18、revision and expansion of American National Standard Graphic Symbols forElectrical and Electronics Diagrams, Y32.2-1970 (IEEE Std 315-1971). A variety of specialized symbols originally used for aircraft applications have been added to make this standard morecomprehensive. To improve coordination wit

19、h IEC publication 117, IEC approved versions of capacitor, transformer,delay, associated conductors and specialized ground symbols have been added as alternates to those long used andstandardized in the United States. A number of small changes have made the existing material more closely parallel to

20、IEC Publication 117. Symbols have been added to cover additional devices in the photo sensitive semiconductor andspecialized semiconductor fields, as well as for an electronic flash lamp. Known errors have been corrected and someitems have been clarified.The reference designation class letters were

21、revised to include the added new device symbols and to clarify the DS andLS categories. “D” is now listed as an alternate to the common “CR” for the common semiconductor diode family ofdevices.All of the symbols are designed so that their connection points fall on a modular grid. This should help th

22、ose who usea grid basis for the preparation of diagrams. By proper enlargement of the symbols the usual coordinate-grid sizes canbe matched. Most symbols appearing in this standard were reproduced form original drawings prepared for theMergenthaler Diagrammer.A substantial effort has been made to ha

23、ve this American National Standard compatible with approved InternationalElectronical Commission (IEC) Recommendations (IEC Publication 117, in various parts). Electrical diagrams are afactor in international trade; the use of one common symbol language ensures a clear presentation and economicaldia

24、gram preparation for a variety of users. Members of the preparing committee have been active in transmitting USAviewpoints to the cognizant IEC Technical Committee.Alternative symbols are shown only in those cases where agreement on a common symbol could not be attained at thistime. It is hoped that

25、 the number of alternative symbols will be reduced in future editions.The symbols in this standard represent the best consensus that can be attained at this time. Standardization, however,must be dynamic, not static, and any solution of a problem should be tested through use and revised if necessary

26、. It isanticipated that the contents of this standard will be modified as future needs dictate; such modifications will be madeavailable through the issuance of approved supplements. Suggestions for improvement are welcomed. They should beaddressed to:Secretary, IEEE Standards BoardInstitute of Elec

There has been close cooperation between the industry and DOD representatives toprovide one standard that can be universally used, rather than separate documents with their tendency

While credit for this accomplishment is due all participants and the organizations they represent,particular mention is given to the U.S. Department of Defense, without whose strong support in reaching theobjectivestandard symbols acceptable to both industry and the mil
