23、 Stern, U.S. Department of the Army, ARDECCORRESPONDENCE WITH THE Y14 COMMITTEEGeneral. ASME Standards are developed and maintained with the intent to represent theconsensus ofconcerned interests. Assuch, users ofthis Standard mayinteract with theCommitteeby requesting interpretations, proposing rev
24、isions, and attending Committee meetings. Corre-spondence should be addressed to:Secretary, Y14 Standards CommitteeThe American Society of Mechanical EngineersThree Park AvenueNew York, NY 10016-5990Proposing Revisions. Revisions are made periodically to the Standard to incorporate changesthatappear
25、necessaryor desirable,asdemonstratedbytheexperience gainedfromtheapplicationof the Standard. Approved revisions will be published periodically.The Committee welcomes proposals for revisions to this Standard. Such proposals should beas specific as possible, citing the paragraph number(s), the propose
26、d wording, and a detaileddescription of the reasons for the proposal, including any pertinent documentation.Attending Committee Meetings. The Y14 Standards Committee regularly holds meetings ortelephone conferences, which are open to the public. Persons wishing to attend any meeting ortelephone conf
27、erence should contact the Secretary of the Y14 Standards Committee or check theWeb site at http:/www.asme.org/codes/.viASME Y14.38-2007ABBREVIATIONS AND ACRONYMS FOR USE ON DRAWINGSAND RELATED DOCUMENTS1 SCOPE AND PURPOSE1.1 ScopeThe abbreviations and acronyms, hereinafter referredto as “abbreviatio
28、ns,” listed in this Standard are usedon engineering drawings and related documentation.1.2 PurposeThe 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
29、 usingdrawing or related document. It is not the intent of thisStandardtoincludeabbreviationsdefinedorestablishedin other standards such as those for scientific termsand notations. However, an exception is made for thoseabbreviationsthathavewidespreaduseandrecognition,for example, AM for amplitude m
30、odulation, and FM forfrequency modulation (radio).1.3 Abbreviations and Letter SymbolsSince 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
31、)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 invo
32、lved, such as theequality sign (p) or the division sign (/).1.4 Abbreviation Lists FormatAbbreviations 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 w
33、ith lower case characters. Where upper caseabbreviations are shown in the “Text” column, they areacontinuationof priorusageandare generallyformajorsystems or are recognized as having significant applica-tionswhenusedintext.Bracketedmodifiersmayappearwith certain terms indicating alternate technology
34、-specific applications for that term.12 WHERE AND HOW ABBREVIATIONS SHOULD BEUSED2.1 Where to Use AbbreviationsAbbreviations are to be used only where necessary tosave time and space. Even though this Standard estab-lishesabbreviationsformanyterms,extremecareshouldbe exercised in their use. Since th
35、ey may have to beinterpretedbypeopleofvaryingbackgrounds,abbrevia-tions should be used only where their meaning isunquestionablycleartotheintendedreader.Wherethereis doubt that the reader will understand the meaning,spell out the word or complete phrase where first used,followed by the abbreviationo
36、r acronym in parentheses.When in doubt, spell it out.2.2 Duplicate AbbreviationsThe same abbreviation is included in this Standardfor several different terms due to established practice.Careshouldbeexercisedto assurethatthepropermean-ing will be interpreted when using such abbreviations.3 BASIC PRIN
37、CIPLES3.1 Abbreviations for AcronymsSections 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 PunctuationAn abbre
38、viation spelling a whole word shouldinclude a period if the abbreviation could bemisinterpreted.3.3 SpacingSpaces shall not be inserted within an abbreviation.3.4 CapitalizationAbbreviations included in the “Drawings” column ofsection 5, provide the form for use on drawings anddocuments produced in
39、upper case characters. Theabbreviations in the “Text” column provide the formrequired for lower case characters. However, theseabbreviations may be capitalized when required forASME Y14.38-2007emphasis. Abbreviations that are capitalized in the“Text” column are a continuation of prior usage andin ge
40、neral are abbreviations for major systems or arerecognized as having significant application when usedin text. Abbreviations are not listed in the column formanyshortwords.Ifspacelimitationsmakeitnecessaryto abbreviate such terms, the abbreviation that appearsin the “Drawings” column shall be used e
41、xcept for sub-stitution of lower case letters.3.5 Syntactical EndingsUnless 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
42、; “calc” for calculate, calculated,calculating, and calculation.3.6 Word CombinationsAn 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 abbrevia
43、tions may becombined when necessary if there is no abbreviationlistedforthecombination;e.g.,theabbreviationforaver-age “avg” and temperature “temp” can be combined as“avg temp” for average temperature.3.7 Combining FormsWhere two abbreviations are listed for the same wordsuch as “cath” for “cathode”
44、 and “c” for “cathode,” asin“cathoderaytube,(combform),”thefirstabbreviationapplies 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 ColorsTwo
45、 abbreviations are listed in sections 5 and 6 forcolor name. The three-letter abbreviation is preferredfornotesondrawingsandintext.Theotherabbreviationis used where a shorter designation for colors is needed.23.9 New AbbreviationsThe development of a new abbreviation will be con-sidered for inclusio
46、n 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 abbreviations
47、defined 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 APPENDICES4.1 Chemical ElementsThe International Union of Pure and AppliedChemistrys elements and their symbols appear inAp
48、pendix 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
