FOREWORD

Subcommittee 38, Abbreviations, was formed in May 1995, and is a Subcommittee of the ASMEStandards Committee Y14, Engineering Drawing and Related Documentation Practices. TheSubcommittee is charged with the responsibility of compiling and maintaining a listing of abbrevi-ations and acronyms for use on engineering drawings and related documents.

ASME Y1.1 was revised and redesignated as ASME Y14.38. This Standard is based on ASME Y1.1and MIL-STD-12.

This revision of ASME Y14.38 incorporates the ASME Y14.38a-2002 addenda and commentsreceived since the release of the ASME Y14.38-1999 revision. No abbreviations or acronyms wereeliminated; however, one abbreviation was changed: SME was “standard military drawing,” andit has changed to “standard microcircuit drawing.”

The successful completion of this Standard is attributed to the subcommittee members, contrib-uting guests, and the departments and agencies of the U.S. Government.

Suggestions for the improvement of this Standard are welcome. They should be sent to TheAmerican Society of Mechanical Engineers; Attn.: Secretary, Y14 Main Committee, Three ParkAvenue, New York, NY 10016-5990.

This revision was approved as an American National Standard on September 12, 2007.

ASME Y14.38-2007

ABBREVIATIONS AND ACRONYMS FOR USE ON DRAWINGSAND RELATED DOCUMENTS

1 SCOPE AND PURPOSE

1.1 Scope

The abbreviations and acronyms, hereinafter referredto as “abbreviations,” listed in this Standard are usedon engineering drawings and related documentation.

1.2 Purpose

The intent of this Standard is to allow the use ofapproved abbreviations in lieu of the use of completewords or terminology. Abbreviations defined by thisStandard need not be additionally defined by the usingdrawing or related document. It is not the intent of thisStandard to include abbreviations defined or establishedin other standards such as those for scientific termsand notations. However, an exception is made for thoseabbreviations that have widespread use and recognition,for example, AM for amplitude modulation, and FM forfrequency modulation (radio).

1.3 Abbreviations and Letter Symbols

Since abbreviations are conventional representationsof words or names in a particular language, they maybe different in different languages. A symbol, on theother hand, represents a quantity or a unit (not its name)and is therefore independent of language. Because ofthis, the use of letter symbols is preferred over abbrevia-tions for unit or quantity terms. While letter symbolsmay be used wherever abbreviations were formerlyused, abbreviations are never to be used whenever amathematical operation sign is involved, such as theequality sign (p) or the division sign (/).

1.4 Abbreviation Lists Format

Abbreviations shown in the “Drawings” column pro-vide the form for use on drawings and documents pro-duced with upper case characters. Abbreviations in the“Text” column provide the form for documents pro-duced with lower case characters. Where upper caseabbreviations are shown in the “Text” column, they area continuation of prior usage and are generally for majorsystems or are recognized as having significant applica-tions when used in text. Bracketed modifiers may appearwith certain terms indicating alternate technology-specific applications for that term.

1

2 WHERE AND HOW ABBREVIATIONS SHOULD BEUSED

2.1 Where to Use Abbreviations

Abbreviations are to be used only where necessary tosave time and space. Even though this Standard estab-lishes abbreviations for many terms, extreme care shouldbe exercised in their use. Since they may have to beinterpreted by people of varying backgrounds, abbrevia-tions should be used only where their meaning isunquestionably clear to the intended reader. Where thereis doubt that the reader will understand the meaning,spell out the word or complete phrase where first used,followed by the abbreviation or acronym in parentheses.When in doubt, spell it out.

2.2 Duplicate Abbreviations

The same abbreviation is included in this Standardfor several different terms due to established practice.Care should be exercised to assure that the proper mean-ing will be interpreted when using such abbreviations.

3 BASIC PRINCIPLES

3.1 Abbreviations for Acronyms

Sections 5 and 6 include some acronyms for com-pound terms as well as abbreviations for the acronyms.Some examples are: “radar” for “radio detection andranging” and “rdr” for “radar”; “selsyn” for “self-syn-chronous” and “sels” for “selsyn.”

3.2 Punctuation

An abbreviation spelling a whole word shouldinclude a period if the abbreviation could bemisinterpreted.

3.3 Spacing

Spaces shall not be inserted within an abbreviation.

3.4 Capitalization

Abbreviations included in the “Drawings” column ofsection 5, provide the form for use on drawings anddocuments produced in upper case characters. Theabbreviations in the “Text” column provide the formrequired for lower case characters. However, theseabbreviations may be capitalized when required for



--```,,,,,,```,,`,`,```,`,`,``,-`-`,,`,,`,`,,`---

ASME Y14.38-2007

emphasis. Abbreviations that are capitalized in the“Text” column are a continuation of prior usage andin general are abbreviations for major systems or arerecognized as having significant application when usedin text. Abbreviations are not listed in the column formany short words. If space limitations make it necessaryto abbreviate such terms, the abbreviation that appearsin the “Drawings” column shall be used except for sub-stitution of lower case letters.

3.5 Syntactical Endings

Unless otherwise indicated, the same abbreviationsshall be used for all tenses, participle endings, the pos-sessive case, the singular and plural, and the noun andmodifying forms of a term. Some examples are: “bm”for beam and beams; “calc” for calculate, calculated,calculating, and calculation.

3.6 Word Combinations

An abbreviation of a word combination shall not beseparated for use individually; e.g., the abbreviation forstainless steel “sst” is not to be split to use “s” for stain-less and “stl” for steel. Individual abbreviations may becombined when necessary if there is no abbreviationlisted for the combination; e.g., the abbreviation for aver-age “avg” and temperature “temp” can be combined as“avg temp” for average temperature.

3.7 Combining Forms

Where two abbreviations are listed for the same wordsuch as “cath” for “cathode” and “c” for “cathode,” asin “cathode ray tube, (comb form),” the first abbreviationapplies to the word used alone. The abbreviation indi-cated “(comb form)” applies in combination with abbre-viations of other words to form an abbreviation for aword combination such as CRT for Cathode Ray Tube.

3.8 Colors

Two abbreviations are listed in sections 5 and 6 forcolor name. The three-letter abbreviation is preferredfor notes on drawings and in text. The other abbreviationis used where a shorter designation for colors is needed.

2

3.9 New Abbreviations

The development of a new abbreviation will be con-sidered for inclusion in this Standard based on the fol-lowing minimum criteria:

(a) A genuine need for the abbreviation has beendemonstrated.

(b) The abbreviation does not contain subscripts andsuperscripts.

(c) The term to be abbreviated should be five or moreletters.

(d) The abbreviation does not duplicate abbreviationsdefined or established in other standards.

(e) The abbreviation meets the intent of the scope ofthis Standard.

(f) The term to be abbreviated would have wide-spread application.

4 APPENDICES

4.1 Chemical Elements

The International Union of Pure and AppliedChemistry’s elements and their symbols appear inAppendix A. The symbols listed are not abbreviations,and are preferred to the abbreviations listed in sections5 and 6 for scientific and technical work. However, theseabbreviations may continue to be used in fields wheretheir use has been established by long standing practice.

4.2 Engineering Societies

A partial listing of Engineering Societies andIndustrial Associations and their abbreviations appearin Appendix B.
