2.1 SCOPE

2.1.1 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. 

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

2.1.1.2 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 procurement of items essentially identical to the original item.

2.1.1.3 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

2.1.2 Classification.  This SECTION 2 covers the following TDP elements and TDP data management products.

2.1.2.1 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.  

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

2.1.2.2  TDP data management products.  (See PARAGRAPH 2.5.5) 

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

2.1.3 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. 

2.1.4 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: 

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

2.1.4.1 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

2.1.5  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.)
