This part of ISO 4156 provides the data and indications necessary for the design and manufacture of straight
(non-helical) side-fitting cylindrical involute splines.
Limiting dimensions, tolerances, manufacturing errors and their effects on the fit between connecting coaxial
spline elements are defined in the equations and given in the tables. Unless otherwise specified, linear
dimensions are expressed in millimetres and angular dimensions in degrees.
