ČSN EN ISO 6413

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.
