scope:

This International Standard specifies the rules and graphical symbols for the representations of splines and serrations on technical drawings. Two methods of representation are specified as follows: a) Complete representation; b) Simplified representation. The rules and graphical symbols specified in this International Standard are applicable to detail drawings of the parts (shafts and hubs) and to assembly drawings of joints. NOTE - For uniformity all figures in this International Standard are drawn in the first-angle orthographic projection. It should be understood that the third-angle orthographic projection could equally well have used without prejudice to principles established.
