The formulation and application of reference designations for electrical and electronics parts and equipment are covered. The reference designations of this standard are intended for uniquely identifying and locating discrete items on diagrams and in a set, as well as for correlating items in a set, graphic symbols on diagrams, and items in parts lists, circuit descriptions, and instructions. Three methods are given for forming and applying reference designations: the unit number method, the location numbering method, and the location coding method. A complete reference designation may incorporate reference designations formed by the use of any of these methods at any level from basic parts to complete units.
