FOREWORD
The American Society for Mechanical Engineers (ASME) Committee Y14, Standards for Product Definition and Related Documentation Practices, formed Subcommittee 24, Types and Application of Engineering Drawings, in June 1973. The purpose was to prepare a standard defining accepted drawing types used to establish engineering requirements in the production and procurement of hardware.
The Subcommittee used Chapter 200 of the military standard MIL-STD-100, Engineering Drawing Practices (now cancelled), as a basis. They considered the types of engineering drawings most frequently used by business, industry, and government in the United States in their effort to serve the needs of these communities and assure consistency of application and interpretation.
A series of meetings were held to identify, select, and prepare proposed text and illustrations. At each stage, the Subcommittee considered which requirements were best suited for a national standard. Members of the Y14.24 Subcom- mittee represented a cross section of American industry and the Department of Defense (DoD). Liaison with specialized societies such as the National Defense Industrial Association (NDIA), Aerospace Industries Association (AIA), Electronic Industries Association (EIA) [now defunct; the standards brand is continued under the Electronic Components Industry Association (ECIA)], and the Society of Automotive Engineers (SAE) provided additional technical support.
Drawing definitions are intended to permit preparation by any suitable method (manual, computer-aided, photo- graphic, etc.); therefore, preparation techniques and methods of reproduction are not described.
The original edition of ASME Y14.24M was approved as an American National Standard by the American National Standards Institute (ANSI) on November 3, 1989. It was adopted and approved for use by the DoD on March 30, 1990. It was reaffirmed in 1996 without change.
Upon its release, the original edition of Y14.24M was referenced by the DoD as a replacement for the majority of Chapter 200 of MIL-STD-100E (released September 30, 1991). However, input from users of the DoD standard indicated that additional detail and clarification were needed to ensure understanding and application of the requirements when this Standard is invoked on government contracts.
Subcommittee 24 was reformed and began work on revising the Standard at a meeting in Garland, Texas held October 8 through 10, 1991. ASME Y14.24 was approved by ANSI as an American National Standard on June 24, 1999. It was reaffirmed in 2004 without change and published as ASME Y14.24-2012 on April 5, 2013. Work for the current revision was started in November 2012.
The following is a summary of the significant changes incorporated in this revision:
general drawing information was moved to its own clause
layout drawings were moved toward the end of the standard
definitions were added for the following:
altered item drawing (AID)
drawing graphic sheet
enterprise identifier (EID)
envelope drawing
NATO Commercial and Government Entity (NCAGE) Code
procurement specification
selected item drawing (SID)
source control drawing (SOCD)
vendor item control drawing (VICD)
the requirements for source control drawings were listed so users are no longer referred to other paragraphs
procurement control drawing types were moved to Nonmandatory Appendix B
source blocks for VICDs and SOCDs were revised
software item identification drawing type was introduced
new figures were added for the following:
monodetail 3D model annotation
exploded view assembly drawing
inseparable assembly 3D model annotation
