Drawing Data Elements
Drawing Data Elements

A complete listing of various Government and approved Non-Government documents used in the preparation of engineering drawings.

Documents listed herein are applicable only as specified in the contract or DRAWING REQUIREMENTS MANUAL (DRM) sections.

Scope

Purpose

This section establishes the essential requirements for the preparation and revisions of engineering drawings, requirements for drawing disclosure, hard copy drafting requirements, digital data files (2D and 3D) and associated lists prepared under the requirements of ASME Y14.100-2004. It is essential that ASME Y14.100 be used in close conjunction with ASME Y14.24, ASME Y14.34M and ASME Y14.35M for establishing the basic requirements for commercial applications. Department of Defense (DoD) needs and requirements often extend beyond commercial applications. To invoke these additional DoD requirements, drawings must be part of a Technical Data Package (TDP) per MIL-DTL-31000. Under the requirements of MIL-DTL-31000, drawings, models, and related documentation are required to adhere to default and selected specifications and standards. TDPs may be classified as Type 2D or Type 3D, and are composed of one or more TDP elements and related TDP Data Management Products. These requirements support all Departments and Agencies of the Department of Defense’s Defense's policy of acquiring only those engineering drawings and associated lists that are needed.

Note: "Drawing Categories" and "Forms", formerly defined in MIL-D-1000 and drawing "LEVELS" formerly defined in DOD-D-1000B no longer apply.

Language

Unless otherwise specified in the contract or by an international agreement, drawings and associated documents shall be in the English language.

Selective Application

Selection of the TDP elements and the TDP data management products to make up a TDP must be based on the Government’s needs for technical data required to support the acquisition and life cycle support strategies for the product being documented. The Government’s need for technical data varies greatly from program to program. It may range from conceptual design data for concept evaluation to a complete set of detailed design data for reprocurement of items essentially identical to the original item.

Tailoring Implementation

All contractual requirements, government or non-government herein are subject to tailoring. These requirements, as well as the requirements of specific TDP elements and TDP data management products selected for inclusion in the TDP, should be tailored by the Government prior to release of the solicitation. This includes the requirements stated in data item descriptions, Government or non-Government standards and requirements for the media and methods of delivery. Furthermore, a contractor may recommend additional tailoring of TDP requirements as specified in a solicitation or contract using the guideline of MIL-HDBK-248

Classification

This SECTION covers the following TDP elements and TDP data management products.

TDP elements for Drawings

(See PARAGRAPH 2.5) When MIL-DTL-31000 is applied to the contract or Purchase Order (PO) in order to obtain data, the referenced Data Item Descriptions (DIDs) must be listed as applicable on the Contract Data Requirements List (CDRL) (DD Form 1423). See APPENDIX A FIGURE 2A-9.

This requirement is exempt when DOD FAR Supplement 27.475-1 is cited.

  • Conceptual design drawings. (Ref: DI-SESS-81001C)
  • Developmental design drawings and associated lists. (Ref: DI-SESS-81002D)
  • Product drawings and associated lists. (Ref: DI-SESS-81000C)
  • Commercial drawings and associated lists. (Ref: DI-SESS-81003C)
  • Special inspection equipment (SIE) drawings and associated lists. (Ref: DI-SESS-81004C)
  • Special tooling (ST) drawings and associated lists. (Ref: DI-SESS-81008C)
  • Specifications (Ref: MIL-STD-961 and IEEE 12207.0, 12207.1, and 12207.2)
  • Packaging (Ref: MIL-STD-2073-1)

TDP data management products

(See PARAGRAPH 2.5.5)

  • Source control drawing approval request. (Ref: DI-SESS-81010C)
  • Drawing number assignment. (Ref: DI-SESS-81011C)
  • Proposed critical manufacturing process description. (Ref: DI-SESS-81012C)

Reference to the Application of Non-Government Standards (NGSs)

ASME Y14.100-2004 is the mandatory requirements document for engineering drawing practices. This move from MIL-STD-100 to ASME Y14.100 was part of Acquisition Reform Movement described in Non-Mandatory Appendix C at the end of SECTION 2 of the DRM. With the elimination of the waiver requirement for using MIL-SPECS and MIL-STDS discussed in Preface 1, MIL-SPECS and MIL-STDS may be used if a NGS is not available or fails to support basic document preparation requirements. The user may also detail the needed engineering drawing practice directly in the Statement of Work (SOW), Contract or Purchase Order (PO) if desired. Historically, canceled MIL-STD-100G and related applicable specifications were used to provide military requirements in excess of commercial applications. When MIL-STD-100G was canceled, those applicable military specifications and standards were moved to Appendices B thru E of ASME Y14.100-2004. To invoke these Appendices in a Statement of Work (SOW), contract or purchase order requires “tailoring” as described in Appendix “A” of ASME Y14.100-2004. The use of MIL-STD-100G will continue on current and on-going contracts. Switching from MIL-STD-100 to ASME Y14.100 will not be required unless economically feasible or otherwise justified.

Reference to the Application of the Appendices A thru E of ASME Y14.100

MIL-STD-100 has largely been replaced by Non-Government Standards (NGS) ASME Y14.100 including Appendices A thru E. Reasons for invoking the appendices in entirety, or in part, are listed as follows:

  • Contains only Government unique requirements and is restricted for use to those DoD activities.
  • Have DoD peculiar logistics requirements.
  • Have specific & fully justifiable requirement for TDP delivery & maintenance control by a DoD design activity.
  • Essential that drawings indicate a Government design activity CAGE Code.

Rule Regarding the Use of the Appendices B thru E of ASME Y14.100

ASME Y14.100 addresses engineering drawing practices in commercial applications or where DoD design requirements need not be under the change control authority of a DoD activity. All referenced documents and detail associated with basic drawing practices are contained in ASME Y14.100. Accordingly, the Appendices B thru E of ASME Y14.100 and appropriate revision as applicable, must always be used in conjunction with ASME Y14.100. In addition, since requirements for broad areas, of subject material are now addressed by individual ASME standards, ASME Y14.100 must be used in conjunction with:

  • ASME Y14.24 Types and Application of Engineering Drawings
  • ASME Y14.34M Associated Lists
  • ASME Y14.35M Revision to Drawings and Associated Lists

Tailoring Guidance for Checking Compliance with Contractual Requirements

To ensure proper application of ASME Y14.100 any tailoring provided by Appendix “A” including the Appendices B thru E must also be consistent with MIL-DTL-31000, TDP Option Selection Worksheets. Tailoring must exclude unnecessary requirements for invitations for bids, request for proposals and Contract Data Requirements Lists (CDRLs). See APPENDIX A FIGURE 2A-9. It is essential that the numerous referenced documents be reviewed to exclude unnecessary requirements in accordance with the program or end item requirements by tailoring. The following procedures must be reviewed to determine if a requirement is not a current operational procedure and an alternate procedure would be more economical in complying with the contract in the acquisition of documents. (See TAILORING that follows.)

DEFINITIONS

Associated Lists

An associated list is a tabulation of engineering information on a drawing or set of drawings pertinent to an item depicted in a Technical Data Package (TDP). (Ref: ASME Y14.34M)

Commercial And Government Entity (CAGE) Code

A five-character code listed in Cataloging Handbook H4/H8 , Commercial and Government Entity (CAGE) Code, which is assigned to commercial and Government activities that manufacture or develop items, or provide services or supplies for the Government. When used with a drawing number or part number, the CAGE Code designates the design activity from whose series the drawing or part number is assigned, The CAGE Code was previous called manufacturer’s code, code identification number or Federal Supply Code for Manufacturers (FSCM).

Commercial Drawings

Drawings prepared by a commercial design activity following its drawing format and standards for the development and manufacture of the product without government expense.

Commercial Inspection Equipment (CIE)

Standard equipment of commercial design that has not been modified and has universal application without limitations to a specific commodity, item, or component which is advertised or cataloged as being available to the trade or to the public on an unrestricted basis and is used to determine compliance to Technical Data Package (TDP) requirements.

Commercial Item Description (CID)

A simplified product description or specification that describes by salient functional or performance characteristics the available and acceptable commercial products that will satisfy the Government's needs. CIDs are prepared under guidelines issued by the General Services Administration’s Federal Supply Service (GSA-FSS), and are listed in the ASSIST DATABASE.

Commercial Product

A product, material, component, subsystem or system sold or traded to the general public in the course of normal business operations at prices based on established catalog or market prices.

Company Standard

A company standard is a document that establishes uniform and preferred practices and techniques, and sets limitations for engineering and technical applications for items, materials, processes, methods, design and engineering practices unique to that company. (NOTE: Company standards are not considered to be non-Government standards.)

Competent Manufacturer

A manufacturer that has demonstrated the capability to produce similar products at the same state of the art in the same or similar lines of technology.

Conceptual Design Drawings

Drawings used to verify preliminary design and engineering. They are one of the factors used to determine that the technology is feasible and that the design concept has utility against stated military requirements in order to reduce technical uncertainty. These drawings may evolve into developmental design drawings.

Critical Manufacturing Process

A process is critical if it is the only known method which will result in the production of an acceptable item.

Design Maturity

The extent to which the final design or configuration of an item has been defined by the engineering process. For example, the design of a sheet metal cover having holes in its mounting hole pattern fully dimensioned and toleranced for final size, location and orientation would be considered to be more mature than the design of a similar cover having its mounting hole pattern defined as “Drill at Assembly”.

Detail Design Data

Technical data that describes the physical configuration and performance characteristics of an item or component in sufficient detail to ensure that an item or component produced in accordance with the technical data will be essentially identical to the original item or component. (DFARS, Part 227).

Detail Specification

A specification that specifies design requirements, such as material to be used, how a requirement is to be achieved, or how an item is to be fabricated or constructed. A specification that contains both performance and detailed requirements is still considered a detail specification. (Ref: MIL-STD-961)

Design Disclosure Information

The complete description, including all specifications, standards, drawings, lists and critical processes necessary to manufacture an item without recourse to additional design or engineering services.

Design Drawings

Drawings of a conceptual or developmental nature prepared for use in evaluating proposed technology, design concept, design approach, and fabrication of hardware for test or experimentation in response to stated requirements. Although ideally design drawings would evolve to product drawings, the requirements of ASME Y14.100 may not be applicable.

Developmental Design Drawings

Drawings used to fabricate developmental hardware for test or experimentation of a prototype or experimental material and define a specific design approach. In addition, the data shall be suitable for evaluation of the inherent ability of the design to attain the required performance. These drawings may evolve into product drawings.

Drawing Form

A sheet of drafting material displaying the basic format features such as title block, general tolerance blocks and margins in accordance with ASME Y14.1 or ASME Y14.1M.

Drawing Format

The arrangement and organization of information within a drawing, including the size and arrangement of blocks, notes, lists, revisions, the use of optional or supplemental blocks, etc.

End Product

An end product is an item, such as an individual part or assembly, in its final or completed state. (ASME Y14.24). Also known as an end item.

Inspection Equipment

Equipment such as dimensional gauges, measurement equipment, test fixtures, electronic and physical test equipment, and other test equipment that is used for examination, evaluation and test of a product to determine its conformance to drawings, specifications, or other requirement documents.

Item (Item of Supply)

An end item, component, or part, records for which are maintained for stock, storage, and issuance in support of military requirements. (Examples of items of supply are airplanes, ships, trucks, radar, radar components, hand tools, fasteners, uniforms, and food.)

Non-Government Standard (NGS)

A Standardization document developed by a private sector association, organization, or technical society which plans, develops, establishes, or coordinates standards, specifications, handbooks, or related documents. Company standards are not considered as non-Government standardization documents.

Performance Specification

A specification that states requirements in terms of desired results with criteria for verifying compliance, but without stating the methods for achieving the required results. A performance specification defines the functional requirements for the item, the environment in which it must operate and interface and interchangeability characteristics. (Ref: MIL-STD-961)

Physical Configuration Audit (PCA)

The formal examination of the “as built” configuration of an item against its technical documentation to establish or verify the configuration item’s product baseline.

Product Drawings

Engineering drawings which provide the design, engineering, manufacturing and quality support information necessary to permit a competent manufacturer to produce an interchangeable item which duplicates the physical and performance characteristics of the original design without additional design engineering or recourse to the design activity.

Reference Documents

Documents that contain required engineering data that is too voluminous to be placed upon the drawing or are applicable to more than one item, process, or material.

Shipping List

A shipping list is a tabulation of all documents included in a delivery or shipment.

Special Test Equipment (STE) (also called Special Inspection Equipment (SIE))

Either single or multipurpose integrated test units engineered, designed, fabricated, or modified to accomplish special purpose testing in performing a contract. It consists of items or assemblies of equipment that are interconnected and interdependent so as to become a new functional entity for testing purposes (FAR 45.101).

Special Tooling

Unique tooling which is mandatory to the manufacture of an acceptable item. It differs from tooling designed to increase manufacturing efficiency in that the use of the special tool imparts some characteristic to the item which is necessary for satisfactory performance and cannot be duplicated through other generally available manufacturing methods. Examples of special tooling would be jigs, dies, fixtures, molds, patterns and other equipment or manufacturing aids that absolutely must be used to produce a satisfactory item.

Specifications

A specification is a document prepared specifically to support acquisition which clearly and accurately describes the essential technical requirements for purchasing material. Procedures necessary to determine that the requirements for purchased items, materials, and processes covered by the specifications have been met shall also be included. (The term “specification” is also used to describe the requirements specified on a drawing or other contractually binding document, such as the material, dimensions and tolerances, surface texture, finish, heat treatment, physical, and other requirements.)

Standard Microcircuit Drawing

A Government unique drawing type used to define the physical and performance characteristics of commercial microcircuits in Federal Supply Class 5962 used in military applications.

Standardization Directory (SD-1)

A document issued quarterly that identifies standardization responsibility assignments by Federal Supply Classes and Standardization Areas and provides the addresses of the military offices, federal civil agencies, and non-Government standards bodies participating in the Defense Standardization and Specification Program (DSSP).

Standardization Document

  1. Exploratory Development (bread board)
  2. Advanced Development (brass board)
  3. Engineering Development (service test)
  4. Production (prototype)
  5. Production

Technical Data

Recorded information, regardless of the form or method of recording, of a scientific or technical nature (including computer software documentation). The term does not include computer software or data incidental to contract administration, such as financial or management information. (DFARS Part 227).

Technical Data Package (TDP)

The technical description of an item adequate for supporting an acquisition strategy, production, engineering, and logistic support. The description defines the required design configuration and procedures to assure adequacy of item performance. It consists of all applicable technical data such as drawings, models, associated lists, specifications, standards, performance requirements, quality assurance provisions, and packaging details.

Technical Data Package Document
