Use & Relationship

Special Tooling Engineering Design Data and Associated Lists provide the data required for the limited production of special tooling which duplicates the physical and performance characteristics of the original special tooling. This Data Item Description (DID) contains the format and content preparation instructions for Special Tooling Engineering Design Data and Associated Lists resulting from the work task described by 5.4.3 of MIL-STD-31000. This DID is applicable to acquisition of military systems, equipment, and components which require the use of special tooling to achieve the engineering requirements of the item.

Preparation Instructions

1Reference documents.The applicable issue of the documents cited herein, including their approval dates and dates of any applicable amendments, notices, and revisions, shall be as specified in the contract.

2General.Special Tooling Engineering Design Data and Associated Lists shall meet the requirements of MIL-STD-31000 and shall be in accordance with, ASME Y14.100, or, if applicable, ASME Y14.100 and Appendices B through E, as required, ASME Y14.34, and ASME Y14.41.

3Format.Special Tooling Engineering Design Data and Associated Lists shall be in contractor or Government format or as specified in the contract or purchase order.

4Content.Special Tooling Engineering Design Data and Associated Lists shall provide the design disclosure information necessary to permit the manufacture of tooling that duplicates the functions of the original Special Tooling. Special Tooling Engineering Design Data and Associated Lists shall provide:

4.1Details of processes which are not published or generally available to industry, when these processes are mandatory to achieving the engineering requirements of the tooling.

4.2Performance ratings and tolerances.

4.3Dimensions and tolerances.

4.4Critical manufacturing processes and assembly sequences.

4.5Toleranced input and output characteristics.

4.6Diagrams.

4.7Mechanical and electrical connections.

4.8Physical characteristics, including form and finish requirements.

4.9Details of material identification, including heat treatment and protective coatings.

4.10Calibration information.

4.11Environmental requirements.

4.12Reliability requirements.

4.13Maintainability requirements.

5Selection of engineering design data.The types of engineering design data and associated lists to be prepared shall be selected from ASME Y14.24 and ASME Y14.34. The applicable TDP Option Selection Worksheet incorporated in the contract or purchase order will specify whether the contractor or the Government is responsible for selecting the types of engineering design data and associated lists to be prepared.

6CAGE Code and document numbers.Special Tooling Engineering Design Data and Associated Lists shall be identified with the contractor's CAGE Code and contractor document numbers or with a Government CAGE Code and Government document numbers as specified in the applicable TDP Option Selection Worksheet incorporated in the contract.

7Control drawings.Vendor items used in the Special Tooling without alteration, selection, or source qualification shall be identified on Special Tooling Drawings and lists by the manufacturer's CAGE Code and part or identifying number. Vendor Item Control Drawings are not required for vendor items. When vendor items must be altered, selected, or required source qualification prior to use in the ST, they shall be documented on Altered Item, Selected Item, or Source Control Drawings in accordance with ASME Y14.100 and ASME Y14.24.
