IEEE 315A-1986 pdf free.American National Standard IEEE Standard Supplement to Graphic Symbols forElectrical and Electronics Diagrams.
IEEE 315A is intended to provide addi-tional graphic symbols and information on in-ternationally approved graphic symbols neededfor use for electrical and electronics diagrams.
This supplement provides graphic symbolsfor use on all electrical or electronics diagramsexcept for those required for
(1) Logic circuit diagrams.See ANSI/IEEEStd 91-1984[4]1.
(2)Architectural plans. See ANSI Y32,9-1972 [2]and IECPublication 617 (1983)[22] Part 11, ch IV.
(3) Street maps and building system layoutsfor cable TV application. See ANSI/IEEE Std623-1976 [8]and IEC Publication 617 (1983)[22] , Part 11,ch III.
This supplement places the IEC Publication617 new material in a practical sequence withrelated material in ANSI/IEEEStd 315-1975[7]. Except where the nature of the revisionsdictate otherwise (for reasons of clarity) exist-ing ANSI/IEEEStd 315-1975 [7]text is notrepeated.
