence of numbers between them is exactly that — coincidence. An Army proponent maintains the DA series for the Army; not stated or another Department office maintains the DD series for the whole Department. Two independent registries, two independent numbering runs, no correspondence at any value.

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.

What you have here is the document and a description of it, which is a different thing from guidance. This page is not an organ of the Department, gives no legal or procedural advice, and makes no representation about the outcome of any filing; the offices that administer the requirement are the only ones positioned to answer that. Applicability, eligibility and procedural questions belong to not stated, to your servicing personnel office, or to the office designated in not stated.
