Scope: This document specifies the rules and graphical symbols for the representations of splines and serrations in technical product documentation. Two methods of representation are specified: a) complete representation; b) simplified representation. The rules and graphical symbols specified in this document are applicable to detail drawings of parts (shafts and hubs) and to assembly drawings of joints. NOTE For uniformity, all the figures in this document have been drawn in the first-angle orthographic projection. A third-angle orthographic projection could equally have been used without prejudice to principles established.
