FOREWORD

This Standard establishes engineering drawing practices and ties together the engineering drawing and related documentation practices in the Y14 series. It is not the intent of this Standard to be a stand-alone document for the purpose of addressing basic practices. An accurate perception of engineering drawing practices is derived by treating ASME Y14.100, ASME Y14.24, ASME Y14.34M, and ASME Y14.35M as a composite set.

This Standard is a revision of ASME Y14.100-2000, Engineering Drawing Practices. The revision of this Standard was initiated after the official release of ASME Y14.100M-2000. The initial attempt to convert the DoD drawing practices standard, MIL-STD-100, to a nongovernment standard resulted in two drawing practices standards: ASME Y14.100M-1998, which consisted of basic practices common to DoD and industry, and MIL-STD-100G, which consisted of those practices and requirements unique to DoD. The impact on the community was that judgments on when to use which standard as a stand-alone or in combination were causing a good deal of confusion. Accordingly, the realization of the problems presented by the existence of two basic drawing practices standards is the basis for the issue of this revision. The consensus was that one standard was needed. To accomplish this, this Standard contains appendices that may be invoked and tailored by DoD, thereby making possible the cancellation of MIL-STD-100.

Changes contained in this revision are intended to improve standardization and harmonize practices and methodology between industry and government. The following is a summary of the significant differences between ASME Y14.100-2000 and this revision:

1. Section 3 — added the reference to ASME Y14.34 to the definition for associated lists;

2. Section 3 — added a definition for Notes (flag, general, local);

3. Para. 6.5 — deleted paras. 6.5 and 6.5.1 and replaced with the following new paras.:

   1. 6.5, Drawing Identification and Ownership

   2. 6.5.1, Drawing Identification

   3. 6.5.1.1, Design Activity Identification

   4. 6.5.2, Drawing Ownership, Current or Original Design Activity

   5. 6.5.2.1, Transferring Design Responsibility to Another Activity

4. Added a new Fig. 1, Drawing Notations Indicating a Transfer of Design Responsibility;

5. Renumbered remaining figures appropriately;

6. Added new para. 7.6.1 and renumbered remaining para. 7.6.1 to 7.6.2;

7. Para. 7.11, deleted reference to Fig. 4;

8. Fig. 2, deleted two of the ESD Symbols leaving only the hand ESD Symbol;

9. Deleted old Fig. 4, Location of CAD-Generated Drawing Note;

10. Para. D9.8, corrected 15-character PIN to 32-character PIN; and

11. Para. D9.9.1, Parent or Corporate CAGE Code — clarified the sentence to indicate that when a drawing remains within the jurisdiction of a corporate or parent entity, there is no requirement for drawing revision to indicate design activity transfer.

It is not the intent of this Standard to prevent individual organizations from designing specific drawing practices that meet their individual needs but rather to provide common engineering delineation standards to aid the increasing interchange of drawings between industry, government, and other users. It is well recognized that individual companies have many detailed requirements for their specific method of operation. Consequently, the minimum requirements set forth in this Standard will provide them flexibility in implementation. The appendices are intended for use by other than strictly commercial organizations, such as DoD; however, nothing prevents commercial organizations from using the appendices and tailoring them as necessary to meet their own needs.

The successful revision of this Standard is attributed to the subcommittee members and their respective companies and the department and agencies of the U.S. government.

Suggestions for improvement of this Standard are welcome and should be sent to The American Society of Mechanical Engineers; Attention: Secretary, Y14 Main Committee; Three Park Avenue, New York, NY 10016-5990.

This revision was approved as an American National Standard on September 9, 2004.

ASME Y14.100-2004

ENGINEERING DRAWING PRACTICES

1. GENERAL

   
   

   1. Scope

      This Standard establishes the essential requirements and reference documents applicable to the preparation and revision of engineering drawings and associated lists. It is essential that this Standard be used in close conjunction with ASME Y14.24, ASME Y14.34M, and ASME Y14.35M.

      
      

   2. Application

      Application of this Standard may necessitate tailoring to exclude unnecessary requirements. A tailoring guide, Nonmandatory Appendix A, has been included for that purpose.

      
      

   3. Figures

      The figures in this Standard are intended only as illus- trations to aid the user in understanding the practices described in the text. In some cases, figures show a level of detail as needed for emphasis. In other cases, figures are incomplete to illustrate a concept or facet thereof. The absence of figures has no bearing on the applicability of the stated requirement or practice.

      
      

   4. Notes

      Notes depicted in this Standard in capital letters are intended to reflect actual drawing entries. Notes in low- ercase letters are to be considered supporting data to the contents of this Standard and are, therefore, not intended for literal entry on drawings.
