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) true 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 been used without prejudice to the principles established.
