Reference Designations for Electrical and Electronics Parts and Equipment

Abstract

This information covers the use of reference designations for electrical and electronics parts and assemblies. The reference designations are intended for uniquely identifying and locating discrete items on diagrams and in the hardware, and for correlating items in the hardware, graphic symbols on diagrams, and items in parts lists, circuit descriptions, and instructions. This standard uses three methods for forming and applying reference designations: the unit number method, the location numbering method, and the location coding method.
