block 7

DoD Manual 5010.12-M has a thorough explanation of Block 7 codes (for example, “SS”, “DD”, “XX”). Use of a DD Form 250 is usually required for final data products intended to be baselines for government applications, such as engineering drawings, specifications, and TMs. The LT (Letter of Transmittal) code is used when a record of delivery is desired, but formal DD Form 250 inspection and acceptance is not required and the contracting office does not want to have a DD Form 250. However, “LT” and “NO” (no inspection or acceptance required) are not to be used when an inspection of the data is required (e.g., high cost data such as drawings, specifications, TDPs, or technical manuals).
