This standard establishes the requirements for generation of electronic symbols used in the documentation of electronic diagrams that define the electrical interconnectivity of electronic parts. The descriptions pertain to schematic symbols, logic symbols or Boolean truth tables required to define the circuit configuration. Where appropriate the standard also includes methodology for defining circuit flow, electrical or functional restrictions, or maintenance test procedures used to design or maintain the electronic product. The requirements pertain to both hard copy and electronic data descriptions.

Purpose

The purpose of the standard is to develop a protocol that fits well into both manual and automated documentation of electronic diagrams. In addition, the methodology permits the symbols to be placed and adjusted in a manner that facilitates showing how an electronic function can interact with other functions. In this regard, the symbol Input, Output, ground and voltage arrangement must fall on some form of the Cartesian coordinate system in order to facilitate the use of the symbols in automated diagramming tools.
