本标准规定了电子图文件中使用的电子符号的生成要求，这些电子图定义了电子产品的电气互连性。这些描述涉及定义电路配置所需的原理图符号、逻辑符号或布尔真值表。在适当的情况下，该标准还包括用于定义电路流、电气或功能限制的方法，或用于设计或维护电子产品的维护测试程序。这些要求涉及硬拷贝和电子数据描述。31页。

This standard establishes the requirements for generation of electronic symbols used in the documentation of electronic diagrams that define the electrical interconnectivity of electronic products. 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. 31 pages.
